Texte intégralRésumé :
ABSTRACT Since times immemorial, dentists have faced the challenge of providing accord between function and esthetics. The occlusal plane, lost in patients rendered edentulous, should be relocated if complete dentures are to be esthetically and functionally satisfactory. Changes in the plane of occlusion modify the physical and functional relationship of the oral musculature leading to an alteration in function, comfort and also the esthetic value. Considering the importance of the accurate establishment of the location and the effect of the inclination of the established occlusal plane on function, esthetics and speech, a method to conform it to the occlusal plane that existed in the natural teeth seems necessary. This paper describes a custom-made instrument to check for the parallelism of ala-tragus line to the occlusal plane and also to check for the parallelism of occlusal plane to interpupillary line.

ABSTRACT Aim This study was undertaken to analyze the clinical usefulness of the maxillomandibular bisector, its reproducibility, its validity and its relationship to the functional occlusal plane, the bisecting occlusal plane and the nature of its cant. Materials and methods Thirty pretreatment lateral cephalograms, each of adolescents (above 18 years of age) and children (10- 12 years), seeking orthodontic treatment were randomly selected and the Wits technique of anteroposterior measurement was used to compare A-B values measured to the new plane with those measured to the functional occlusal plane (FOP) and to the traditional or bisecting occlusal plane (BOP). Results Present study showed that MM bisector plane is more reproducible and valid reference plane, than the FOP and BOP. Conclusion A new plane, geometrically derived from the dental base planes, has been tested as an occlusal plane substitute for the measurement of anteroposterior jaw relationships. It lies close to but at an angle and inferior to the traditional occlusal planes and is highly reproducible at all times. Clinical significance Maxillomandibular planes angle bisector may be a useful adjunct for the cephalometric assessment of sagittal relationship of the patient.

Texte intégralRésumé :
Proper occlusal plane is an essential consideration when multiple long span posterior restorations are designed. The determination of the occlusal plane can have a profound effect on the short and long term success of a restorative case. Purpose of Study. (1) To determine the appropriate occlusal curve for individual patients. (2) To compare the deviation of the clinical occlusal curve with the ideal ones. Materials and Methods. A total of 20 subjects were examined and study models were made of their maxillary and mandibular dentition. Inter-occlusal records were made and the casts were articulated in semiadjustable articulator. An ideal occlusal plane was created. The distance of the farthest cusp tip from the Broadrick curve was measured along the long axis of the tooth for each individual. Paired t-tests were used to compare the findings between subjects and controls. Results. A statistically significant difference P<0.05 was found in the deviation from the Broadrick curve between patients who have lost posterior teeth and the control group who had a full dentition with no missing teeth. Conclusion. Proper utilization of the broadrick flag on a semi-adjustable articulator will allow for a correct determination of the occlusal plane.

Texte intégralRésumé :
Background: Camouflage treatment of skeletal Class II malocclusion can be performed using extraction or non-extraction techniques. These treatments can cause changes in occlusal plane. Steep occlusal plane during corrective treatment generally relapses after active orthodontic treatment, resulting in unstable interdigitation. Purpose: This study aims to determine and evaluate changes in occlusal plane inclination in skeletal Class II malocclusion cases using extraction or non-extraction techniques of the permanent maxillary first premolar. Methods: The samples consisted of initial and final cephalometry of 40 adult patients with skeletal Class II malocclusion divided into two groups, namely extraction of the permanent maxillary first premolar and non-extraction group. The inclination of occlusal planes in both groups was measured using the ImageJ software, then the factors associated with these changes were observed. Furthermore, the occlusal plane inclination was compared between the extraction and non-extraction groups by using t-test. Results: The occlusal plane inclination in the non-extraction group increased slightly, while the inclination in the extraction group increased significantly (p = 0.017, p-value < 0.05). However, there was no correlation found in the occlusal plane inclination between the extraction and non-extraction groups (p = 0.07, p-value < 0.05). Conclusion: Class II malocclusion correction with either extraction or non-extraction of the maxillary first premolar increased the inclination of the occlusal plane. This study indicated that control of the occlusal plane inclination is highly essential.

Texte intégralRésumé :
ABSTRACT Background Orientation of the occlusal plane is one of the most important clinical procedures in the prosthodontic rehabili- tation of edentulous patients but definitions of the ala-tragus line (ATL) causes confusion, because the exact points of reference for this line are not clear. Aim The aim of this study was to corroborate a correlation between Camper's plane and natural occlusal plane in normal dentulous subjects and to ascertain the most relevant posterior reference point for establishing Camper's plane. Materials and methods In this study, 40 subjects with com- plete natural dentition and Angel's Class I occlusal relationship were selected. The subjects were photographed in sitting erect posture with head unsupported while clenching on a fox plane. The angles between the following lines were measured using digital screen protractor, the occlusal plane and Ala to superior border of tragus, the occlusal plane and Ala to middle border of tragus, as well as occlusal plane and Ala to inferior border of tragus. Descriptive statistics, one sample t-test and, independent t-test were done to analyze the data. Results There was no parallelism between the occlusal plane and ATL with three different posterior ends and one sample t-test showed that the angles between them were significantly different from zero (p < 0.001). However, the inferior border of the ATL had the lowest mean angle, 1.99° (4.32) and was almost parallel to the occlusal plane. Conclusion Ala-tragus line from Ala of the nose to the inferior border of tragus as a posterior reference point can be considered as a reliable occlusal plane for complete denture fabrication.

Texte intégralRésumé :
Orientation of occlusal plane for complete dentures play a vital role as it affects all the basic requirements of complete dentures. Depending on soft tissue landmarks for orienting occlusal plane seems to be unreliable. Cephalometrics were introduced in Prosthodontics to orient the occlusal plane in the same position as it was with the lost natural teeth.
In the present study, 60 lateral cephalometric radiographs of a group of male and female dentulous subjects of Indian and Nepali origin (30 subjects in each group) were obtained and tracings were made. All the subjects selected were in the age group of 20-30 years in whom the facial growth was completed. Angular measurements were made between FH (Frankfort Horizontal plane)- CP (Camper's Plane), FH-OP (Occlusal Plane) and CP-OP and subjected to statistical analysis to determine the degree of separation between these planes in Indian and Nepalese ethnic groups.
The absolute parallelism between the natural occlusal plane and Camper's plane were not proven in both Indian and Nepalese subjects involved in this study. This significantly reduces the reference values of these planes in Prosthodontics.

Objetivo: avaliar a relação entre o tipo facial e as variações da inclinação do Plano Oclusal e do ângulo ANB em indivíduos com oclusão normal. Material e Método: a amostra foi composta por 98 telerradiografias em norma lateral de 98 indivíduos (47 homens e 51 mulheres) com idade média de 15,2 anos (desvio padrão de 1,4 anos), com oclusão normal e perfil harmonioso. As radiografias foram digitalizadas em escala 1:1 eo programa Nemoceph (Nemotec® - Espanha), foi usado para a análise cefalométrica, que incluiu as cinco variáveis que segundo Ricketts definem o padrão facial, a relação sagital (SNA, SNB, ANB, N.S.Ba, SN.Go-Me, ANB individualizado, AP-BP e Wits)e ainclinação do Plano Oclusal (PLO.Linha S-N, PLO.PF, PLO.PP, PLO.XiPm e PLO.PM). Os dados foram analisados estatisticamente com um nível de significância de 5%. Resultados: acomposição dos tipos faciais foi: 11% dólicofaciais, 39% mesofaciais e 50% braquifaciais. Os valores médios e intervalo de confiança de 95% das variáveis que avaliaram a inclinação do plano oclusal, para os tipos faciais dólico, meso e braqui foramrespectivamente: PLO.SN: 21,7° (± 2,14°), 17,0° (± 1,10°) e 15,1° (± 1,43°); PLO.PF: 13,5° (±1,77)°, 10° (SD 1,01°) and 8,1° (± 1,25°); PLO.PP: 12,2° (±1,99°), 9.1° (± 1,31°) e 8,1° (± 1,21°); PLO.Xi-Pm: 20,5° (± 1,76°), 19,2° (± 0,96°) e 16,4° (± 1,12°); PLO.PM: 17,5° (± 2,02°), 15,3° (± 1,27°) e 12,1° (± 1,19°). Os valores médios das variáveis que avaliam a relação sagital maxilomandibular respectivamente foram: ANB: 3,8° (± 0,98°), 2,5° (± 0,62°) e1,3° (± 0,53°); distância AP-BP: 7,3mm (± 2,19mm), 3,4mm (± 0,94mm) e 1,9mm (± 0,78mm); ANB Individualizado: 4,7° (± 0,70°), 4,4° (± 0,43°) e 3,7° (± 0,39°); Wits: 1,8mm (± 1,27mm), -2,4mm (± 0,83mm) e -3,5mm (± 0,92mm). Conclusões: Tanto as variáveis que avaliam a inclinação do Plano Oclusal como as variáveis que avaliam a relação sagital maxilo-mandibular ANB e AP-BP, caracterizam-se diferencialmente segundo o tipo facial, observando-se um decréscimo dos valores do tipo dólicofacial para o braquifacial.Objective: evaluate the relation between the facialtype and the inclination of the occlusal plane and ANB angle in individuals with normal occlusion.Material and Methods: the sample was composed of 98 radiographs, in lateral norm, of 98 individuals (47 men, 51 women), with an average age of 15.2 years (standard deviation of 1.4 years), normal occlusion and harmonic profile.The radiographs were digitalized in a 1:1 scale and the software Nemoceph (Nemotec® - Spain) was used for the cephalometric analysis, which included Rickettsfive variables thatdetermine the facial type, the saggital relation (SNA, SNB, ANB, N.S.Ba, SN.Go-Me, ANB individualized, AP-BP and Wits) and theinclination of the occlusal plane (OPL.S-N, OPL.PF, OPL.PP, OPL.XiPmand OPL.PM). The data was analyzed statistically with a significance level of 5%.Results: the composition of the sample by facial type was: 11% dolichofacial, 39% mesofacial e 50% braquifacial.

Resumo: O presente trabalho objetiva verificar a validade de algumas referências anatômicas para determinar a altura do plano oclusal, quando da confecção de uma prótese total dupla, utilizando-se a técnica da zona neutra ou do equilíbrio muscular. Também foi avaliada a associação dos métodos de deglutição, métrico, estético e fonético para se determinar a dimensão vertical de oclusão. Para os 42 indivíduos que receberam as dentaduras duplas e as utilizaram por 15 dias para adaptação, foi feita uma telerradiografia em norma lateral com as superfícies oclusais e bordas incisais dos dentes inferiores previamente assinaladas com substância radiopaca. Foi executado um traçado cefalométrico em desdentados e os resultados comparados com os parâmetros universalmente aceitos como normais de padrões cefalométricos, usando-se, principalmente, a Análise de Ricketts apenas nos aspectos que interessavam, complementada por outros referenciais de pesquisa. Os resultados obtidos após a avaliação estatística permitiram concluir que: 1- A altura do lábio inferior em repouso, o maior diâmetro da língua, a ponta da língua, a metade da papila retromolar e o relativo paralelismo entre o rebordo alveolar superior e inferior são referências seguras para se determinar a altura do plano oclusal em próteses totais duplas, confeccionadas com base na técnica de zona neutra ou equilíbrio muscular quando comparado aos padrões de cefalometria. 2- A associação dos métodos de deglutição, métrico, fonético e estético para determinar a dimensão vertical de oclusão em indivíduos desdentados que receberam prótese total dupla também se mostrou eficiente quando comparada aos padrões cefalométricos. 3- Como mais uma referência para determinar a dimensão vertical de oclusão em pacientes que receberão uma prótese total dupla, pode-se utilizar as fórmulas: proporção espinha nasal anterior
Abstract: This dissertation aims at checking the validity of some anatomical references used to determine the height of the occlusal plane when manufacturing complete dentures based on the neutral zone or muscular balance technique. The association of the deglutition, metric, esthetic and phonetic methods was also evaluated to determine the occlusal vertical dimension. The 42 individuais who received double dentures and used them for 15 days for adaptation had a teleradiography taken at lateral norm, with the occlusal surfaces and incisal edges of the lower teeth previously marked with a radio-opaque substance. A cephalometric outline within the toothless individuals' limitations was done, and the results were compared to the parameters universally accepted as normal cephalometric standards. The Ricketts Analysis was mainly used to compare results, but only when it suited our purposes, and it was complemented by other research references: The results obtained after statistical evaluation show: 1- When compared to cephalometric standards, the height of the lower lip at rest, the largest diameter of the tongue, the tip of the tongue, half the retromolar pad and the relative parallelism between the upper and lower alveolar rim are sure references to determine the height of the occlusal plane when manufacturing double total prosthesis based on the neutral zone or muscular balance technique. 2- The association of deglutition, metric, esthetic and phonetic methods to determine the occlusal vertical dimension in edentulous individuais receiving double complete dentures has also proved efficient when compared to cephalometric standards. 3- The formulas below can be used as another reference to determine occlusal vertical dimension in patients receiving a complete dentures: ratio anterior nasal spine I mentum = 1.3 ratio nasion I anterior nasal spine or ratio nose basis I mentum = 1.19 ratio eye external corner I buccal commissure

Resumo: Foram examinados e tratados dez (10) pacientes do sexo feminino, na faixa etária entre 23 e 50 anos de idade, com sinais e sintomas de alterações funcionais do sistema estomatognático, divididos em dois grupos de cinco pessoas cada. Um grupo foi submetido a tratamento com aparelhos de cobertura oclusal plana e, o outro grupo tratado com aparelhos de pistas duplas tipo Planas, 1987. Os sintomas relatados com mais freqüência, foram as dores de cabeça seguidas de sensação de desconforto muscular. Todos os pacientes foram submetidos aos seguintes procedimentos: anamnése, exame clínico, exame físico através da palpação muscular, moldagem e modelos de estudo. Além dos exames e procedimentos preliminares, foram realizadas duas fases laboratoriais: uma para a captação dos potenciais elétricos dos músculos estudados e, a outra fase para o enceramento dos aparelhos em articulador semi-ajustável e respectivas prensagens em resina acrílica incolor termicamente ativada. Os aparelhos foram instalados e neles foram realizados os primeiros ajustes em relação aos dentes antagônicos. A primeira captação dos potenciais elétricos ocorreu antes da instalação dos aparelhos; a segunda aos 30 dias de uso e a terceira, após o refinamento oclusal, por volta de 60 a 120 dias do início do tratamento. A análise dos potenciais elétricos obtidos durante o período de tratamento com aparelhos de cobertura oclusal plana e do tipo Planas, com a mandíbula em posição postural, na mordida incisivo com resistência, na mordida molar com resistência e mordida molar sem resistência, evidenciou que os pares de músculos estudados, funcionalmente, com o decorrer da terapêutica proposta, tenderam a se equivaler. Em relação ao tipo de aparelho utilizado, ambos mostraram-se efetivos, sendo o de melhor manipulação, os de cobertura oclusal plana. O ajuste oclusal por desgaste seletivo, mostrou ser, importante do ponto de vista da manutenção da posição da mandíbula, conseguida com o uso dos aparelhos intra-orais, quando avaliado através da captação dos potenciais elétricos dos músculos estudados e do relato da remissão dos sinais e sintomas clínicos
Abstract: Ten female patients, with age between 23 to 50 years old, were submitted to a clinical examination and were treated with intra oral appliances, since all of them presented symptomatology related to functional alterations of the stomatognathic system. This group of 10 patients were divided into two groups of 05 patients each. The first group started the treatment wearing flat occlusal splints and the second group started the treatment wearing Planas's appliances with functional tracks (1987). The major and the most importants complaints of all patients were headache followed by muscle discomfort sensation. The all patients were also submitted to anamnesis and during the clinical examination a muscle palpation was perfomed by the professional as well as the impression of the jaws followed the execution of the respective stone cast models. Two laboratory procedures were also realized, firstly for determination of the eletrical potential of the masseter and temporalis and after for the waxing, the appliances were fixed in semi-adjustable articulador and were posteriorly cast with an incolor acrylic resin activated thermically. The appliances were installed in the respective patients mouths and the first adjustments were realized based on the antagonists teeth. The determinations of muscle electrical potentials were performance, firstly, before the instalation of the appliances, after 30 days of their usage, and finally in the period between 60 and 120 days after beggining of the treatment associated with the occlusal adjustment. The muscle electrical potential were obtained during the treatment of the 2 groups of patients, with the respective intra oral appliances referred previously, with the mandible at differents positions such as: postural position, incisor bitting with resistance, molar bitting with resistance and molar whithout resistance, showed that the pair of muscles studied had a functional behavior similar to each other independently of the treatment proposed.

Resumo: O conceito das desordens temporomandibulares (DTM), as define como um conjunto de alterações articulares e musculares na região orofacial, caracterizados principalmente por dor, ruídos nas articulações temporomandibulares (ATM) e alteração da função mandibular, podendo estar associada as alterações cervicais oriundas das Desordens Crânio Cervicais. Estudos eletromiográficos demonstraram que mudanças na posição de cabeça podem alterar o padrão de atividade dos músculos da mastigação e a posição da mandíbula. Em função destes aspectos, o objetivo deste trabalho foi avaliar a atividade eletromiográfica dos músculos supra-? hioideos, esternocleidomastoide, trapézio, temporal anterior e masseter em 15 voluntários desdentados totais, com dimensão vertical de oclusão (DVO) baixa, portadores de DTM submetidos a terapia com aparelhos oclusais planos, que foram tratados de acordo com o protocolo clínico do CETASE (Centro de Estudos e Tratamento das Alterações Funcionais do Sistema Estomatognático) da FOP -? Unicamp. As avaliações eletromiográficas foram realizadas simultânea e bilateralmente, no período inicial e aos 30, 60 e 90 dias de tratamento, com a mandíbula nas posições de repouso e fechamento isométrico com resistência do aparelho. Os resultados demonstraram na posição de repouso um aumento significante na atividade eletromiográfica do músculo esternocleidomastoideo direito, quando comparados os períodos inicial e após 60 e 90 dias (p=0,03), e nos músculos trapézio médio direito após 60 dias (p=0,03), e esquerdo, após 90 dias de tratamento (p=0,04).Na situação de fechamento isométrico com resistência resultados significantes foram encontrados para as atividades eletromiográficas dos músculos supra-?hioideos direito (p=0,04) e trapézio médio direito (p=0,04) e esquerdo (p=0,02), após 90 dias de tratamento. Uma correlação significante pôde ser observada quando comparamos bilateralmente todos os músculos avaliados, nas duas situações (p<0,05). Após a terapia com aparelhos oclusais planos ocorreu uma equalização funcional significativa na atividade eletromiográfica dos músculos cervicais e supra-?hioideos, podendo sugerir que a alteração na posição mandibular influencia na atividade elétrica dos músculos cervicais
Abstract: The concept of temporomandibular disorders (TMD), define them as a set of joint and muscle disorders in the orofacial region, mainly characterized by pain, noise in the temporomandibular joints (TMJ) and altered mandibular function, and may be associated with cervical changes arising from Cranio Cervical Disorders. Electromyographic studies have shown that changes in head position can change the pattern of the mastication muscles activities and the jaw position. Based on these aspects, the aim of this study was to evaluate the electromyographic activity of the supra-?hyoid muscles, sternocleidomastoid, trapezius, anterior temporal and masseter in 15 edentulous volunteers with low vertical dimension of occlusion (VDO), TMD treated with plan occlusal splints according to the clinical protocol of CETASE (Center for Studies and Treatment of Functional Changes of the Stomatognathic System) FOP -? Unicamp. The electromyographic evaluations were performed simultaneously and bilaterally, before the beginning of the treatment and at 30, 60 and 90 days of treatment, with the jaw at rest position and isometric closure with resistance of the splint. The results showed in the jaw rest position a significant increase in electromyographic activity of the right sternocleidomastoid muscle, when comparing the initial period and after 60 and 90 days (p = 0.03), and right medium trapezius muscles after 60 days (p = 0.03), and left medium trapezius muscles, after 90 days of treatment (p=0.04). Related to isometric closure with resistance significant results were found for the electromyographic activity of the right suprahyoid muscles (p=0.04) and right (p=0.04) and left middle trapezius (p=0.02) at 90 days after treatment. A significant correlation was observed when comparing bilaterally all muscles in both conditions (p<0.05). After the plan occlusal splint therapy, there was a significant functional equalization of the electromyographic activity of neck and suprahyoid muscles, suggesting that changes in mandible position can influence the electrical activity of cervical muscles

Mise en place d’une chaîne méthodologique de la faisabilité à la clinique ». Thesis, Bordeaux, 2015. http://www.theses.fr/2015BORD0372/document.
Texte intégralRésumé :
Le but de ce travail était la mise en place d’une chaîne méthodologique de planification virtuelle d’une ostéotomie sagittale des branches mandibulaires (OSBM) et son transfert au bloc opératoire. Dans la première partie, les méthodes classiques de planification et de transfert sont exposées. Habituellement réalisées à partir de modèles en plâtre sur articulateur, la planification et la production de guides occlusaux chirurgicaux souffrent d’une imprécision potentiellement à l’origine de troubles fonctionnels temporo-‐mandibulaires. Le contrôle per-‐opératoire du condyle mandibulaire lors de l’OSBM est un élément de stabilité squelettique dont dépend la qualité du résultat fonctionnel. Une évaluation des pratiques professionnelles des chirurgiens maxillo-‐faciaux a été réalisée sur ce point. Une méthode de positionnement condylien utilisant un dispositif, moins fréquemment utilisée que la méthode empirique, est proposée comme présentant le meilleur rapport bénéfice/risque. Cette méthode a été reproduite virtuellement à travers les différents maillons de la chaîne méthodologique. Des techniques innovantes informatisées d’acquisition, de conception et modélisation, et d’impression en 3 dimensions ont été utilisées. Dans la seconde partie, la méthodologie de chacun des maillons de la chaîne a été présentée et évaluée, soit sur sujets cadavériques, soit sur patients. L’objectif était de démontrer la faisabilité de la chaîne. Le maillon « acquisition et extraction de surface » a mis en exergue le problème des artéfacts dus aux matériaux métalliques dentaires ou orthodontiques. Dans 90% des cas le maillage obtenu était satisfaisant, permettant de s’affranchir des modèles en plâtre. Le maillon « planification chirurgicale virtuelle » a montré une valorisation par rapport à la technique classique en terme de prévention des interférences des pièces osseuses déplacées. Le maillon « modélisation et impression du guide chirurgical » a décrit les étapes d’invention d’un guide de positionnement occlusal et condylien (OCPD : occlusal and condylar positionning device). Ses caractéristiques techniques, ses modalités de production par impression 3D ainsi que son utilisation peropératoire, ont été précisées. Enfin le maillon « évaluation de l’OCPD » a permis de montrer la faisabilité de la méthode et l’équivalence clinique, technique et biologique de ce dispositif médical sur mesure par rapport à ceux utilisés dans la méthode classique. Enfin le positionnement condylien obtenu grâce à ce dispositif a été évalué de manière préliminaire et comparé aux données de la littérature. Grâce à l’OCPD, nous avons montré la possibilité de transférer au bloc opératoire la planification virtuelle d’une OSBM contrôlant la position des condylesThe purpose of this work was the implementation of a methodological chain for bilateral sagittal split osteotomy (BSSO) virtual planning and its transfer in the operating room. In the first part of the work, usual methods for planning BSSO are exposed. Usually realized from plaster models on articulator, the planning and the occlusal surgical guides production are at risk of temporo-‐mandibular functional disorders. The quality of the functional result depends on the correct positioning of the mandibular condyle, considered as a skeletal stability element. An assessment of the maxillofacial surgeons practices was realized regarding intra-‐operative condyle positioning. Using a condylar positioning device (CPD),less frequently employed than the empirical method, meets an acceptable benefit/risk balance. This method was virtually reproduced through various steps of the methodological chain described. Computerized innovative techniques for three-‐dimensional acquisition, design and manufacturing were used. In the second part of the work, the methodology of each step of the chain was presented and estimated, either on cadaveric subjects, or on patients. The aim was to demonstrate the feasibility of the whole chain. The “acquisition and surface extraction” step pointed the issue of artefacts due to dental or orthodontic metallic devices. Ninety % of the obtained meshes were satisfactory, allowing not to use plaster models. The “virtual surgical planning” step allowed reproducing the usual method and showed great interest in bone interferences prevention. The “modelling and printing of the surgical guide” step described the stages of occlusal and condylar positioning device (OCPD) invention. Its technical characteristics, its methods of manufacturing by 3D printing, and its intraoperative use were specified. The step “OCPD evaluation” showed the method feasibility and the clinical, technical and biological equivalence of this custom-‐made medical device as compared to those used in the usual method. Finally the condylar position obtained with this device was estimated in a preliminary clinical study and compared with the literature. Thanks to the OCPD, we showed the possibility of transferring in the operating room an OSBM virtual planning controlling condyles position

Texte intégralRésumé :
Objetivo: Avaliar por meio do estudo fotoelástico qualitativo as tensões geradas no longo eixo dos implantes e interimplantes nas regiões cervical, média e apical quando submetidos a diferentes carregamentos com ou sem interposição de placa oclusal plana. Método: Foram confeccionados quatro modelos fotoelásticos, com dois implantes hexágono externo (Neodent) localizados no espaço correspondente ao segundo pré-molar e segundo molar inferiores. Em cada modelo, foram instaladas supraestruturas metálicas parafusadas sobre os implantes. Os modelos fotoelásticos foram posicionados no polariscópio circular para distribuição das franjas isocromáticas em torno dos implantes e áreas interimplantes. Registros fotográficos foram obtidos antes e após a aplicação dos diferentes tipos de carregamento: 1- 30kg sem placa; 2- 30kg com placa; 3- 60kg sem placa; 4- 60kg com placa; 5- 90kg sem placa; 6- 90kg com placa. Resultados: Após as análises, observou-se a presença de tensão nos modelos sem a aplicação de carga oclusal após a aplicação do torque (20Ncm). A diminuição na magnitude de tensão com a aplicação da placa oclusal plana se tornou mais evidente após a aplicação de carga de 60kg. De modo geral, a maior magnitude de tensão se deu na região cervical para as áreas interimplantares e na região apical ao redor dos implantes, havendo uma diminuição de 57,77% entre as três magnitudes de cargas aplicadas após utilização da placa. Conclusões: Assim, os dados obtidos deste estudo demonstraram que a melhor distribuição de tensões nos implantes foi obtida com a interposição da placa oclusal plana, a partir da aplicação de carga de 60kg, com diminuição de 66,66%.Aim: To assess using qualitative photoelastic studies the tensions generated in the long axis of the implants and interimplants in the cervical, middle and apical regions when subjected to different loads with or without interposition of occlusal splint flat. Methods: Four photoelastic models were fabricated with two external hexagon implants (Neodent) located in the space corresponding to the second premolar and molar inferiors. In each model, screw-retained metal superstructures were installed on the implants. Photoelastic models were positioned in the circular polariscope for distribution of isochromatic fringes around the implants. Photographic records were obtained before and after application of different types of loading: 1- 30kg without plate; 2- 30kg with plate; 3- 60kg without plate; 4- 60kg with plate; 5- 90kg without plate; 6- 90kg with plate. Results: After the analysis, the presence of tension in the models without the application of occlusal load after torque application (20Ncm) was observed. The decrease in stress with the application of the occlusal splint flat became more evident after the application of 60kg load. Generally, the major stress magnitude occurred in the cervical region for interimplant areas and in the apical region around implants, with a decrease of 57,77%, between the three magnitudes of loads applied after use of plate. Conclusions: The data obtained in this studies demonstrate that the best stress distribution in the implants is obtained by interposing occlusal splint flat, with the application of a 60kg load, and a decrease of 66,66%.

Background: Orientation of the occlusal plane is one of the most important clinical procedures in prosthodontic rehabilitation of edentulous patients. Because of its effect on aesthetics, function and denture stability, it should be reconstructed as identical as possible to the occlusal plane of missing natural teeth. The use of the ala-tragus line to orient the occlusal plane is advocated by some authors. However, there is some controversy on the exact points of references of the ala-tragus line, since some researchers believe in using the lower border of the tragus, others believe in using the middle part of the tragus, and still others believe in using the upper part. In the past, cephalometric and photographic analysis has been used to investigate the relationship between the natural occlusal plane and anatomical structure in the skull. At present, this study aims at determining the most reliable ala-tragus line as a guide for the orientation of the occlusal plane by using cone-beam computed tomography (CBCT). Materials and Methods: A total of fifty-eight young adults (22 females and 36 males) with complete natural dentition were selected. Exclusion criteria included history of major trauma to the face, nose surgery, craniomandibular disorder syndrome, or previous orthodontic treatment. The metal indicators were attached to anterior and posterior reference points. The occlusal planes were determined by mesio-incisal angle of the maxillary central incisors and mesio-buccal cusp tip of the maxillary first or second molar. A 3D CBCT images was taken for each patient. The X, Y, and Z 3D space coordinates of each points would be located and obtained, then three points formed a plane. The angles between those planes were measured, and statistical analysis were carried out. Results: The measurement results are presented by mean values and standard deviations. The angle between the occlusal plane and Camper’s plane had the lowest mean value in the angle formed with Camp. 3L-Occ. 2 (7.43±4.88°) and the highest mean value in the angle formed with Camp. 1R-Occ. 1 (15.56±7.64°). And the angles between Camp. 3-Occ. 1/2 group had lower value than other groups. The differences between the planes in relation to the occlusal planes were found to be very highly significant (p < 0.001). It means no absolutely parallelism exists between the occlusal plane and the ala-tragus line. Conclusion: According to the result of the present study, there is no parallelism between the occlusal plane with two different posterior reference points and the ala-tragus line with three different posterior ends. The average angle between the occlusal plane connecting mesio-incisal angle of maxillary central incisors with mesio-buccal cusp tip of maxillary second molar and the Camper’s plane connecting the inferior border of ala with inferior border of tragus had the lowest mean angle (7.43～7.86°). This value is higher than the literature reports by other researchers. Within the limitations of this study, it may be summarized that the inferior border of the tragus with the inferior border of the ala of the nose was more accurate in orienting the occlusal plane than others.

The purposes of this study were estimating the relationship between HIP plane and occlusal plane, investigating the dental arch form and analyzing the correlation of dental arch form and occlusal plane in Taiwanese young adults with approximately optimal occlusion. Study casts of 100 young adults (50 males and 50 females) aged from 19 to 28 years were selected in this study. All the marked points on maxillary and mandibular casts of labial incisal edge angles, cusp tips of canines, premolars and molars were measured in three dimensions by a three-dimensional precise measuring device (CE-503V, Chien Wei Precise Technology Co., LTD). All the data of following items: (1) the angles among HIP plane (hamular notch-incisive papilla plane) and various definied occlusal plane; (2) the relative position of maxillary teeth landmarks to HIP plane and the center of the incisive papilla; (3) the relationship of the incisive papilla to the maxillary central incisor and canine; (4) the dental arch depths; (5) the dental arch widths; (6) the maxillary anterior arc radius; (7) the palatal vault depths were calculated and analyzed with SAS program (JMP version 4.02). The results are: 1. The occlusal plane defined as the mesial-labial incisal edge of upper right central incisor and mesial-buccal cusp tips of upper first molars had the included angle of 3.53±0.80º with HIP plane. There was no significant difference in gender (p>0.05). The occlusal plane defined as the mesial-labial incisal edge of upper right central incisor and mesial-buccal cusp tips of upper second molars had the smallest included angle with HIP plane (2.61±0.81º). There was no significant difference in gender (p>0.05). The occlusal plane defined as the mesial-labial incisal edge of upper right central incisor and mesial-palatal cusp tips of upper first molars had the largest included angle with HIP plane (7.72±1.60º). The female had significantly larger angle than the male (p<0.05). The occlusal plane defined as the mesial-labial incisal edge of upper right central incisor and mesial-palatal cusp tips of upper second molars had the included angle of 6.54±1.08º with HIP plane. There was significant difference in gender (p<0.05). 2. The mesial-labial incisal edge of upper central incisor was 7.30±0.64 mm anterior to the center of the incisive papilla. There was no significant difference in gender (p>0.05). 3. The intercanine line was 0.27±1.30 mm posterior to the center of the incisive papilla. There was no significant difference between male and female (p>0.05). 4. The maxillary anterior arc radius was 23.98±2.71 mm. Besides, the male had significantly larger radius than the female (p<0.05). 5. There were significant differences between female and male in dental arch depths (p<0.05). The female had deeper arch depth in the maxilary lateral incisor region, but the male had deeper arch depths in the mandibular canine and second molar of both arches. 6. The male had significantly wider dimensions than the female in maxillary arch widths (p<0.05). Except for the mandibular lateral incisor and canine areas, the mandibular arch widths of male were significantly wider than the female (p<0.05). 7. As for palatal vault depth, the male had significantly larger dimensions than the female (p<0.05) except for the lateral incisor area. Whether male or female, the deepest palatal vault depth was located in the first molar area. 8. Regarding the correlation of dental arch form and occlusal plane, there were low correlations (r<0.75) among the analyzed items of dental arch form and the included angles of HIP plane with various occlusal planes. Hence, the excellent parallelism between HIP plane and occlusal plane can be concluded in this study. Using HIP plane as a reference for the orientation of occlusal plane may be recommended.

Texte intégralRésumé :
AbstractThe clinical evaluation of the face is the most important aspect of evaluating patients with dentofacial deformities. The clinical examination is the primary determinant in making a diagnosis and developing a treatment plan. The basic treatment goals are: establishment of orofacial function, ensure stability of results, achieve facial esthetics and to consider the patency of the airway. The systematic clinical examination is divided into five basic evaluations: the frontal view, the profile view, three quarter view, an occlusal assessment and the temporomandibular joint evaluation. The clinical diagnosis is then confirmed with special investigations such as panoramic, lateral and anteroposterior cephalometric radiographs and other investigations as required. A dental, skeletal and soft tissue problem list is then noted and orthodontic and surgical solutions integrated into a final treatment plan. A cephalometric radiographic tracing or a 3D virtual treatment planning system is finally used to measure the planned surgical movements and to visualize the expected treatment results.

Texte intégralRésumé :
Now you have an understanding of the anatomy of the maxilla and mandible, the TMJs, and jaw musculature, we can examine how these structures work together to produce the complex actions involved in the biting and chewing of food. Technically, incision is biting a piece from a larger chunk of food and mastication is the grinding down of that piece into smaller components and mixing them with saliva. Mastication is often used to cover both actions. Box 26.1 briefly compares the anatomy of the human dentition to that of other mammals. As well as knowledge of the TMJ, muscles of mastication, and other muscles used in jaw movements, it is necessary to appreciate some aspects of the static and dynamic relationships of the teeth to understand chewing movements. The first thing to notice is the bigger width of the upper dental arch compared to the lower arch, a condition known as anisognathy. In Figure 26.1A , you can see that the maxillary molars overhang the mandibular teeth by half a cusp width so the buccal cusps of the lower molars and premolars occlude between the buccal and palatal cusps of the maxillary teeth. Observe also that the long axis of the maxillary molars and premolars incline buccally while the corresponding axis of the mandibular teeth incline lingually; the occlusal plane of the posterior teeth is thus curved transversely as illustrated in Figure 26.1A . It would be possible to chew food simply by moving the teeth up and down without any side-to-side movement, but this would be inefficient and not make full use of the cusps on the occlusal surfaces of posterior teeth. However, we can only chew on one side at a time because of the anisognathy of the upper and lower teeth. Due to anisognathic jaw positions, the maxillary anterior teeth are also going to protrude in front of the mandibular anterior teeth. Figure 26.1B illustrates the normal relationships of the anterior teeth. The maxillary incisors overhang the mandibular incisors by about 2–3 mm in the horizontal plane; this is called the overjet. The upper incisors usually have a vertical overhang, the overbite, of about the same amount. As mentioned in Chapter 24 , the mouth at rest is closed by tonic contraction of the muscles of mastication and facial expression.

Texte intégralRésumé :
This chapter reviews T-Scan use in orthodontics from diagnosis to case finishing, and then in retention, while defining normal T-Scan recording parameters for orthodontically-treated subjects versus untreated subjects. T-Scan use in the case-finishing process is also described, which compensates for changes in the occlusion that occur during “post-orthodontic settling,” as teeth move freely within the periodontium to find an equilibrium position when the orthodontic appliances have been removed. T-Scan implementation is necessary because, often, despite there being a post treatment, visually “perfect” angle's Class I relationship established with the orthodontic treatment, ideal occlusal contacts do not result solely from tooth movement. Creating simultaneous and equal force occlusal contacts following fixed appliance removal can be accomplished using T-Scan data to optimize the end-result occlusal contact pattern. The T-Scan software's force distribution and timing indicators (the two- and three-dimensional force views, force percentage per tooth and arch half, the center of force trajectory and icon, the occlusion time [OT], and the disclusion time [DT]), all aid the Orthodontist in obtaining an ideal occlusal force distribution during case-finishing. Fortunately, most orthodontic cases remain asymptomatic during and after tooth movement. However, an occlusal force imbalance or patient discomfort may occur along with the malocclusion that needs orthodontic treatment. Symptomatic cases require special documentation at the baseline, and careful monitoring throughout the entire orthodontic process. The clinical use of T-Scan in these “fragile” cases of patient muscle in-coordination, mandibular deviation, atypical pain, and/or TMJ idiopathic arthritis, are illustrated by several case reports. The presented clinical examples highlight combining T-Scan data recorded during case diagnosis, tooth movement, and in case finishing, with patients that underwent lingual orthodontics and orthognathic surgery, orthodontic treatment using clear aligners, or conventional fixed treatment with a camouflage treatment plan, which require special occlusal finishing (when premolars are extracted in only one arch).

Texte intégralRésumé :
Orthodontics is ‘the specialty of dentistry concerned with growth of the face, the development of dentition, and the prevention and correction of occlusal anomalies. A malocclusion can be defined as ‘a deviation from the ideal that may be aesthetically or functionally unsatisfactory, with a wide range of occlusal traits’. Orthodontics is a constantly evolving specialty, with ever changing principles and techniques continuing to be developed. There has been huge progress in orthodontics in recent times, with changes in the types of brackets, archwire materials, and appliance systems (such as temporary anchorage devices and aligner technology). The key principles of orthodontics date back to 1899 when Edward Angle described ‘the key to a normal occlusion as the anteroposterior relationship between the upper and lower first molars’. In 1972, Lawrence Andrews described ‘six keys to an ideal static occlusion’. This was the basis of early orthodontic treatment planning. Knowledge of craniofacial development and growth is required as a foundation for understanding the aetiology of a patient’s malocclusion, to reach a diagnosis, and to plan orthodontic treatment. A basic understanding of the types of orthodontic appliances is beneficial (mainly fixed appliances, functional appliances, some use of removable appliances, and retainers). In addition to the management of a malocclusion, orthodontic treatment is often required in conjunction with other specialties, including oral and maxillofacial surgery, paediatric and restorative dentistry Key topics discussed in this chapter include: ● Fixed appliances ● Functional appliances ● Removable appliances ● Retention ● Index of treatment need ● Orthodontic assessment and diagnosis ● Cephalometric analysis ● Malocclusion ● Ectopic canines ● Dental anomalies.

Texte intégralRésumé :
Les dernières technologies informatiques ainsi que le développement des imprimantes 3D ouvrent des perspectives intéressantes en terme de diagnostic et de thérapeutique en implantologie (1). Le plan de traitement prothétique doit guider le choix du nombre et du positionnement des implants. Les logiciels de planification implantaire permettent de superposer les fichiers DICOM (Digital Imaging and Communications in Medicine) de limagerie tridimensionnelle issue du CBCT et les données numériques de surface issues d’empreintes optiques ou de la numérisation de modèles conventionnels (2). Les modélisations occlusales peuvent être elles aussi réalisées virtuellement en statique et dynamique via l’utilisation darticulateurs virtuels (3,4). Un guide chirurgical est alors imprimé permettant de positionner les implants selon la planification virtuelle. Dans certains cas, la restauration provisoire peut être prévue à l’avance et mise en place à lissue de lintervention (5,6). Bien quil soit établit que la chirurgie guidée soit plus précise que la chirurgie à main levée (7), son utilisation en pratique quotidienne a été ralentie en grande partie à cause du coût de fabrication élevé. Le développement récent dimprimantes 3D de bureau de haute précision (8,9) et la multiplicité des logiciels de planification implantaire ont permis le développement de la chirurgie guidée. Cependant, à chaque étape du flux numérique, des imprécisions peuvent se cumuler pouvant aboutir à des erreurs de positionnement ayant des conséquences potentiellement graves : proximité avec les racines adjacentes, perforation des racines, lésion nerveuse. La précision des guides chirurgicaux sté- réolithographiques dépend de nombreux paramètres : lempreinte, l’impression du guide, le matériau utilisé, la nature du support, lexpérience du praticien. Les empreintes optiques réalisées avec des scanners intra-oraux de plus en plus puissants présentent de nombreux avantages par rapport aux techniques conventionnelles en terme de rapidité, de précision et de reproductibilité. (10-14). Les guides peuvent être à appui osseux, muqueux, dentaire ou mixte. Une revue systématique de la littérature de Gallardo et coll. en 2017 (15) compare la précision des guides chirurgicaux en fonction du type de support. Cette revue conclut que les guides à appui osseux présentent le plus de déviation au niveau de langle, du point dentrée et de la localisation de lapex de l’implant par rapport aux guides à appuis dentaires. Les guides à appuis muqueux montrent moins de déviation par rapport aux guides à appuis osseux. Les auteurs nont pas trouvé de différence statistiquement significative entre les guides à appuis dentaires et muqueux. Selon L’étude de Cassetta publiée en 2017 (16), lexpérience du praticien influence la précision du positionnement des implants en chirurgie guidée. Un praticien novice en implantologie présente plus de déviation sur le positionnement des implants avec lutili- sation d’un guide chirurgical stéréolithographique quun praticien expérimentée. La chirurgie implantaire guidée reste un outil et nécessite une expérience chirurgicale. Le flux numérique en implantologie peut aujourdhui se réaliser de la prise d’empreintes d’étude à la fabrication de la restauration prothétique implantaire en passant par la conception et l’impression d’un guide chirurgi- cal. Ce flux est une aide précieuse en terme de communication avec le patient mais aussi avec le prothésiste, il permet daugmenter la reproductibilité des résultats et daboutir à une restauration prothétique esthétique et fonctionnelle.
