Academic literature on the topic 'Occlusal vertical dimension'

BACKGROUND: The term decreased occlusal vertical dimension refers to the reduced distance between two anatomical points while the teeth are in a state of occlusion. The development of this situation is about some parafunctional activities of the masticatory system.AIM: To evaluate the value of decreased occlusal vertical dimension in cases with temporomandibular disorder and to follow up the influence of corrective treatment with occlusal splints and definitive prosthetic construction upon the elimination of clinical symptoms.MATERIAL AND METHODS: Eight cases with decreased occlusal vertical dimension accompanied with temporomandibular disorders were treated with an occlusal splint, as part of reversible occlusal treatment. After reducing, or complete elimination of the symptoms related to problems of decreased occlusal vertical dimension, the definitive prosthetic therapy was performed.RESULTS: The mean value of decreased occlusal vertical dimension in our patients is 8.5 mm, and the mean value of therapy time with an occlusal splint in these patients was 3.5 months.CONCLUSION: Occlusal splint is a part of reversible occlusal therapy in cases with decreased occlusal vertical dimension. After reducing the symptoms related to decreased occlusal vertical dimension definitive prosthetic therapy can be done.

The movement of teeth during processing of complete dentures disturbs the harmonious occlusal scheme established at the final wax try-in stage. Aims and objectives: to investigate the effect of RS flask closure on occlusal vertical dimensions of complete dentures. The mean occlusal vertical dimension of complete maxillary and mandibular dentures fabricated by the conventional flask closure were measured and compared with that of dentures fabricated by RS flask closure. Design: A pre-test post-test control group experimental design. Methods: Thirty sets of complete maxillary and mandibular wax trial dentures were randomly assigned to experimental groups. Fifteen sets were assigned to conventional flask closure and the remainder to RS flask closure. Compression molding with a long curing cycle was performed for the processing of the dentures. Pre-processing and post-processing occlusal vertical dimensions were determined. Results: The mean occlusal vertical dimensions of wax trial dentures assigned to either group were similar. The data produced substantial evidence to reject the null hypothesis that the post-processing mean occlusal vertical dimensions of both groups were equal. Conclusion: The occlusal vertical dimensions produced by dentures clamped by the RS flask closure were significantly less than those produced by dentures clamped by the conventional flask closure.

Advanced tooth wear often results in lost vertical dimension and impacts facial aesthetics. Complex restorative treatment can replace the lost tooth structure and improve functional occlusal and facial skeleton parameters. Purpose: The aim of the study is to assess changes in the morphological and functional occlusal parameters of the facial skeleton after prosthetic rehabilitation that increased lost occlusal vertical dimension. Material and Methodology: 50 patients with advanced tooth wear were clinically examined, to assess the degree of wear. Each subject underwent cephalometric analysis, digital occlusal analysis, and electromyographic analysis, of the anterior temporalis, superficial masetter, anterior digastric, and the sternocleidomastoid muscles. Prosthodontic treatment was performed to restore the occlusal vertical dimension of each subject’s occlusion, which was followed by repeating the pretreatment analyses. Pre and post treatment parameters were statistically compared. Results: Pre-treatment cephalometric analysis showed that lost vertical dimension reduced anterior facial height and resulted in small angular skeletal parameters. Post treatment anterior facial height increased from the increased occlusal vertical dimension. The mean value of functional electrical activity during clenching post treatment, increased compared to pretreatment. Conclusion: Increasing the vertical dimension of occlusion improved facial aesthetics by positively affecting facial skeletal angles. The restored occlusal surface morphology changed the pre treatment flat broad occlusal contacts into more point contacts. The increased vertical dimension of occlusion after treatment also increased muscle activity levels over the pretreatment levels after three months period of adaptation.

Introduction. More recent research points out to the existence of a new concept of the technique for locating the neutral zone. The objective of the study was to determine the effect of changing vertical dimension of occlusion, as well as that of the alveolar ridge type, on the neutral zone dimensions. Material and methods. The neutral zone was investigated in two groups of patients, with prominent (the control group) and flat alveolar ridges and it was determined for each patient at 3 heights (the correct, the increased and the decreased vertical dimension of occlusion). It was studied both vertically and horizontally. The width of the neutral zone was measured in different regions. Results. The width of the neutral zone was minimal at the level of the occlusal plane, and it increased gradually as the occlusal plane went down and up, towards the anterior region. Conclusion. No statistically significant difference was found in the width of the neutral zone, between the group of patients with prominent alveolar ridges (the control group), and that with the flat ones. There was, also, no difference at all, at any level of the vertical dimension of occlusion, that could possibly bear statistical significance.

Tooth wear is a common problem seen in population and poses restorative challenge to a dentist as well. Extensive dental procedures are usually required for the treatment of tooth wear associated with loss of occlusal vertical dimension. An overlay removable partial denture provides conservative treatment option for patients with moderate to severe worn down dentition and partial edentulism. It is designed in such a way that some part of denture component also covers the occlusal surface of remaining teeth and replace the remaining teeth to achieve a functionally stable occlusion. This case report is about a patient who was given cast metal overlay upper and lower denture for a correction of lost vertical dimension of occlusion, replacement of few missing teeth and for the prevention from further tooth wear.

La modicación de la dimensión vertical oclusal es un procedimiento que muchas veces es necesario durante los tratamientos complejos de rehabilitación oral para conseguir un esquema oclusal funcio-nal para los pacientes. Esta revisión de la literatura fue hecha sobre las bases de datos: Medline (PubMed), Scopus, Scielo, BSV (Bireme), ISI (Web of Sciencie) y Lilacs utilizando las palabras clave “occlusal vertical dimension”, “altered vertical dimension”, “temporomandibular joint” y “masticatory muscles”. Se puede armar que el manejo de la dimensión vertical oclusal es un procedimiento seguro si se tienen en cuenta ciertas consideraciones de importancia para realizar los tratamientos protésicos y de todas las especialidades odontológicas. Existe información bibliográca relacionada a las consideraciones que se deben tener en cuenta cuando se varía la dimensión vertical oclusal, las cuales son aplicables en el área de rehabilitación oral.

ABSTRACT A decrease in occlusal vertical dimension (OVD) may result from tooth structure loss and extraction of posterior teeth, and it affects the esthetics, function, comfort, and lower facial height (LFH). Rehabilitation of patients with worn dentitions may require increase in OVD and interarch distance to create space for restorative materials, improve esthetics, and develop physiologic occlusion. It is usually advisable to assess esthetics, function, LFH, and response of the stomatognathic system to increased OVD by means of removable or fixed provisional appliances before definitive treatment. The following case report presents the multitude of factors considered in planning amount of OVD increase keeping in view its impact on LFH and facial esthetics, during rehabilitation of a patient with severely attrided dentition.

ABSTRACT Esthetic and functional rehabilitation of severely worn dentition presents a significant challenge to the restorative dentist. The prerequisites in restoring the worn dentition are to understand the determinants of the occlusal vertical dimension and the effects of its alteration on the temporomandibular joint, muscle comfort, bite force, speech and long-term occlusal stability. This clinical report describes a sequential treatment procedure of full mouth rehabilitation of a patient with severe attrition and cervical abrasion of teeth with metal-ceramic restorations and implant supported fixed dental prosthesis after establishing a functional and esthetic vertical dimension and occlusal plane.

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

When a complete denture wearer presents for restorative treatment, one of the most important challenges for the dentist is to determine the optimal occlusal vertical dimension (OVD). Studies have shown that establishing a correct OVD is of paramount importance, and many techniques have been proposed for determining the OVD, including the use of pre-extraction records, phonetics, swallowing, aesthetic appearance, and correlation with finger length. However, there is no universally accepted scientific method for determining OVD in edentulous patients. This literature review investigates the various methods that are in use and considers which may be most suitable or advisable for the prosthetic dentist. Based on the literature available, no single technique stands out as significantly better than others and the dentist should ideally use more than one technique to achieve the best results.
Quando um usuário de prótese total removível se apresenta para tratamento restaurador, um dos desafios mais importantes para o dentista é determinar a dimensão vertical de oclusão ideal (DVO). Estudos demonstraram que a determinação de uma DVO correta é de extrema importância. Muitas técnicas foram propostas para determinar a DVO, incluindo a utilização de registos de pré-extração, fonética, deglutição, aparência estética e a correlação com o comprimento dos dedos. No entanto, não existe um método científico universalmente aceito para determinar a DVO em pacientes edêntulos. Esta revisão literária investiga os vários métodos que estão em uso e considera quais podem ser mais adequados ou aconselháveis para o dentista protético. Com base na literatura disponível, nenhuma técnica se destaca como significativamente melhor do que outras e o dentista deve idealmente usar mais do que uma técnica para alcançar os melhores resultados.

To determine an optimal occlusal vertical dimension (OVD) is important in fabricating complete denture. Many methods have been proposed to establish a proper occlusal vertical dimension, such as using the rest of vertical dimension, swallowing methods, cephalometric radiography, speaking methods, and facial analysis. However, none of them has been widely recognized as the optimal. In this study a new approach using ultrasound was tested with the aim to determine scientifically the optimal occlusal vertical dimension. 10 volunteers (average 26.6) were enclosed to this study. The occlusal vertical dimension of each volunteer was raised by a custom made splint with the height of 3, 6, 9 minimeters respectively. The swallowings of every volunteer in different vertical dimensions were examined by the computer-aided B mode plus M mode ultrasonography combined with the cushion scanning technique. The result showed that no significant difference to total-duration and amplitude of swallowing at 3mm increasing height of OVD. The total-duration and amplitude of swallowing at 6mm increasing height of OVD were significantly higher than control group at immediate placement. (p=0.0443 and p=0.0098) Moreover, The duration of swallowing at 9mm increasing height of OVD were significantly higher than control group at immediate placement,1 and 3 hours later.(p=0.0272, p=0.0174, p=0.0173) The amplitude of swallowing at 9mm increasing height of OVD were also significantly higher than control group at immediate placement,1、3 and 6 hours later(p=0.0039, p=0.0038, p=0.0018, p=0.0286).Increasing occlusal vertical dimension would change the swallowing duration and amplitude. Furthermore, tongue could gradually adapt to the different occlusal vertical dimensions.

Introduction: the occlusal vertical dimension (OVD) refers to the length of the face as determined by the amount of separation between two points of the jaws: one fixed point in the maxilla and another mobile point in the mandible, when the teeth are in maximum intercuspation. The OVD is often diminished in patients with severe tooth wear. Many of these patients come to the clinic due to sensibility and / or pain, difficulty chewing and eating, or cosmetic problems, depending on the degree of dental wear. According to the severity of wear, the most appropriate technique is chosen for each patient as well as the material that suits best. Quite often the rehabilitation will require the restoration of the OVD. Aims: The objectives of this thesis were to make a literature review on the different techniques used to restore the OVD and rehabilitate the worn dentition in patients with severe dental wear, and to compare the long-term results of each approach. Methodology: A literature review was done using online data bases such as Cochrane, ScienceDirect, PubMed and MedLine. The key-words used were severe tooth wear, full-mouth adhesive rehabilitation, restoration of Occlusal Vertical Dimension and minimally invasive dentistry. The search included publications in peer-reviewed indexed papers published between 2000 and 2019, in English and Spanish. Of the 3657 articles found, 3590 were excluded for not meeting the predefined requirements and 67 articles were included in the study. Conclusion: Full mouth rehabilitation based on full crown coverage does not appear to be the treatment of choice for patients with severe wear. Instead, a full mouth adhesive rehabilitation is recommended, this treatment approach makes the dentist's job easier during planning and execution and also because it is more conservative.
Introdução: A Dimensão Vertical Oclusal (OVD) refere-se ao comprimento da face determinado pela quantidade de separação entre dois pontos da mandíbula: um ponto fixo na maxila e outro ponto móvel na mandíbula, quando os dentes estão no máximo intercuspidação. O OVD é frequentemente diminuído em pacientes com desgaste dentário severo. Muitos desses pacientes procuram a clínica devido à sensibilidade e/ou dor, dificuldade de mastigar e comer ou problemas estéticos, dependendo do grau de desgaste dentário. De acordo com a gravidade do desgaste, escolhe-se até a técnica mais adequada para cada paciente e também o material que melhor se adapta. Muitas vezes, a reabilitação exigirá a restauração do OVD. Objectivos: Os objetivos desta tese foram fazer uma revisão da literatura sobre as diferentes técnicas utilizadas para restaurar o OVD e reabilitar a dentição desgastada em pacientes com desgaste dentário severo, e comparar os resultados a longo prazo de cada abordagem. Metodologia: Foi realizada uma revisão da literatura em bases de dados online como Cochrane, ScienceDirect, PubMed e MedLine. As palavras-chave utilizadas foram desgaste dentário severo, habilitação adesiva de boca inteira, restauração da Dimensão Vertical Oclusal e odontologia minimamente invasiva. A busca incluiu publicações em artigos indexados revisados por pares publicados entre 2000 e 2019, em inglês e espanhol. Dos 3657artigos encontrados, 3590 foram excluídos por não atenderem aos requisitos pré-definidos e 67 artigos foram incluídos no estudo. Conclusão: A reabilitação bucal total com base na cobertura total da coroa não parece ser o tratamento de escolha para pacientes com desgaste severo. Em vez disso, uma reabilitação adesiva de boca completa é recomendada, pois essa abordagem de tratamento facilita o trabalho do dentista durante o planeamento e execução e também porque é mais conservadora.

La DVO suele estar disminuida en pacientes com desgaste dental severo. Muchos de estos pacientes acuden a la clínica por sensibilidady / odolor, dificultad para masticar y comer, o problemas estéticos, según el grado de desgaste dental Según la severidade del desgaste, se elige la técnica más adecuada para cada paciente, así como el material que mejor se adapta. Muy a menudo, la rehabilitación requerirá la restauración del OVD. Objetivos:Los objetivos de esta tesis fueron hacer una revisión de la literatura sobre las diferentes técnicas utilizadas para restaurar el OVD y reabilitar la dentición desgastada en pacientes com desgaste dental severo, y comparar los resultados a largo plazo de cada abordaje. Metodología: Se realizó una revisión de la literatura utilizando bases de datos online como Cochrane, ScienceDirect, PubMed y MedLine. Las palabras clave utilizadas fueron desgaste dental severo, habilitación adesiva de boca completa, restauración de la dimensión vertical oclusal y odontologia minimamente invasiva.

De 3657 artículo encontrados, 3590 fueron excluídos por no cumplir com los requisitos predefinidos y 67 se incluyeron artículos en el estudio. Conclusión: La rehabilitación bucal completa basada en la cobertura total de la corona no parece ser el tratamento de elección para pacientes com desgaste severo. En cambio, se recomenda una rehabilitación com adesivo de boca completa, ya que este enfoque de tratamento facilita el trabajo del dentista durante la planificación y ejecución y también porque es más conservador.

It is generally agreed that the most troublesome procedure during the fabrication of complete dentures is the measurement of the Vertical Dimension at rest. The aim of this study was to test the reliability and validity of a new instrument called the Facial Anthropological Device (FAD). The measurements recorded were compared to the Willis gauge (being the gold standard) and dividers, which are mechanical aids used to quantify lower third facial height during denture construction. This thesis presents data on 35 edentulous and 35 dentate patients in the age range of 30 to 70 years, who presented at the University of the Western Cape Dental faculty.The FAD incorporates a ‘spirit‐level’ and uses more anatomical landmarks than any other measuring device noted in the literature. It measures facial landmarks in the midline and is not only used to measure the vertical dimension of the face, but with further research, may also be used in forensic studies. The Willis gauge is designed to measure the distance from the lower border of the septum of the nose to the lower border of the chin, and the distance from the outer canthus of the eye to the corner of the relaxed lip with the teeth in occlusion. The dividers measures two arbitrary points on the face.The study showed that the FAD was most similar to the Willis gauge where reliability and reproducibility was compared. There were no statistically significant differences (P > 0.05) between the two devices.The FAD has shown to be a reliable and valid instrument that could be used to measure facial vertical dimension in the edentulous as well as dentate patients, however with some modifications to its design.

A etiologia das disfunções temporomandibulares é controversa e resulta de uma combinação de factores de risco, incluindo factores ambientais, traumáticos, comportamentais, psicológicos e oclusais. Vários autores alegaram que uma alteração na dimensão vertical da oclusão pode afetar a função, o conforto e a estética do paciente (Goiato et al., 2013). A etiologia de uma alteração da dimensão vertical da oclusão é múltipla, e muitas investigações científicas nesta área propõem várias técnicas para determinar a dimensão vertical da oclusão, mas nenhuma parece destacar-se quanto à fiabilidade e precisão. O objetivo deste trabalho é discutir a correlação entre a alteração da dimensão vertical da oclusão e as disfunções temporomandibulares. De um total de 313 artigos relacionados com este tópico e encontrados através do PubMed e Google Scholar, foram selecionados 62 artigos para uma leitura completa, incluindo 18 estudos sobre a relação entre dimensão vertical da oclusão e as disfunções temporomandibulares. Destes, 11 estudos mostraram uma correlação positiva entre elas e nos restantes 7 estudos nenhuma associação é relatada.
The etiology of temporomandibular disorders is controversial and results from a combination of risk factors, including environmental, traumatic, behavioural, psychological and occlusive factors. Several authors have argued that an alteration in the vertical dimension of occlusion can affect the patient's function, comfort and aesthetics (Goiato et al., 2013). The etiology of a change in the vertical dimension of the occlusion is multiple, and many scientific investigations in this area propose various techniques for measuring vertical dimension of occlusion, but none seems more accurate or reliable than another. The aim of this work is to discuss the correlation between vertical dimension of occlusion change and temporomandibular disorders. From a total of 313 articles related to this topic and found through PubMed and Google Scholar, 62 articles were selected for a complete reading, including 18 studies on the relationship between vertical dimension of occlusion and temporomandibular disorders. 11 studies found a positive correlation between them , while in the remaining 7 studies no association is reported.

Review question / Objective: The aim of this systematic review is to synthesize the scientific evidence that evaluates fatigue and fracture resistance, survival, and stress distribution, of composite resin CAD/CAM and ceramic CAD/CAM occlusal veneers in posterior teeth with severe occlusal wear. Condition being studied: Currently there is an increase in cases of dental wear, due to several factors such as: excessive consumption of carbonated drinks, a diet high in acids, gastric diseases, anorexia, bulimia, dental grinding, use of highly abrasive toothpastes, or a combination of these(9) (10) (11) (12); which affect the patient in several aspects: loss of vertical dimension, sensitivity due to the exposure of dentin, esthetics, affectation of the neuromuscular system(11) (13) (14). With the advent of minimally invasive dentistry, occlusal veneers have been found to be a valid option to rehabilitate this type of cases and thus avoid greater wear of the dental structure with full coverage restorations. Sometimes when performing a tabletop it is not necessary to perform any preparation, thus preserving the maximum amount of dental tissue(3) (6) (15). Due to the masticatory load either in patients without parafunction where the maximum masticatory force is approximately 424 N for women and 630 N for men or in those who present parafunction where the maximum bite force can vary from 780 to 1120N(7), it is necessary that the occlusal veneers support that load which makes indispensable a compilation of studies investigating both fatigue and fracture resistance and the survival rate of occlusal veneers in different materials and thicknesses.
