Abstract:

O conhecimento da anatomia microcirúrgica do hipocampo tem importância fundamental na cirurgia da epilepsia do lobo temporal. Uma das técnicas mais utilizadas na cirurgia da epilepsia é a técnica de Niemeyer. OBJETIVO: Descrever em detalhes a anatomia do hipocampo e mostrar uma técnica na qual pontos de referências anatômicos pré-operatórios visualizados na RNM são usados para guiar a corticotomia. MÉTODO: Foram utilizados 20 hemisférios cerebrais e 8 cadáveres para dissecções anatômicas microcirúrgicas do lobo temporal e hipocampo para identificação e descrição das principais estruturas do hipocampo. Foram estudados prospectivamente 32 pacientes com epilepsia do lobo temporal refratários ao tratamento clínico submetidos a amígdalo-hipocampectomia seletiva pela técnica de Niemeyer três parâmetros anatômicos foram mensurados na RNM pré operatória e transferidos para o ato cirúrgico. RESULTADOS: O hipocampo foi dividido em cabeça, corpo e cauda e sua anatomia microcirúrgica descrita em detalhes. As medidas adquiridas são apresentadas e discutidas. CONCLUSÃO: A complexa anatomia do hipocampo pode ser entendida de uma forma tridimensional durante dissecções microcirúrgicas. As medidas pré-operatórias mostraram-se guias anatômicos úteis para corticotomia na técnica de Niemeyer.

L’accélération du déplacement dentaire orthodontique par corticotomie alvéolaire est bien décrite dans la littérature. Elle se traduit par un phénomène d’ostéopénie transitoire, baptisé « phénomène d’accélération régionale » par Frost. Ce mécanisme biologique a été décrit via des études animales et humaines. Cependant, d’autres effets intéressants en pratique orthodontique sont associés aux corticotomies alvéolaires : augmentation de l’amplitude des mouvements dentaires, diminution des résorptions radiculaires et augmentation de stabilité post-traitement orthodontique.

Abstract:

Purpose: Understanding the effects of different corticotomy designs on the velocity of maxillary canine retraction. Materials and Method: The 3-dimensional model of maxillary dentition was constructed and 3 corticotomy designs were compared with the conventional approach of canine retraction. 4 models were constructed for the present study: 1 with no corticotomy cuts (model 1), 1 with vertical cuts on both buccal and palatal side (model 2), other with cuts only on buccal side (model 3), and 1 with circular holes (model 4). Stress intensity and force distribution were evaluated after applying 150 gm of orthodontic forces on maxillary canine. Results: Models with corticotomy approaches exhibited approximately twice the displacement when compared with conventional noncorticotomy procedure. The stresses were mainly concentrated on the distal side of the canine in all the models. The rate of canine retraction was the highest in model with buccal and palatal corticotomy compared to other designs. Conclusions: Corticotomies help orthodontists to alter the biomechanical responses of dentoalveolar structures during maxillary canine retraction and accelerate tooth movement. Clinically, buccal corticotomy is a better choice for the patients as it is less traumatic and more acceptable to patients.

Abstract:

Corticotomy-assisted and osteotomy-assisted tooth movement involves surgical incisions through the alveolar bone. To ascertain whether teeth move by distraction osteogenesis or by regional accelerated phenomenon (RAP), we randomly assigned 30 Sprague-Dawley rats to one of 5 experimental groups: corticotomy alone, corticotomy-assisted tooth movement, osteotomy alone, osteotomy-assisted tooth movement, or tooth movement alone. Each animal was imaged by microtomography immediately after surgery, after 21 days, and after 2 months. After 21 days, regional accelerated phenomenon was observed in the alveolar bone of the corticotomy-treated animals and distraction osteogenesis in the osteotomy-assisted tooth movement animals. Pixel count data were analyzed by nested ANOVA for 5 experimental groups, split-mouth controls, 3 levels along the root, and 5 sites per level. The most demineralized sites after 21 days differed for each of the experimental groups. Our study indicates that osteotomies and corticotomies induce different alveolar bone reactions, which can be exploited for tooth movement.

OBJETIVO: Descrever a técnica de transporte ósseo parietal para tratamento de falha óssea parcial, e descrever o resultado clínico e radiográfico de uma série de pacientes tratados por esta técnica. CASUÍSTICA E MÉTODO: tratamos nove pacientes portadores de lesão óssea parcial, sendo seis localizada na tíbia e três no fêmur. Todos apresentavam lesão infectada, acompanhada de pseudo-artrose. O procedimento iniciou-se com estabilização do segmento ósseo com fixador externo, seguido de corticotomia parietal, em osso sadio adjacente à falha, para criar o fragmento que foi transportado. Este fragmento foi transfixado por fios olivados, que conectados às hastes sulcadas permitiam o transporte ósseo. Em dois pacientes os fragmentos utilizados eram de osso adjacente (fíbula), transportados para a tíbia em direção da tíbia. A latência, velocidade e ritmo de distração foram os preconizados por Ilizarov. RESULTADOS: a infecção e a pseudo-artrose foram curadas em todos os casos, com preenchimento da falha óssea. As complicações encontradas foram infecção nos orifícios dos fios na pele e regenerado hipotrófico. CONCLUSÃO: o tratamento da falha óssea parcial pelo transporte ósseo parietal determinou solução do processo infeccioso, com consolidação da pseudo-artrose e preenchimento da falha óssea.

Abstract:

ABSTRACT Aim By using the finite element method (FEM), this study aimed to evaluate the effect of different corticotomy formats on the distribution and magnitude of stress on the periodontal ligament (PDL) during retraction of the maxillary canine. Materials and methods A geometric model of the left hemi-jaw was created from computed tomography scan images of a dry human skull and loads were administered during distalization movement of the canine. Three trials were performed: (1) without corticotomy, (2) box-shaped corticotomy and perforations in the cortical bone of the canine (CVC) and (3) CVC and circularshaped corticotomy in the cortical bone of the edentulous space of the first premolar. Results There was no difference in stress distribution among the different corticotomy formats. Conclusion Different corticotomy formats used to accelerate orthodontic tooth movement did not affect stress distribution in the PDL during canine retraction. Clinical significance From a mechanical perspective, the present study showed that the stress distribution on the PDL during canine retraction was similar in all the corticotomy formats. When using the Andrews T2 bracket, the PDL presented the highest levels of stress in the middle third of the PDL, suggesting that the force was near the center of resistance. Also, as bone weakening by corticotomies did not influence stress distribution, the surgical procedure could be simplified to a less aggressive one, focusing more on inflammatory cellular stimulation than on bone resistance. A simpler surgical act could also be performed by most orthodontists in their practices, enhancing postoperative response and reducing patient costs.

Abstract:

Introduction : L’orthodontie chez l’adulte doit s’adapter à certaines particularités notamment liées à la diminution ou à l’absence de croissance, ainsi qu’à la prévalence des atteintes parodontales dans cette population. Cette revue de la littérature a pour objectifs d’évaluer les effets des corticotomies alvéolaires sur l’accélération ou la facilitation des déplacements dentaires selon les différents types de mouvements orthodontiques, de comparer les résultats obtenus par technique classique avec ceux obtenus par piézocision et d’analyser leur impact sur les tissus parodontaux sur le long terme. Matériels et méthodes : La recherche a été réalisée avec les bases de données Medline, Embase et Cochrane, à partir de janvier 2000. Chaque étude, sélectionnée par son titre et son résumé, a ensuite été évaluée à travers son contenu complet. Au total, 65 études ont été incluses. Résultats : Toutes les études ont montré que les corticotomies facilitent et accélèrent temporairement le déplacement dentaire orthodontique avec des complications minimes. Aucune lésion parodontale, perte de vitalité pulpaire ou résorption radiculaire sévère n’a été rapportée. Discussion : Seules quelques études ont examiné des groupes témoins traités par orthodontie conventionnelle. La corticotomie permet l’accélération temporaire des déplacements dentaires orthodontiques et la piézocision, moins invasive et réalisée dans certaines indications, allège quant à elle les suites post-opératoires. Cependant, le fait que l’utilisation de corticotomies alvéolaires diminue significativement le temps de traitement reste incertain, en raison de l’absence de données significatives. Davantage d’études prospectives randomisées sont nécessaires afin d’analyser plus précisément la diminution du temps de traitement global, l’amélioration du contexte parodontal et de la stabilité des résultats du traitement orthodontique sur le long terme suite aux corticotomies alvéolaires.

Abstract:

Background and Objectives The average orthodontic treatment time for extraction therapy is 31 months. One of the main disadvantages of orthodontic treatment is time. Alveolar corticotomies have been used in conjunction with orthodontics to reduce the treatment time by increasing the rate of tooth movement. Concerns about the possible risks of corticotomy procedure have led to the modification of this technique. Germeç et al. reported a case treated by their modified corticotomy technique and noted reduced treatment time without any adverse effects on the periodontium and the vitality of teeth with their new conservative corticotomy technique. This study was undertaken to clinically evaluate the efficacy of the aforesaid technique. Materials and Methods A split-mouth study design was carried out to compare the rate of maxillary canine movement with and without modified corticotomy facilitated orthodontic treatment in 10 patients requiring maxillary first premolar extractions. The modified corticotomy procedure was performed on the maxillary arch unilaterally. The upper arch was immediately activated bilaterally after surgical procedure using equal orthodontic forces for retraction of the maxillary canines. The amount of tooth movement was recorded at an interval of every month till the completion of canine retraction. The rate of canine movement on experimental and control site was compared. The patients were followed for 6 months to check the occurrence of undesired effects such as root resorption, periodontal damage and loss of vitality of teeth on the experimental side. Results Higher mean velocity was observed in canines with modified corticotomy facilitated retraction compared to conventionally retracted canines; with the difference in mean velocity between the two groups was found to be clinically significant as well as statistically significant (P < 0.001). Interpretation and Conclusion The results suggested that modified corticotomy technique serves as an effective and safe way to accelerate orthodontic tooth movement, without adversely affecting the periodontium, root resorption, and the vitality of the teeth, as concluded by clinical and radiographic examination.

Abstract:

ABSTRACT Objective: To compare the histological responses in corticotomy- and corticision-assisted tooth movement. Materials and Methods: Ninety Wistar rats were divided into three groups: C (control—tooth movement only), CT (tooth movement + corticotomy), and CI (tooth movement + corticision). Surgeries were performed on the vestibular and lingual cortical bone of the maxillary first molar. Tooth movement was carried out with nickel-titanium closed coil springs having a force of 30 g. The rats were sacrificed at 3, 14, and 28 days. To evaluate the number of osteoclasts and amount of root resorption, a tartrate-resistant acid phosphatase stain was used. Hematoxylin and eosin staining was performed for areas of hyalinization, and the organic bone matrix was stained with picrosirius. Results: The CT group showed a greater number of osteoclasts than did the C group on day 3 (P < .05). At the same time point, the CT and CI groups showed a delayed onset of organic bone matrix remodeling and a lower incidence of root resorption than did the C group (P < .05). There were also fewer hyalinization areas in the CI group than in the C group on day 3 (P < .05). Conclusions: Corticotomy effectively increased bone resorption during the early stages of tooth movement, but this increase was not observed for corticision. The surgical procedures did not accelerate organic bone matrix remodeling. Corticotomies and corticisions decreased the risk of root resorption only during the early stages of movement. Corticision reduced the level of hyalinization, while corticotomy did not.

Abstract:

Introduction : La durée des traitements orthodontiques chez l’adulte reste une barrière pour ces patients. Différentes techniques notamment chirurgicales ont été développées afin de remédier à ce paramètre. La technique classique de corticotomie est efficace pour réduire le temps de traitement, mais se révèle être très invasive, générant des suites post-opératoires importantes. Matériels et méthodes : Des techniques minimalement invasives, sans élévation de lambeaux muco-périostés, ont été mises au point : corticision, micro-ostéoperforations, piézoponctures et piézocision. Résultats : La piézocision se révèle être le meilleur compromis pour accélérer le déplacement dentaire en respectant un protocole chirurgical et orthodontique bien spécifique. Elle permet également l’adjonction de biomatériaux dans les cas de déhiscences et/ou fenestrations osseuses vestibulaires associées à un encombrement modéré à sévère. Conclusion : Selon les résultats actuels, les techniques minimalement invasives de corticotomies peuvent être considérées comme un nouvel outil thérapeutique dans l’accélération du déplacement dentaire orthodontique.

ABSTRACT In this article, a review of the literature regarding the use of selective alveolar corticotomies (SAC) combined with orthodontic treatment was conducted, and the results of its use in a patient with overerupted maxillary 1st molars are described. Adequate intrusion was obtained within a short period of time, the protocol avoided the necessity of removal of sound tooth structure for crown lengthening, endodontic treatment, and full crown prosthetic restorations. Therefore, the obtained results indicate that SAC/orthodontic use is efficient in the intrusion of overerupted 1st molars and suggest its potential use in the treatment of other malocclusions.

Abstract:

Corticotomy is an effective approach in accelerating orthodontic tooth movement (OTM) in clinical treatment. Corticotomy causes regional acceleratory phenomenon (RAP) in the alveolar bone of surgical sites. However, the molecular mechanism of RAP after corticotomy remains unclear. Herein, we established a mouse model to study the biomechanical interfaces of corticotomy-assisted OTM and to investigate the histological responses and underlying cellular mechanism. A total of 144 male C57BL/6 mice were randomly assigned into four groups: corticotomy alone (Corti), sham operation (Sham), corticotomy with tooth movement (Corti + TM), and sham operation with tooth movement (Sham + TM). Nickel–titanium orthodontic springs were applied to trigger tooth movement. Mice were sacrificed on Post-Surgery Day (PSD) 3, 7, 14, 21, and 28 for radiographic, histological, immunohistochemical, and molecular biological analyses. The results reveal that corticotomy significantly promoted alveolar bone turnover and periodontal tissue remodeling. During orthodontic tooth movement, corticotomy significantly promoted osteogenic and proliferative activity, accelerated tooth movement, and eliminated root resorption by upregulating Wnt signal pathway.

Abstract:

Corticotomy-facilitated orthodontics is a clinical treatment modality comprising the application of conventional orthodontic forces combined with selective decortication of the alveolar process of the bone, which generates a localized process of bone remodeling (turnover) that enables accelerated orthodontic tooth movement. Compared with conventional orthodontic treatment, corticotomy-facilitated orthodontics is associated with reduced treatment time and reduces the frequency of apical external root resorption; however, this modality increases morbidity and financial costs. Although the clinical outcomes of corticotomy-facilitated orthodontics appear favorable, no results of evidence-based investigations of long-term outcomes are available in the literature, and the long-term effects of corticotomy-facilitated orthodontics on the teeth and periodontium are unclear. This narrative review discusses the biological events associated with corticotomy-facilitated orthodontics. Authoritative articles found in relevant databases were critically analyzed and the findings were integrated and incorporated in the text.

Introduction : l'objectif de cette étude est d'évaluer l'efficacité de la corticotomie alvéolaire sur la vitesse du recul de la canine supérieure comparé au traitement conventionnel. Matériel et méthode : L'échantillon était constitué de 30 patients avec un âge moyen de 21 ± 2 ans dont le traitement orthodontique nécessitait le recul des canines supérieures après extraction des premières prémolaires supérieures. Les sujets étaient répartis en deux groupes, l'un recevant un traitement orthodontique assisté par corticotomie alvéolaire, l'autre recevant un traitement conventionnel. La vitesse de recul de la canine supérieure a été évaluée en mesurant la distance entre la canine et la deuxième prémolaire supérieure dans les deux groupes, à 2 mois puis à 4 mois du recul canin. Les résultats ont révélé que cette vitesse était significativement plus élevée dans le groupe expérimental comparé au groupe contrôle et ce deux fois plus à deux mois du recul canin, puis diminuant à 1,25 fois plus élevée à 4 mois. Conclusion : la corticotomie alvéolaire accélère le déplacement dentaire lors du recul des canines supérieures.

Abstract: Introduction: Alveolar corticotomy is a surgical procedure used to increase the velocity of tooth movement. Objective Identify histological evidence of the effect of corticotomy on orthodontic movement in rats. Material and method Forty-five Wistar rats (Rattusnorvegicus Albinus) were equally divided into three groups: Control Group (CG) - no tooth movement or corticotomy; Movement Group (MG) - tooth orthodontic movement only; and Corticotomy and Movement Group (CMG) - tooth orthodontic movement surgically assisted by corticotomy. In the CMG, surgical procedures consisted in an incision in the palatal, reaching from the mesial to the distal regions of the maxillary right first molar. Tooth movement in the MG and CMG was applied with coil spring force of 40 gF from the maxillary right first molar to the maxillary right incisor. The rats were sacrificed at days 1, 3, and 7, and histological sections were performed to evaluate the counting of osteoblasts and osteoclasts throughout the areas of tension and pressure. Result Histological analysis showed that the CMG presented better cell response to bone neoformation compared with that of the other groups. Greater proliferation of osteoclasts was observed in areas of pressure on day 3, resulting in increased reabsorption, whereas greater proliferation of osteoblasts was observed in areas of tension on day 1, indicating increased bone formation. Conclusion Differences between the treated groups occurred only in the initial period of tooth movement. Therefore, the changes caused by corticotomy are not significant in orthodontic movement to justify this invasive procedure.

Abstract:

ABSTRACT Objectives: To evaluate the amount of hyalinization and root resorption after application of light and heavy forces during corticotomy-assisted tooth movement. Materials and Methods: Forty-eight male Wistar rats were used. Eight animals were the control group (day 0). The other 40 animals were randomly divided into two groups using the split-mouth technique: (1) corticotomy combined light force (CLF) and (2) corticotomy combined heavy force (CHF). Nickel-titanium closed coil springs that generated 10 g (light force) and 50 g (heavy force) were used for maxillary first molar movement. three-dimensional root volume was evaluated at 0, 14, and 28 days. Percent hyalinization was analyzed at 0, 3, 7, 14, 21, and 28 days by histomorphometric analysis. Results: The CHF group showed significantly lower cervical root volume than the CLF group at 28 days. Compared with day 0, the CHF group showed significantly less root volume in both distobuccal and distopalatal roots at 28 days. The hyalinization percentages in the CHF group were significantly higher than the CLF group at days 3 and 21. Conclusions: Heavy force combined with corticotomy produced more periodontal ligament hyalinization and root resorption than the light force combined with corticotomy.

Abstract:

El propósito de esta revisión es contribuir a la optimización de la toma de decisiones basada en evidencia científica que explique cómo la corticotomía ayuda en la aceleración del movimiento dentario y determinar si las ventajas son mayores que los riesgos quirúrgicos al que conlleva la técnica. La corticotomía es definida como la intervención quirúrgica limitada a la porción cortical del hueso alveolar por lo que a diferencia de una osteotomía el procedimiento de corticotomía apenas penetra el hueso medular, tanto por la zona bucal y lingual; no obstante, es un método invasivo que requiere la selección correcta del paciente y a su vez informarlo de las condiciones post operatorias y los potenciales riesgos de la cirugía debido a que estimula el proceso de regeneración ósea a través de injurias quirúrgicas controladas, lo que conlleva a acelerar el movimiento dentario durante el tratamiento ortodóntico con activaciones menos prolongadas. También es una técnica que puede reducir el tiempo del tratamiento ortodóntico de un tercio a un cuarto de la duración típicamente requerida, acelerando el movimiento dentario durante los dos primeros meses después de la intervención y los efectos a largo plazo indican estabilidad.

Abstract:

Purpose: This systematic review compares the clinical and radiographic outcomes for patients who received only a corticotomy or periodontal accelerated osteogenic orthodontics (PAOO) with those who received a conventional orthodontic treatment. Methods: An electronic search of four databases and a hand search of peer-reviewed journals for relevant articles published in English between January 1980 and June 2021 were performed. Human clinical trials of ≥10 patients treated with a corticotomy or PAOO with radiographic and/or clinical outcomes were included. Meta-analyses were performed to analyze the weighted mean difference (WMD) and confidence interval (CI) for the recorded variables. Results: Twelve articles were included in the quantitative analysis. The meta-analysis revealed a localized corticotomy distal to the canine can significantly increase canine distalization (WMD = 1.15 mm, 95% CI = 0.18–2.12 mm, p = 0.02) compared to a conventional orthodontic treatment. In addition, PAOO also showed a significant gain of buccal bone thickness (WMD = 0.43 mm, 95% CI = 0.09–0.78 mm, p = 0.01) and an improvement of bone density (WMD = 32.86, 95% CI = 11.83–53.89, p = 0.002) compared to the corticotomy group. Conclusion: Based on the findings of the meta-analyses, the localized use of a corticotomy can significantly increase the amount of canine distalization during orthodontic treatment. Additionally, the use of a corticotomy as a part of a PAOO procedure significantly increases the rate of orthodontic tooth movement and it is accompanied by an increased buccal bone thickness and bone density compared to patients undergoing a conventional orthodontic treatment.

Abstract:

Objectives: The aim of the study was to evaluate and compare the rate of maxillary canine retraction in cases with modified corticotomy versus without modified corticotomy. Clinical interventional study. Split mouth design was used. Materials and Methods: A sample size of ten patients and 20 sites were selected within the age group of 18–35 years following all criteria of the study. Before orthodontic leveling and alignment, upper first premolar extraction was carried out under local anesthesia. Pre-treatment OPG and IOPA were taken in relation to the maxillary canine and maxillary second premolar teeth. One extraction side was considered as the experimental site and contralateral side as control. Leveling and alignment were started with wire sequence. After modified corticotomy procedure, the canine retraction was started with 8 mm NiTi closed coil spring. The amount of tooth movement was recorded with the help of a Digital Vernier Caliper at an interval of 1 month till the completion of canine retraction. Results: Paired t-test showed higher mean velocity of tooth movement in modified corticotomy side (1.07 ± 0.25) as compared to the conventional side (0.91 ± 0.24), (P < 0.001). Conclusion: The modified corticotomy technique serves as an effective treatment modality for adults seeking orthodontic treatment with increased rate of orthodontic canine retraction.

Abstract:

Alveolar augmented corticotomy is effective in accelerating orthodontic tooth movement, but the effect only lasts for a relatively short time. Therefore, the purpose of this study was to investigate the underlying biology of the immediate periodontal response to orthodontic tooth movement after a corticotomy with alloplastic bone grafts. The results demonstrated that measurable tooth movement began as early as 3 days after the intervention in beagle dogs. Based on the results and histological findings, augmented corticotomy-facilitated orthodontic tooth movement might enhance the condition of the periodontal tissue and the stability of the outcomes of orthodontic treatment.

Abstract:

ABSTRACT Objective: To describe an orthodontic treatment that combines an esthetic approach (clear aligners) with surgery (alveolar corticotomy). Materials and Methods: A patient with moderate dental crowding and Class I skeletal and molar relationships was selected. Orthodontic records of the patient were taken. Periodontal indexes, oral health–related quality of life (OHRQoL), and treatment time were evaluated. After we reflected a full-thickness flap beyond the teeth apices, the cortical bone was exposed on the buccal aspect and a modified corticotomy procedure was performed. Interproximal corticotomy cuts were extended through the entire thickness of the cortical layer, just barely penetrating into medullary bone. Orthodontic force was applied on the teeth immediately after surgery. Results: Total treatment time was 2 months. Periodontal indexes were improved after correction of crowding. A deterioration of OHRQoL was limited to 3 days following surgery. Conclusion: This case report may encourage the use, limited to selected cases, of corticotomy associated with clear aligners to treat moderate crowding.

Abstract:

Introduction : Le but de cet article est de montrer l’intérêt de l’utilisation de la technique de déplacements dentaires accélérés par corticotomie dans le cas de patients présentant une occlusion de classe III, avec une crête alvéolaire fine, allant bénéficier d’une chirurgie orthognathique. Méthode : Nous avons sélectionné deux patients adultes pour lesquels la malocclusion de classe III devait être décompensée avant chirurgie de recul mandibulaire. La première patiente a été traitée par déplacement dentaire accéléré par corticotomie et technique de décompensation orthodontique classique, la seconde patiente par déplacement dentaire accéléré par corticotomie et décompensation orthodontique à l’aide d’ancrage squelettique temporaire en association avec une membrane de régénération tissulaire guidée. Une décortication alvéolaire sélective est effectuée à l’aide d’une fraise ronde à vitesse lente et une piézochirurgie au niveau du groupe incisivo-canin mandibulaire. Après hémostase, un greffon osseux est placé sur la zone de décortication. Au niveau de la crête alvéolaire extrêmement fine, un système rigide est mis en place pour immobiliser le greffon. Les forces orthodontiques sont appliquées dès la cicatrisation du lambeau, pour initier le déplacement dentaire accéléré. Résultats : Dans les deux cas, le déplacement dentaire accéléré a été initié et a permis de déplacer les dents du secteur incisivo-canin mandibulaire dans la position requise pour la chirurgie orthognathique. Avec l’imagerie préopératoire en 3D, on peut noter des déhiscences alvéolaires au niveau de la face antérieure des dents symphysaires. L’imagerie postopératoire montre une couverture radio-opaque des racines dénudées. Conclusion : La technique de déplacements dentaires accélérés par corticotomie est une méthode sûre et efficace pour permettre la décompensation alvéolaire pré-chirurgicale au niveau des dents symphysaires de ces patients. La combinaison de cette technique avec l’utilisation d’ancrage squelettique temporaire et de greffe osseuse facilite le déplacement dentaire dans des cas de dentures sévèrement altérées.

Abstract:

Accelerating orthodontic tooth movement has become a topical issue and the corticotomy seems to be the only effective and safe technique reported in the literature. Simultaneously, aesthetic orthodontic treatment with removable clear aligners has become commonly requested. The aim of this paper is to illustrate the management of facilitated aesthetic orthodontic treatment, a combined approach including piezocision corticotomy and clear aligners for orthodontic treatment. Orthodontic planning for traditional clear aligners should be modified to take advantage of the corticotomy technique in order to facilitate the most difficult orthodontic movements needed to achieve treatment completion, where each aligner will be used for four days rather than 15 days for a total time of four months. A corticotomy with a modified minimally invasive flapless piezocision technique should be performed in both jaws at the same time, before the time window of the orthodontic treatment, where the most difficult orthodontic movements are planned. Treatment planning where difficult orthodontic movements, such as anterior open-bite closure and extraction space closure, are easily managed with clear aligners and are presented as examples of facilitated aesthetic orthodontic treatment application. The combination between aesthetic treatment with clear aligners and modified piezocision corticotomy, if carefully planned, seems to represent a synergy that achieves the current goals of orthodontic treatment. The primary objectives of this combination should be facilitating difficult orthodontic movements and reducing treatment duration.

Abstract:

ABSTRACT Periodontal accelerated osteogenic orthodontics (PAOO) is a procedure applying the clinical science of alveolar corticotomy, particulate bone grafting, and the application of orthodontic forces, for accentuated tooth movement. This is theoretically based on the bone healing pattern known as the regional acceleratory phenomenon (RAP). A series of 12 cases, including 8 females and 4 males, were included in the study. The cases were referred from the Department of Orthodontia to the Department of Periodontology, ADC (R&R), having bimaxillary protrusion with an increased overjet. After initial orthodontic alignment, buccal corticotomy procedure was planned. A full-thickness mucoperiosteal flap was reflected from maxillary canine to canine beyond the root apices. Vertical corticotomy cuts were given in the alveolar bone with piezo blades 2 mm apical to the crestal bone in the inter-radicular space midway between the root prominences and were joined by the horizontal cuts apically. Demineralized freeze-dried bone allograft (DFDBA) was placed in the surgical area. The flaps were sutured and pack was placed. Orthodontic retraction was started 2 weeks after the corticotomy procedure. Using this procedure, the treatment objectives were met in just half to one-third of the reported conventional treatment time and the large overjet was reduced to normal. Pre- and posttreatment clinical parameters were recorded, statistically analyzed, and corroborated with similar orthodontic treatment procedures without the use of the corticotomy technique. The present periodontal (PDL) intervention results in quick and stable results for the correction of bimaxillary protrusion cases. It enhances the esthetics and posttreatment orthodontic stability.

Abstract:

Introduction. With an increasing demand for orthodontic treatment for adult patients, orthodontic professionals are constantly seeking novel strategies and technologies that can accelerate tooth movement in order to shorten the treatment period. For instance, in recent years, the influences of different surgical techniques on orthodontic tooth movement in the ipsilateral side of surgery were intensively investigated. Here, we attempt to examine if corticotomy could also affect the rate of tooth movement in the contralateral side of the surgery by using a rodent model. Materials and Methods. 72 eight-week-old Sprague-Dawley rats were randomly divided into three groups as follows: the Control group (orthodontic treatment devices delivered only, no tooth movement), the orthodontic tooth movement (OTM) group (orthodontic treatment devices delivered and orthodontic treatment performed), and the Corticotomy + OTM group (remote corticotomy performed, orthodontic treatment devices delivered, followed by orthodontic treatment). The surgical procedure was conducted on the right side of the maxilla at the time of appliance placement and a force of 60 g was applied between the maxillary left first molar and maxillary incisors using nickel-titanium springs to stimulate OTM. The OTM distance and speed were tracked at 3, 7, 14, and 28 days post-surgery, followed by histological and immunohistochemical assessments. Results. In comparison with orthodontic treatment only, the contralateral corticotomy significantly accelerated OTM. Furthermore, animals undergoing corticotomy + OTM presented with a greater number of osteoclasts on the compression side, stronger staining of the osteogenic marker on the tension side, and higher expression of an inflammatory marker than the OTM group animals. Conclusion. Our current study demonstrates that remote corticotomy effectively accelerates alveolar bone remodeling and OTM. The study enriches our understanding of the regional acceleratory phenomenon (RAP) and offers an alternative strategy for accelerating OTM to shorten the orthodontic treatment period.

Abstract:

The study aimed to evaluate, clinically and radiographically, the effect of partial corticotomy of the buccal plate distal to the canine on the rate of maxillary canine retraction. A clinical trial with the split-mouth design was conducted among twenty orthodontic patients, recommended for first premolar extraction with an age range from 13 to 21 years, selected from patients seeking orthodontic treatment in private dental clinics in Jeddah, Kingdom of Saudi Arabia. After extraction of the maxillary right and left first premolar, partial corticotomy was performed distal to the canine on the right side. The canine retraction was carried out with a power chain on both sides extended between the canine and the maxillary first molar. The data collected from the current study were tabulated and statistically analyzed using an independent sample t-test with p < 0.05 considered statistically significant. The rate of canine retraction was significantly higher on the corticotomy side than the control side (p < 0.05). Under the limitations of the present study, it can be concluded that the technique of partial corticotomy of the buccal plate distal to the canine is a straightforward surgical procedure enhancing the rate of canine retraction significantly.

Abstract:

Abstract We performed an orthodontic treatment combined with corticotomy and the placement of titanium miniplates in an adult patient who desired a shortened treatment period. The patient had an Angle Class I malocclusion with flaring of the maxillary and mandibular incisors. First, titanium miniplates were placed into the buccal alveolar bone of the maxilla for absolute orthodontic anchorage. Second, an edgewise appliance was applied to the maxillary and mandibular teeth. Then, the maxillary first premolars and mandibular second premolars were extracted. At the same time, a corticotomy was performed on the cortical bone of the lingual and buccal sides in the maxillary anterior as well as the mandibular anterior and posterior regions. Leveling was initiated immediately after the corticotomy. The extraction spaces were closed with conventional orthodontic force (approximately 1 N per side). The edgewise appliance was adjusted once every 2 weeks. The total treatment time was 1 year. Cephalometric superimpositions showed no anchorage loss, and panoramic radiographs showed neither significant reduction in the crest bone height nor marked apical root resorption. A corticotomy-facilitated orthodontic treatment with titanium miniplates might shorten an orthodontic treatment period without any anchorage loss or adverse effects.

Abstract:

The acceleration of orthodontic tooth movement due to alveolar corticotomies has been well documented in the literature. It is defined by a phenomenon of transient osteopenia named “the regional acceleratory phenomenon” by Frost. This biological mechanism has been described in studies on both humans and animals. However, other interesting effects in orthodontics are associated with alveolar corticotomies: higher amplitude of tooth movements, a decrease of the root resorptions and an increase of stability after orthodontic treatment.

Abstract:

ABSTRACT Objectives: To investigate the effects of light and heavy forces with corticotomy on tooth movement rate, alveolar bone response, and root resorption in a rat model. Materials and Methods: The right and left sides of 40 male Wistar rats were randomly assigned using the split-mouth design to two groups: light force with corticotomy (LF) and heavy force with corticotomy (HF). Tooth movement was performed on the maxillary first molars using a nickel-titanium closed-coil spring delivering either 10 g (light force) or 50 g (heavy force). Tooth movement and alveolar bone response were assessed by micro–computed tomography (micro-CT) at day 0 as the baseline and on days 7, 14, 21, and 28. Root resorption was examined by histomorphometric analysis at day 28. Results: Micro-CT analysis showed a significantly greater tooth movement in the HF group at days 7 and 14 but no difference in bone volume fraction at any of the observed periods. Histomorphometric analysis found no significant difference in root resorption between the LF and HF groups at day 28. Conclusions: Heavy force with corticotomy increased tooth movement at days 7 and 14 but did not show any difference in alveolar bone change or root resorption.

Abstract:

L’évolution des thérapeutiques orthodontiques doit faire face à une demande croissante de traitements plus courts pour un même résultat final, en particulier chez les patients adultes. Ces dernières années, l’amélioration des techniques orthodontiques, des techniques chirurgicales et anesthésiques en chirurgie orthognathique ont permis un développement considérable des protocoles orthodontico-chirurgicaux et de la prise en charge orthodontique chez le patient adulte. Les corticotomies alvéolaires font partie de ces nouvelles techniques. Elles permettent une facilitation des déplacements dentaires orthodontiques en modifiant localement le métabolisme osseux et en favorisant une ostéopénie transitoire, facilitatrice du mouvement dentaire. Elles augmentent ainsi l’enveloppe des mouvements dentaires possibles avec les techniques conventionnelles. Bien que la littérature récente apporte une meilleure compréhension des effets biologiques des corticotomies, il n’existe que peu d’informations sur le pouvoir ostéogénique de celles-ci. À travers un cas clinique et une revue de la littérature concernant cette technique et ses principes biologiques, nous décrivons les potentielles perspectives d’ostéogénèse induite par les corticotomies alvéolaires.

Abstract:

The conventional method of ridge expansion uses a mucoperiosteal flap elevation to allow bone corticotomy, which is followed by bone expansion performed with chisels and bone expanders. To facilitate corticotomy and avoid flap elevation, bone expansion can be performed in 2 stages. This case report presents a modified 2-stage bone expansion technique to achieve better implant stabilization and wound closure. This modified approach may be an efficient procedure for minimizing complications.

Abstract:

The purpose of this study was to evaluate the efficacy of alveolar corticotomy on orthodontic tooth movement when retracting upper canines compared with the conventionnal treatment. The sample consisted of 30 patients with a mean age of 21 ± 2 years requiring the therapeutic extraction of the maxillary first premolars, with subsequent retraction of the maxillary canines. The subjects were divided into two groups, one receiving orthodontic treatment assisted corticotomy (experimental group) and the other conventional treatment (control group). The velocity of the retraction of the upper canine was evaluated by measuring the distance between the canine and second premolar on each side of the mouth for both groups at 2 months, and 4 months after canine retraction. Results: the velocity of canine was significantly higher on the experimental group than the control group by two times during the first two months after canine retraction. This rate declined to 1.25 times higher after four months. Conclusion: alveolar corticotomy increased orthodontic tooth movement when retracting upper canines.

Abstract:

ABSTRACT This case report describes the interdisciplinary management of a 58-year-old woman who was missing lower first molars and supraerupted maxillary first molars. The treatment plan included intrusion of the upper first molars and corticotomy-assisted mandibular second molar protraction with the aid of temporary anchorage devices. Miniscrews were effective in intrusion of the maxillary first molars and protraction of the lower second molars. Although good functional outcome was achieved in 41 months, the corticotomy-assisted procedure did not significantly reduce the treatment time.
