RESUMO
Anterior open bite (AOB) is the insufficient vertical overlapping between the maxillary and mandibular anteriors when the teeth are in centric occlusion. The purpose of this study was to determine the prevalence of AOB in children and adolescents who visited a private dental hospital. In this study, subjects aged between 16 and 18 years with AOB were included. Data about orthodontic examination of patients were taken from preentered dental records of the hospital. Data of patients with AOB regarding age, gender, and intraoral and extraoral features were collected from the case records of the subjects, and statistical analysis was performed (Chi-square test and nonparametric correlations). The prevalence percentage of open bite in the anteriors was 2.7%, with more prevalence in Class 1 subjects (81.5%). Subjects with AOB had competent lips (81.8%), straight nasolabial angle (86.8%), and shallow palatal vault (49.5%). AOB had no significant relationship with the type of malocclusion, palatal vault, and lip competency, according to the Chi-square test. AOB and the nasolabial angle had a significant association. Both acute and right-angled nasolabial angles were commonly seen in adolescent patients with AOB. In children and adolescents visiting a private dental hospital in Chennai, the prevalence of AOB was found to be 2.7%. A significant association was observed between AOB and nasolabial angle.
RESUMO
A manutenção das dimensões do rebordo alveolar pós-extração dentária torna-se fundamental para se alcançar resultados satisfatórios em reabilitações com implantes osseointegráveis. Atualmente, há uma grande variedade de opções de tratamento de rebordos reabsorvidos, entre elas: enxerto de tecido conjuntivo (ETC), regeneração óssea guiada (ROG), enxertos ósseos em bloco, cirurgia ortognática, distração osteogênica, entre outras. A grande dificuldade do cirurgião-dentista está em eleger a técnica mais adequada. Sendo assim, neste artigo desenvolveu-se um método de eleição do tratamento mais viável baseado na avaliação da resposta biológica básica em indivíduos sem alterações sistêmicas (normo responsivos), executado por profissional com domínio das técnicas propostas. Tal método está representado na forma de tabelas e, através da descrição de casos clínicos, visou-se exemplificar a utilização das mesmas para tratar déficits baseados nos trespasses verticaise horizontais do rebordo em relação à posição da coroa clínica...
he maintenance of alveolar ridge after tooth extraction becomes crucial to achieve satisfactory outcomes for dental implant treatment. Nowadays, there are several options for resorbed alveolar ridges, such as connective tissue grafts (CTGs), guided bone regeneration (GBR), block bone grafts, orthognathic surgery, and distraction osteogenics. One of the greatest issues is to choose among the most appropriate technique. Thus, in this article, a more feasible decision-making process based on the evaluation of basic biological response in subjects without systemic changes was developed by a high-skilled professional on those suggested techniques. Such method is summarized and illustrated through clinical case presentations, aiming to demonstrate the use of this process to treat vertical and horizontal overlap defi ciencies regarding clinical crown position...
