Panoramic radiographs are important for the evaluation and classification of the third molars position, allowing the diagnosis and planning of extraction. The objective of this study is to evaluate upper and lower third molars positions in panoramic radiographs with the classification methods proposed by Pell and Gregory (1933) and Winter (1926) and the subsequent comparison of results with other authors. Panoramic radiographs of 310 patients were analyzed, 197 female and 113 male, totaling 1,211 third molars. In relation to the upper third molars, the most prevalent positions were: angle compared to the long axis of the second molar of Distoangular form (53.23 %) and the depth of impaction as Class C (48.25 %). In the lower third molars, the most prevalent positions were: angle to the long axis of the second molar in Mesioangular classification (52.96 %), the depth of impaction was B (46.54 %) and the tooth relationship with the mandibular ramus was identified as class I (55.26 %). These results provide information that can be utilized in predicting third molar development in terms of impaction or eruption, assisting dental surgeons in making decisions regarding surgical planning and treatment.
Introdução: a anquilose da articulação temporomandibular (ATM) é caracterizada pela fusão intracapsular do complexo disco-côndilo
IntroduçãoA anquilose da articulação temporomandibular (ATM) é um grande problema dentro da cirurgia oral e maxilofacial, sendo o seu tratamento um grande desafio. Dependendo da idade de incidência e do tempo de anquilose, os pacientes apresentam vários sinais clínicos, incluindo: incapacidade de abrir a boca, assimetria facial, micrognatia mandibular e eixo transverso do plano oclusal alterado 1,2 . O diagnóstico pode ser complementado por radiografias extraorais (panorâmica, submentovertex e incidência de Waters). A tomografia computadorizada promove uma imagem de qualidade melhor, particularmente quando reconstruções multiplanas sagitais estão disponíveis.
PRIMO, B. T.; MACARINI, J. R.; RIVALDO, E. G. & HERNÁNDEZ, P. A. G. Surgical treatment of condylar hyperplasia associated with dentofacial deformity: low condylectomy, articular disc repositioning, and orthognathic surgery. Int. J. Odontostomat., 10(2):207-213, 2016.ABSTRACT: Due to the complexity of the treatment of condylar hyperplasia associated with dentofacial deformities and its complications, if left untreated, the surgeon should be alert to these factors at the time of surgical planning to tailor the optimal therapy for an individual patient. This case report describes a patient with right condylar hyperplasia associated with dentofacial deformity who was treated surgically with low condylectomy, articular disc repositioning and anchoring, and orthognathic surgery, concomitantly, with stable results, satisfactory occlusion and facial harmony.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
