ABSTRACT
AbstractSurgically assisted rapid maxillary expansion (SARME) is the treatment of choice to adult patients even with severe transversal maxillary discrepancies. However, the adequate retention period to achieve the bone remodeling, thus assuring treatment stability, is controversial.Objective To evaluate the opening pattern and bone neoformation process at the midpalatal suture in patients submitted to surgically assisted (SARME) through cone beam computed tomography (CBCT).Material and Methods Fourteen patients were submitted to SARME through subtotal Le Fort I osteotomy. Both the opening pattern and the mean bone density at midpalatal suture area to evaluate bone formation were assessed pre- and post-operatively (15, 60 and 180 days) through CBCT.Results Type I opening pattern (from anterior to posterior nasal spine) occurred in 12 subjects while type II opening pattern (from anterior nasal spine to transverse palatine suture) occurred in 2 individuals. The 180-day postoperative mean (PO 180) of bone density value was 49.9% of the preoperative mean (Pre) value.Conclusions The opening pattern of midpalatal suture is more related to patients’ age (23.9 years in type I and 33.5 years in type II) and surgical technique. It was not possible to observe complete bone formation at midpalatal suture area at the ending of the retention period studied (180 days).

Introdução: Os dentes não irrompidos mais comumente encontrados são os terceiros molares inferiores, sendo a sua etiologia debatida dentro da literatura, sendo diversas causas atribuídas a essa situação. Por outro lado, a retenção do segundo molar inferior, não apresenta a mesma freqüência, apresentando-se como uma condição rara, assim como a retenção simultânea de ambos os dentes. Relatos na literatura classificam os casos em que esses dentes se apresentam simultaneamente impactados estando a superfície oclusal dos mesmos conectadas por um mesmo folículo pericoronário e as raízes em direção oposta como Kissing Molars. O tratamento de escolha para esses casos é a remoção cirúrgica de ambos os dentes. Objetivo: O presente trabalho visa expor um caso clínico sobre kissing molars , bem como o seu manejo. Material e método: Este relato de caso descreve dois casos clínicos de Kissing Molars e seus respectivos tratamentos. Resultado e conclusão: No presente trabalho temos a apresentação de um relato de caso clínico de um kissing molars, bem como o seu manejo sem complicações ao paciente.
Introduction: Mandibular third molars are the most common unerupted teeth, whose etiology of this fact is debated on literature, being several factors causing such phenomena. On the other hand the retention of the mandibular second molar, does not present the same frequency, being a rare clinical condition, as well as the simultaneous retention of both teeth. Reports in literature classify the cases in which these teeth are simultaneously impacted with oclusal surfaces contacting each other united by the same follicular space and the roots in the opposite directions like Kissing Molars. The treatment of choice for these cases is the surgical removal of both teeth. Objective: The present work aims to expose a case about kissing molars and its management. Material and method: This case report describes two cases of Kissing Molars and their treatment. Result and conclusion: In this paper we present a case report of a kissing molars and its management to the patient without complications.

A prevenção das complicações cirúrgicas odontológicas na maxila depende de fatores que envolvem a habilidade do cirurgião, o conhecimento da anatomia e fisiologia dos tecidos, planejamento correto, anamnese e exame físico, técnicas radiográficas específicas, qualidade das imagens e da capacidade de interpretá-las. Radiografias intra e extrabucais são fundamentais no planejamento cirúrgico e minimizam as complicações, pois permitem melhor planejamento e, consequentemente, maior sucesso cirúrgico, pois auxiliam na avaliação das estruturas ósseas e dentárias e dos reparos anatômicos na área da intervenção cirúrgica. Nosso estudo relacionou os achados na literatura com o estudo de casos clínicos e radiográficos já documentados no Departamento de Estomatologia, disciplinas de Radiologia e Cirurgia da FOBUS P.
The prevention of dental maxillary surgical complications depends on factors that involve the surgeons skill, knowledge of anatomy and physiology of tissues, proper planning, history and physical examination, radiographic techniques specific quality of the images and the ability to interpret them. Intraand extraoral radiographs are essential in surgical planning and minimize the complications, because they allow better planning and, consequently, greater surgical success, because they help in the evaluation of bone and tooth structures and anatomical landmarks in the area of surgery. Our study findings in the literature related to the study of clinical and radiographic cases already documented in the Department of Stomatology, Department of Radiology and Surgery, FOB-USP.
