ABSTRACT
The aim of this systematic literature review was to analyze clinical outcomes of pterygoid implant for the treatment of patients with atrophic posterior maxillae and to provide clinical recommendations for this dental implant technique. An extensive search of electronic databases (PubMed/Medline, Science Direct, Lilacs, Embase, and Cochrane Library) was conducted, for articles published between January 1995 and January 2018, to identify literature presenting clinical outcomes of pterygoid implants in the treatment of patients with atrophic posterior maxillae. The systematic review was performed in accordance with PRISMA/PICO statement guidelines, and the risk of bias was assessed (Australian National Health and Medical Research Council scale). The relative risk of implant failure was analyzed within a 95% confidence interval (95% CI). After screening 331 abstracts from the electronic databases, 36 full-text articles were accessed for eligibility, and a total of 6 studies were included in this systematic review (after applying the inclusion and exclusion criteria). All studies were retrospective in nature and were classified with a poor level of evidence. A total of 634 patients received 1.893 pterygoid implants, with a mean implant survival rate of 94.87%. The mean prevalence of implant failure was 0.056 with a 95% CI of 0.04-0.077. This study demonstrates that pterygoid implants can be successfully used in patients with atrophic posterior maxilla. However, the results should be interpreted with caution, given the presence of uncontrolled confounding factors in the included studies.

Bichectomy is an intra oral surgical procedure, which is the excision of Bichat's fat pad, in order to make the patient's face thinner and bring to him/her greater harmony in the facial contour. The surgery is simple, fast, has a low rate of postoperative complications and can be performed by dental surgeons or plastic surgeons. This article will present a case report of a bichectomy procedure conducted by a dental surgeon on a female patient. The aesthetic results of this procedure can be effectively observed after a period of 4 to 6 months, when the swelling of the subcutaneous tissue is completely resorbed
Bichectomia é um procedimento cirúrgico, intraoral, no qual ocorre a excisão das bolas de Bichat, com o objetivo de afinar o rosto do paciente e conferir maior harmonia do contorno facial. A cirurgia é simples, rápida, e apresenta baixo índice de complicações pós cirúrgicas, podendo ser realizada por cirurgiões dentistas ou cirurgiões plásticos. Neste artigo, será apresentado um relato de caso clínico de um procedimento de bichectomia em uma paciente do sexo feminino, realizado por cirurgião dentista. Os resultados estéticos desse procedimento podem ser efetivamente observados após um período de 4 a 6 meses, quando o edema do tecido subcutâneo é completamente reabsorvido.
