ABSTRACT
Over the past many years, various bone plating systems have been developed to provide stable fixation for the mandible fractures were proposed and performed. The aim of the study was to evaluate efficacy of three dimensional (3-D)titanium mini plates in the management of mandibular fractures, and to analyze structural stability of the fractured bone fragments after fixation, to evaluate the biocompatibility of the three dimensional plating system and the morbidity of three dimensional plating system. Patients and Methods: 20 patients with mandibular fractures required open reduction internal fixation of the fractures using three dimensional mini plate osteosynthesis over a period of 2 yrs. prospectively. Conclusions: Three dimensional titanium miniplates provide good stabilization of fractured fragments in three dimensions due to closed quadrangular geometric shape and ease of contouring and adapting. Less surgical exposure of underlying fracture site is needed, with a minimal traction of the surrounding soft tissue. They are biocompatible and no morbidity seen in our study.
ABSTRACT
Este trabalho descreve uma nova forma de ancoragem por meio de miniplacas denominada SAO®, Sistema de Apoio Ósseo para Mecânica Ortodôntica. Após a descrição do sistema, protocolos de tratamento para mordidas abertas esqueléticas são apresentados. A aplicação de cantiléveres e alças apoiadas diretamente nos tubos do sistema de ancoragem permite que associações de problemas verticais e sagitais (Classe II e III) sejam tratadas de formas distintas. A aplicação de forças leves e constantes e o controle tridimensional das forças aplicadas são o grande diferencial desse novo sistema.
This paper describes the SAO®, Sistema de Apoio Ósseo para Mecânica Ortodôntica (Skeletal Supported System for Orthodontic Mechanics), a new approach for anchorage by means of mini-plates. After the description of the system, treatment protocols for skeletal openbite cases are presented. The use of cantilevers and different spring configurations attached directly in the tubes of the anchorage system allows various approaches for vertical and sagittal discrepancies.

INTRODUÇÃO: o tratamento das deformidades e más oclusões que incluem mordidas abertas anteriores foi uma das primeiras aplicações de miniplacas como forma de ancoragem ortodôntica. A implementação desse sistema de tratamento reduz o número de pacientes indicados para a cirurgia ortognática e simplifica muitos problemas. Nessa abordagem, os dentes posteriores são intruídos e a mandíbula sofre um giro no sentido anti-horário, diminuindo a altura facial inferior e projetando os pogônios de tecidos duro e mole. OBJETIVO: o presente artigo apresenta os fundamentos da mecânica ortodôntica para correção da mordida aberta anterior e os ilustra com uma série de casos clínicos.
INTRODUCTION: The treatment of facial deformities and malocclusions, such as anterior open bite, was one of the first applications of miniplates for orthodontic anchorage. The use of this treatment system reduces the number of patients referred to orthognathic surgery and simplifies many problems. This approach applies intrusive forces to posterior teeth, and the mandible undergoes counterclockwise rotation, which decreases lower facial height and advances the projection of hard and soft tissue pogonions. OBJECTIVE: This study describes the principles of orthodontic mechanics in the correction of anterior open bite and illustrates these principles with a series of cases.
