1. Open Reduction and Internal Fixation of Mandibular Fracture without Rigid Maxillomandibular Fixation
Introduction The ability to treat fracture with open reduction and internal fixation (OR/IF) has dramatically revolutionized the approach to mandible fracture. With OR/IF, the postoperative role of rigid maxillomandibular fixation (MMF) has declined, but it is used to maintain proper occlusion until internal fixation of the fracture is achieved. Objective

2. Open reduction and internal fixation of posterior pilon fractures with buttress plate
Objective: Posterior pilon fractures are rare injuries and have not yet gained well recognition. The purpose of this study was to present the treatment outcome for patients with posterior pilon fractures treated with buttress plate. Method: In this retrospective study we identified patients with posterior pilon fractures of the distal tibia who had und

3. Necessidade de reabordagem cirúrgica após tratamento de fraturas mandibulares por fixação interna rígida / Necessity of surgical retreatment in mandibular fractures after treatment by rigid internal fixation
As fraturas de mandíbula são freqüentes e o seu tratamento é por meio de fixação interna rígida. Complicações podem ocorrer após o tratamento das fraturas mandibulares levando a necessidade de reabordagem cirúrgica, havendo poucos estudos a esse respeito na literatura. A proposta deste estudo retrospectivo foi avaliar as características, os poss�

4. Applied mechanics of the Puricelli osteotomy : a linear elastic analysis with the finite element method
Background: Surgical orthopedic treatment of the mandible depends on the development of techniques resulting in adequate healing processes. In a new technical and conceptual alternative recently introduced by Puricelli, osteotomy is performed in a more distal region, next to the mental foramen. The method results in an increased area of bone contact, resulti

5. Analise da estabilidade do reposicionamento inferior da maxila sem a utilização de enxerto interposicional : um estudo cefalometrico retrospectivo / Analysis of stability after maxillary inferior repositioning without interpositional graft : a retrospective cephalometric study
The true vertical maxillary deficiency is a characteristic of Short Face Syndrome (CFS), in these patients, the inferior repositioning of the maxilla is indicated in order to provide a better facial esthetics and improved function. But this surgical movement has been described as the most instable movement, and interpositional autogenous bone graft usually i

6. Estudo biomecanico de tres tecnicas diferentes de fixações metalicas utilizadas em osteotomia sagital do ramo mandibular / Biomechanical evaluation of three different techniques of rigid fixation in sagital split ramus osteotomy
Studies have considered many techniques and methods of rigid internal fixation (RIF) leads to obtain greater stability to the bone segments and minimum displacement of the condyles after performed the sagittal split ramus osteotomy (SSRO). In this way, the purpose of this study was to evaluate by means of mechanical compression testing model with synthetic h

7. Mechanical and photoelastic analysis of two methods of rigid internal fixation in mandfibular advancement / Analise mecanica e fotoelastica das tecnica de fixação interna rigida da osteotomia sagital utilizando placa convencional e placa com sistema de travamento em avanços mandibulares
O propósito neste estudo foi realizar avaliação mecânica e fotoelástica de dois diferentes sistemas de fixação interna rígida (FIR): placas convencionais e placas com sistema de travamento. Para avaliação mecânica foi realizado teste de carregamento linear em réplicas de hemimandíbulas humanas dentadas seccionadas na região de ramo mandibular,

8. Evaluation of the stability of mandibular sagital osteotomy fixation using bicortical screws inserted with 60º and 90º degrees angles. Biomechanical study in sheep mandibles / Avaliação da estabilidade na fixação da osteotomia sagital mandibular utilizando parafusos bicorticais inseridos com angulação de 60° e 90°. Estudo biomecânico em mandíbulas de carneiro
This research was developed to evaluate the mechanical resistance obtained with positional bicortical screws used for internal rigid fixation of bicortical split mandibular ramus osteotomy, comparing two different screw insertion angulations. The traditional technique, most commonly used, for the fixation of bicortical split mandibular ramus osteotomy uses a

9. Comparative biomechanical evaluation of flexion resistance between absorbable and metalic plate and screws used in mandibular body poliuretane / Estudo comparativo da resistencia mecanica a flexão de placas e parafusos reabsorviveis e metalicos utilizados em osteotomias de corpo em mandibulas de poliuretano
The meaning of this study was to evaluate and compare the resistance to flexion between metallic and absorbable plates and screws for rigid internal fixation. It was used synthetic hemimandible of polyurethane, in which one was performed a straight cut between second premolar and first molar, simulating a breaking of mandibular body. It was established two g

12. Self-reinforced polymeric plates and screws for rigid internal fixation of fractures / Placas e parafusos polimericos auto-reforçados para fixação interna rigida de fraturas
O objetivo deste trabalho foi preparar placas e parafusos auto-reforçados a partir do copolímero poli(L/DL ácido láctico), para serem utilizados na fixação interna rígida de fraturas. Este copolímero pode ser hidrolisado quando inserido no corpo humano e seus produtos de degradação são expelidos através do ciclo metabólico. Foi construído um ap
