1. Mechanical influence of thread pitch on orthodontic mini-implant stability
The aim of this study was to evaluate the effect of pitch distance on the primary stability (PS) of orthodontic mini-implants (MIs) in artificial bone. Twenty experimental MIs were allocated to two groups, according to their geometric design: G1(30oX 0.6 mm) and G2(45o X 0.8 mm), and inserted into artificial bone of different densities: D1 (0.32 g/cm3) and D

2. Desenvolvimento de uma bancada de teste para torque de parafusos para implantes
Componentes de próteses e órteses humanas devem ser confortáveis, capazes de realizar as funções esperadas e, mais do que tudo, confiáveis. O foco deste trabalho é no desenvolvimento e aplicação de uma metodologia de análise de parafusos cirúrgicos. Para tanto foi desenvolvido um aparato mecânico, que consiste em um atuador de torque e um sistema

3. Estudo biomecânico da conexão implante/pilar protético em implantes do sistema cone morse / Biomechanical study of the implant/abutment connection in implants with internal tapered connectios
Internal tapered connections were developed to improve biomechanical properties and to reduce mechanical problems found in external and internal hex implants. This work presents the results of two studies that investigated the biomechanical properties of the implant/abutment connection in implants with internal tapered connections. The purpose of the first s

4. Evaluation of insertional torque and axial pull-out strength of mini-implants for orthodontic anchorage / Avaliação do torque de inserção e da força de arrancamento axial de mini-implantes para ancoragem ortodôntica
Introduction: The objectives of this study were to evaluate insertional torque of miniimplants (MI) for orthodontic anchorage, to compare MI axial pull-out strength at 0 (T0), 15 (T15) and 60 (T60) days after insertion, to determine initial and final cortical bone thickness, and to analyze the correlations among these variables. Methods: Sixty 1.6 x 6.0 mm M
