Vegetal polymer in repair of defects of the orbital floor: an experimental study in rabbits
(Wiley-Blackwell, 2012-12-01)
Background: An experimental study was done to assess the ability of the vegetal polymer miniplates and screws to repair defects of the orbital floor.Methods: An artificial standard-sized defect was created in the bony floor ...
Effect of Passive Fit Absence in the Prosthesis/Implant/Retaining Screw System: A Two-Dimensional Finite Element Analysis
(Lippincott Williams & Wilkins, 2009-11-01)
The misfit between prostheses and implants is a clinical reality, but the level that can be accepted without causing mechanical or biologic problem is not well defined. This study investigates the effect of different levels ...
Comparação entre parafuso de interferência e transcondilar na reconstrução do LCA
(Sociedade Brasileira de Ortopedia e Traumatologia, 2011-01-01)
OBJETIVO: A fixação femoral na reconstrução do Ligamento Cruzado Anterior (LCA) com enxerto de tendões flexores pode variar muito de acordo com a disposição dos materiais e a experiência do cirurgião. Porém os trabalhos ...
Influence of Implant Connection Type on the Biomechanical Environment of Immediately Placed Implants - CT-Based Nonlinear, Three-Dimensional Finite Element Analysis
(Wiley-Blackwell, 2010-01-01)
Purpose:The purpose of the present study was to evaluate the biomechanical environment of immediately placed implants, before and after osseointegration, by comparing three different implant-abutment connection types.Materials ...
Vertical Bone Augmentation Using a Polytetrafluoroethylene Nonporous Barrier for Osseointegrated Implants Partially Inserted in Tibiae of Rabbits
(Lippincott Williams & Wilkins, 2009-04-01)
Purpose: The aim of this study was to evaluate the possibility of obtaining guided bone regeneration using a poly-tetrafluoroethylene (PTFE) nonporous barrier for 2 endosseous implants, partially inserted in tibiae of ...
Finite Element Modeling for Development and Optimization of a Bone Plate for Mandibular Fracture in Dogs
(Nichepubs, 2010-12-01)
This study aimed to develop a plate to treat fractures of the mandibular body in dogs and to validate the project using finite elements and biomechanical essays. Mandible prototypes were produced with 10 oblique ventrorostral ...
BONE SPREADER TECHNIQUE: A PRELIMINARY 3-YEAR STUDY
(Allen Press Inc, 2009-01-01)
The purpose of this study was to observe the clinical outcome of bone spreading and standardized dilation of horizontally resorbed bone during immediate implant placement using a "screw-type" configuration of expansion and ...
Use of extensible internal device in the femur of young dogs
(Schattauer Gmbh-verlag Medizin Naturwissenschaften, 2008-01-01)
An extensible internal device (EID) was developed to preserve growth plate during the treatment of fracture complications or segmental bone loss from tumour resection in children. Since this type of extensible, trans-physeal, ...
Early Bone Healing and Biomechanical Fixation of Dual Acid-Etched and As-Machined Implants with Healing Chambers: An Experimental Study in Dogs
(Quintessence Publishing Co Inc, 2011-01-01)
Purpose: To evaluate the biomechanical fixation, bone-to-implant contact (BIC), and bone morphology of screw-type root-form implants with healing chambers with as-machined or dual acid-etched (DAE) surfaces in a canine ...
