Effect of unilateral misfit on preload of retention screws of implant-supported prostheses submitted to mechanical cycling
(2011-01-01)
Purpose: The aim of this study was to evaluate the effect of different levels of unilateral angular misfit on preload maintenance of retention screws of single implant-supported prostheses submitted to mechanical cycling. ...
Regular and switching platform: Bone stress analysis with varying implant diameter
(2013-06-01)
The aim of this study was to evaluate stress distribution of the peri-implant bone by simulating the biomechanical influence of implants with different diameters of regular or platform switched connections by means of ...
Evaluation of the RB-RB/LB-LB mnemonic rule for recording optimally projected intraoral images of dental implants: an in vitro study
(British Inst Radiology, 2012-05-01)
Objective: The aim of this study was to evaluate a simple mnemonic rule (the RB-RB/LB-LB rule) for recording intra-oral radiographs with optimal projection for the control of dental implants.Methods: 30 third-year dental ...
Influence of the implant diameter with different sizes of hexagon: Analysis by 3-dimensional finite element method
(2013-08-01)
The aim of this study was to evaluate the stress distribution in implants of regular platforms and of wide diameter with different sizes of hexagon by the 3-dimensional finite element method. We used simulated 3-dimensional ...
A study of different calcification areas in newly formed bone 8 weeks after insertion of dental implants in rabbit tibias
(1998-10-01)
In orofacial implantology there are many types of implants for the different systems. Among these is the implant surface type, e.g., a screw type, cylindrical and laminar. Furthermore, the implants are different in their ...
Experimental peri-implant tissue breakdown around different dental implant surfaces: Clinical and radiographic evaluation in dogs
(2004-11-01)
Purpose: Tissue reactions to 4 different implant surfaces were evaluated in regard to the development and progression of ligature-induced peri-implantitis. Materials and Methods: In 6 male mongrel dogs, a total of 36 dental ...
A survey of radiographic prescription in dental implant assessment
(British Inst Radiology, 2003-11-01)
Objectives: To survey the current radiographic prescriptions in dental implant assessment amongst dentists in Brazil.Methods: Sixty-nine dentists were interviewed during a dental implant meeting by two calibrated graduate ...
Photoelastic Analysis of Implant-Retained and Conventional Obturator Prostheses With Different Attachment Systems and Soft Relining
(Lippincott Williams & Wilkins, 2011-05-01)
Complete and partial loss of maxillary bone may jeopardize oral physiology and generate complications as oral-sinus-nasal communication. Palatal obturator prostheses are a treatment alternative for rehabilitation of these ...
