Photoelastic stress analysis in prosthetic implants of different diameters: mini, narrow, standard or wide.
PURPOSE This study investigated the biomechanical behavior of screwed partial fixed prosthesis supported by implants with different diameters (2.5 mm; 3.3 mm and 3.75 mm) by using a photoelastic analysis. MATERIALS AND METHODS Six photoelastic models were fabricated in PL-2 resin as single crowns or splinted 3-unit piece. Models were positioned in a circular polariscope and 100-N axial and ob...
متن کاملStress Distribution in Natural Tooth and Implant Supported Removable Partial Denture with Different Attachment Types: A Photoelastic Analysis
Background and Aim: Different attachment designs have been developed to connect implant to natural teeth in partial dentures; however, adequate studies have not been performed to determine stress distribution patterns in these designs. The present study aimed to assess stress distribution patterns in natural tooth and implant supported removable partial denture with different attachment designs...
متن کاملInfluence of restoration type on stress distribution in bone around implants: a three-dimensional finite element analysis.
The three-dimensional finite element analysis method was used to assess stress in bone around titanium implants using three treatment designs for a partially edentulous mandible, under axial (AX), buccolingual (BL), or mesiodistal (MD) loads. For each of these loads, highest stress was calculated in the model with a cantilever prosthesis supported by two implants (M2). Less stress was found in ...
متن کاملEffect of diameter and length on stress distribution of the alveolar crest around immediate loading implants.
BACKGROUND Many clinical observations have shown that immediate loading is indicated when the stabilization of the bone/implant is optimal and when the estimated loads are not excessively high. Nonetheless, more experimental studies are needed to consider the immediate loading protocol as a safe procedure. Mechanical analysis using the finite element (FE) method analysis has been employed by ma...
متن کاملStress analysis in oral obturator prostheses over parallel and tilted implants: photoelastic imaging.
This study aimed to evaluate the stress distribution through the photoelastic method in implant-retained palatal obturators prostheses. Two photoelastic models with bucco-sinusal communication were fabricated, one model without implants and another with two parallel implants and one tilted in the molar region. A conventional obturator prosthesis and five implant-retained obturators dentures wit...
