The seismic assessment of existing bridges is the utmost importance to characterise main structural deficiencies, estimate risk, prioritise retrofit interventions, or losses and repair costs in case earthquakes. above tasks require information on damage mechanisms likely occur as well extent over structure. Such types are generally not provided by classical fragility analysis, which mainly focu...

This study evaluated the tension force of cast frameworks made by the technique of framework cemented on prepared abutments using two different resin cements. Forty multi-unit abutment analogs were individually fixed with chemically cured acrylic resin inside PVC cylinders using a parallelometer. Brass cylindrical abutments were tightened to the multi-unit abutments to be used as spacers and th...

STATEMENT OF PROBLEM The clinical outcomes of anterior implant abutments are not well reported. Purpose of the Study To systematically review the existing literature to identify survival, mechanical, biological, and esthetic outcomes of anterior implant abutments. MATERIAL AND METHODS An electronic search was performed using PubMed/MEDLINE with specific search terms and predetermined criteria...

AIM The purpose of this in vitro study was to assess and compare the retention of zirconia copings luted with different luting agents onto zirconia and titanium abutments. MATERIALS AND METHODS Titanium and zirconia abutments were torqued at 35 N/cm onto implant analogs. The samples were divided into two groups: Group A consisted of four titanium abutments and 32 zirconia copings and Group B ...

Abstract Elderly people suffer from more and teeth problems. The tooth-implant-supported prosthesis provides a reliable solution to missing patients. proper dental design prevent overstress is essential due the mechanical characteristics of bridge abutments are different. finite element method widely applied, but experimental validation required. curing shrinkage epoxy applied for photoelastici...

the use of multiple implants in the same jaw requires a detailed knowledge of abutment angulation. the position and angulation of the abutments play an important role in treatment planning and fabrication of the custom tray. therefore diagnostic casts that contain cover screws may cause problems during implant therapy. the current article describes a technique for making a preliminary cast with...

INTRODUCTION The study evaluated a null-hypothesis of no differences of fit between stock abutments and CAD/CAM titanium, gold sputtered and zirconia abutments when examined for radiographic adaptation and Scanning Electron Microcopy (SEM) at their inner aspect. The agreement between microscopic and radiographic fit was also assessed. METHODS Implants (Osseospeed, Astra Tech, Mölndal, Sweden)...

PURPOSE To assess the 5-year survival rate and number of technical, biologic, and esthetic complications involving implant abutments. MATERIALS AND METHODS Electronic (Medline) and hand searches were performed to assess studies on metal and ceramic implant abutments. Relevant data from a previous review were included. Two reviewers independently extracted the data. Failure and complication ra...
