Accuracy of a proposed implant impression technique using abutments and metal framework
PURPOSE This study compared the accuracy of an abutment-framework (A-F) taken with open tray impression technique combining cementon crown abutments, a metal framework and resin cement to closed tray and resin-splinted open tray impression techniques for the 3-implant definitive casts. The effect of angulation on the accuracy of these 3 techniques was also evaluated. MATERIAL AND METHODS Thre...
متن کاملA Metal-Acrylic Bar for Splinting Implant Impression Copings
Precise transfer of three-dimensional position of dental implants from oral cavity to the cast needs special considerations in impression making. It has been suggested to splint the copings by bars or acrylic resin material before making impression. Some problems regarding to polymerization shrinkage of acrylic resin have been reported. In this study, we describe a metalacrylic bar tha...
متن کاملExamination of the Position Accuracy of Implant Abutments Reproduced by Intra-Oral Optical Impression
An impression technique called optical impression using intraoral scanner has attracted attention in digital dentistry. This study aimed to evaluate the accuracy of the optical impression, comparing a virtual model reproduced by an intraoral scanner to a working cast made by conventional silicone impression technique. Two implants were placed on a master model. Working casts made of plaster wer...
متن کاملAccuracy of five implant impression technique: effect of splinting materials and methods
PURPOSE The aim of this study was to evaluate the effect of dimensional stability of splinting material on the accuracy of master casts. MATERIALS AND METHODS A stainless steel metal model with 6 implants embedded was used as a master model. Implant level impressions were made after square impression copings were splinted using 5 different techniques as follows. (1) Splinted with autopolymeri...
متن کاملA systematic review of the performance of ceramic and metal implant abutments supporting fixed implant reconstructions.
OBJECTIVES The objective of this systematic review was to assess the 5-year survival rates and incidences of complications associated with ceramic abutments and to compare them with those of metal abutments. METHODS An electronic Medline search complemented by manual searching was conducted to identify randomized-controlled clinical trials, and prospective and retrospective studies providing ...
