Accuracy of impression techniques for implants. Part 1 - Influence of transfer copings surface abrasion
(2008-12-01)
Purpose: This study evaluated the influence of surface abrasion of transfer copings to obtain a precise master cast for a partially edentulous restoration with different inclinations. Materials and Methods: Replicas (N = ...
Comparison of impression techniques and double pouring by dental cast's accuracy. Preliminary clinical-lab trial
(2019-01-01)
Aim: This study compared impression techniques and double pouring by means of cast's accuracy. Methods: For each patient (n=10), impressions from right maxillary canine to first molar were made with acrylic resin trays and ...
Use of Resin-Based Provisional Material to Create the Posterior Palatal Seal in Complete Denture Definitive Impressions
(2017-01-01)
The purpose of this article was to present an alternative procedure using resin-based provisional material to create the posterior palatal seal (PPS). This method offers more practicality in clinical routine and increased ...
Microdeformation of Infrastructure for Implant-Supported fixed Dental Prosthesis by Strain-Gauge Method: Influence of Technique and Material Impression
(Assoc Apoio Pesquisa & Saude Bucal-apesb, 2015-01-01)
Objective: To verify the structural microdeformation by strain gages, around implants that have metal infrastructure, obtained by different materials and techniques impressions. Material and Methods: Three internal hexagon ...
Evaluation of a two-step pouring technique for implant-supported prostheses impression
(2010-09-07)
The aim of this study was to evaluate the efficacy of a pouring technique for implant-supported prostheses impressions. A metallic matrix (control group) with two implants positioned at 90 and 65 degrees was fabricated. ...
Comparison of the accuracy for three dental impression techniques and index: An in vitro study
(2013-09-27)
Objectives: This in vitro study compared the dimensional accuracy of stone index (I) and three impression techniques: tapered impression copings (T), squared impression copings (S) and modified squared impression copings ...
Evaluation of transfer impressions for osseointegrated implants at various angulations
(2004-12-01)
The accuracy of impressions that transfer the relationship of the implant to the metal framework of the prosthesis continues to be a problem. This study was designed to evaluate the accuracy of the transfer process under ...
An Implant-Transfer Technique Without Impression Material
(Lippincott Williams & Wilkins, 2010-07-01)
Different transfer impression techniques for implant-supported prostheses have been suggested to obtain a working cast. This article describes and illustrates clinical and laboratory pros-thodontic procedures to transfer ...
