Evaluation of somE factors that may affEct thE accuracy of implant transfEr imprEssion
Three abutments were connected to the implants and an electroformed bridge was constructed to fit them. Four groups of impressions were made for the implants using abutments as an impression transfers and the ordinary transfers; both were tightened manually and by 30 N/Cm torque. Impressions were poured into stone using new implant analogues. Another two groups of impressions were made using ab...
متن کاملEffect of impression coping and implant angulation on the accuracy of implant impressions: an in vitro study
PURPOSE The purpose of this study was to compare the accuracy of the implant master cast according to the type (pick-up, transfer) and the length (long, short) of the impression copings. MATERIALS AND METHODS The metal master cast was fabricated with three internal connection type implant analogs (Osstem GS III analog), embedded parallel and with 10° of mesial angulation to the center analog....
متن کاملReusability of Implant Impression Copings-an in Vitro Study to Evaluate the Accuracy of Implant Transfer
INTRODUCTION: Implants are the mainstay of prosthetic dentistry nowadays. The number of accessory implant components essential for prosthetic rehabilitation are many. However De novo purchase of these components becomes an expensive treatment modality. So it becomes essential for the clinician to know about the reusability of these implant components without affecting the purpose served by them...
متن کاملDoes Steam Autoclaving Affect the Accuracy of Implant Impression Systems?
The purpose: The aim of this in-vitro pilot study was to evaluate the effect of steam autoclaving of the implant analog and impression coping on the accuracy of impression procedure. Materials and methods: A master casts model was constructed, with a pair of commercially available fixtures. Ten pairs of impression copings were used to make the impression. Implant analogs were then attached to t...
متن کاملComparative Evaluation of Dimensional Accuracy of Impression Techniques for Parallel Implants and Implants Placed with Angulation: An in vitro Study
Objective: This study aims to measure and compare the accu racy of various implant impression techniques in specimens with parallel implants placed at 90° to the horizontal plane and at 75°. Materials and methods: Polyether medium body (3M ESPE Impregum) was selected as the material of choice. Two metal samples with three lab analogs placed in each were used as the master models. One had impla...
