Dimensional Accuracy of Polyvinyl Siloxane Impression Materials Considering Impression Techniques– A Literature Review
Objectives Impression accuracy is the main determinant of the fit, form and function of prosthetic restorations. Polyvinyl siloxane (PVS) is the material of choice in most clinical situations. The purpose of this paper is to provide an up-to-date review of scientific articles which discuss the dimensional accuracy of PVS impression material using various impression techniques, tray types and sp...
متن کاملThe dimensional accuracy of polyvinyl siloxane impression materials using two different impression techniques: An in vitro study
AIM OF THE STUDY To evaluate and compare the linear dimensional changes of the three representative polyvinyl siloxane (PVS) impression materials and to compare the accuracy of single mix with double mix impression technique. METHODOLOGY A study mold was prepared according to revised American Dental Association specification number 19 for nonaqueous elastic dental impression materials. Three ...
متن کاملAccuracy of impressions with different impression materials in angulated implants.
PURPOSE To evaluate the dimensional accuracy of the resultant (duplicative) casts made from two different impression materials (polyvinyl siloxane and polyether) in parallel and angulated implants. MATERIALS AND METHODS Three definitive master casts (control groups) were fabricated in dental stone with three implants, placed at equi-distance. In first group (control), all three implants were ...
متن کاملThree-dimensional accuracy of different impression techniques for dental implants
BACKGROUND Accurate impression making is an essential prerequisite for achieving a passive fit between the implant and the superstructure. The aim of this in vitro study was to compare the three-dimensional accuracy of open-tray and three closed-tray impression techniques. MATERIALS AND METHODS Three acrylic resin mandibular master models with four parallel implants were used: Biohorizons (BI...
