The 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 کاملDimensional 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 کاملDimensional accuracy of three impression materials by one-step and two-step impression techniques: An in vitro study
Introduction: An accurate impression is essential to create a well-fitted dental prosthesis. This study aimed to compare the dimensional accuracy of three elastomeric materials using one-step and two-step impression techniques. Methods: In this study, 20 impressions were fabricated for each Vinyl siloxane ether (Identium), condensation silicone (Speedex), and a...
متن کاملComparative evaluation of dimensional accuracy of different polyvinyl siloxane putty-wash impression techniques-in vitro study.
BACKGROUND Dimensional accuracy when making impressions is crucial to the quality of fixed prosthodontic treatment, and the impression technique is a critical factor affecting this accuracy. The purpose of this in vitro study was to compare the dimensional accuracy of the casts obtained from one step double mix, two step double mix polyvinyl siloxane putty- wash impression techniques using thre...
متن کاملEffect of different impression techniques on the dimensional accuracy of impressions using various elastomeric impression materials: an in vitro study.
UNLABELLED Production of exemplary crowns and fixed partial dentures depends upon the usage of impression material and its technique of usage that accurately reproduces prepared teeth and their relationship to the adjacent oral structure. AIM To evaluate the linear dimensional accuracy of the elastomeric impressions using various impression techniques using different combinations of viscositi...
