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 کاملDimensional stability of polyvinyl siloxane impression material reproducing the sulcular area.
The dimensional stability of a thin intra sulcular impression material reproducing the preparation finish line was evaluated. Impressions were taken of a stainless-steel master model of a simulated abutment with a 'gingival sulcus' using Express regular, Express fast and Aquasil. The putty-wash two-step technique was applied with spacer thicknesses of 0.5, 1 and 1.5 mm. Mid mesiodistal and bucc...
متن کاملdimensional stability of two polyvinyl siloxane impression materials in different time intervals
abstract statement of the problem: dental prosthesis is usually made indirectly; therefore dimensional stability of the impression material is very important. every few years, new impression materials with different manufacturers’ claims regarding their better properties are introduced to the dental markets which require more research to evaluate their true dimensional changes. objectives: the ...
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 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 ...
