Performance of dental impression materials: Benchmarking of materials and techniques by three-dimensional analysis.
Among other factors, the precision of dental impressions is an important and determining factor for the fit of dental restorations. The aim of this study was to examine the three-dimensional (3D) precision of gypsum dies made using a range of impression techniques and materials. Ten impressions of a steel canine were fabricated for each of the 24 material-method-combinations and poured with typ...
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 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 کاملComparative Analysis of Dimensional Accuracy of Two Types of Silicone Impression Materials: Optosil and Elite-HD
Statement of the Problem: Understanding about impression materials, their properties, uses and manipulation can guide operators towards having more successful restorations. Purpose: The aim of this in vitro study was to compare the accuracy of a condensation silicone impression material, Optosil, and an addition poly siloxane impression material, Elite-HD. Materials and Method: A laboratory mod...
متن کاملEffect of Three Disinfectants on Dimensional Changes of Different Impression Materials
Background and Aim: Disinfection of dental impression materials can alter their dimensional stability, which in turn can affect the accuracy of dental casts. This study aimed to determine the effect of three disinfectants on the dimensional changes of ir-reversible hydrocolloid impression materials and addition silicones. Materials and Methods: Forty alginate and 40 addition silicone impressio...
