AIM The aim of the present study is to compare the various elastomeric impression materials in terms of accuracy and dimensional stability, with respect to obtaining multiple casts from a single elastomeric impression at various times of pours. MATERIALS AND METHODS Three master dies were prepared for the impression making, two of these were made of brass containing a central hole with underc...

To formulate an alginate dental impression material with virucidal properties, experimental alginate dental impression materials were developed and the formulations adjusted in order to study the effect on pH profiles during setting. Commercially available materials served as a comparison. Eight experimental materials were tested for antiviral activity against Herpes Simplex Virus type 1 (HSV-1...

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...

The purpose of this study was to clinically assess the precision of margins reproduction using some impression techniques following application of different retraction materials. A PVS impression material with different viscosities and an injectable tissue retraction material were chosen to make impression using two impression techniques. Traditional retraction cord was used as a control. A num...

Figure 2. Hot melt adhesive-made flexible cast. The use of flexible casts and dies for the chairside fabrication of interim restorations has been reported to overcome the drawbacks of the direct technique and provide a safe and biocompatible fabrication process. Because of the elasticity of these casts, removing the interim restoration after complete setting is easy, and the integrity of the ca...

OBJECTIVES The objective of the following study is to evaluate the interaction between the resin materials used in immediate dentin sealing (IDS) techniques and impression materials with two different techniques to eliminate the oxygen-inhibition layer. MATERIALS AND METHODS The occlusal dentin surface of 35 human molars was exposed. The teeth were used in two Groups: Group 1 - Impression wit...
