The article describes a simple, quick and corrective technique for making the preliminary impression. It records the extensions better as compared to the impressions made using only impression compound. This technique is accurate and gives properly extended custom tray. Any deficiencies seen in the compound primary impression are corrected using this technique hence, this technique is called as...

background: different factors such as impression techniques and materials can affect the passive fi t between the superstructure and implant. the aim of this study was to determine the effect of different impression materials and techniques on the dimensional accuracy of implant defi nitive casts. materials and methods: four internal hex implants (biohorizons ø4 mm) were placed on a metal maxil...

abstract introduction: impression making is one of the most important steps in fixed prosthodontics. due to contra-dictory opinions on the issue of the accuracy of silicone impression material as a function of technique, this study was carried out to assess the dimensional accuracy of master casts made by rapid silicone material as a function of three impression techniques: with 2mm space, with...

This study was carried out to measure the dimensional changes in silicone impression material, which can affect the fitness of the prosthesis. Using both single and double mix techniques, 20 impression samples for each of 3 different proprietary silicones, Xantopren-H, President and Fulldent, were made. Selected measurements were made on the stone casts made from each impression. In all 3 cases...
