The long-term dimensional stability of three non-aqueous elastomeric impression materials, a silicone, a polyether and a polysiloxane, were investigated. The testing apparatus was an A.D.A. specification No. 19 test block and mould. The impressions were measured by the use of a travelling stage reflecting microscope and a Quantimet 720 Image Analyzing computer at time zero and again at 4, 24 and 48 h, and at 1, 2, 3 and 4 weeks. Impressions poured immediately had the greatest accuracy for all the materials. The polysiloxane (0.025 mm) and polyether (0.033 mm) showed very little change in dimension after 4 weeks when compared to the test block. However, the silicone showed significant change at 4 h (0.14 mm) and 0.2 mm after 4 weeks. After 4 weeks the polysiloxane maintained the best surface detail, the polyether was adequate but the silicone lost much of its detail in as little as 24 h. The reasons for these findings are discussed.

“…Custom trays provide uniformity of materials which minimizes the dimensional changes that might distort an impression. Gilmore 12 explained the use of custom tray produced dies that were much more accurate than the stock trays. Glen Johnson 13 and Craig RG 14 in their study stated that the accuracy of impressions in the custom tray was found to be more accurate in the vertical dimension then in the stock tray.…”

“…Craig stated that impression materials have improved to such an extent that accuracy may be controlled more with technique than by material itself [1,[37][38][39]. The polymerisation shrinkage values indicate the low value of polymerization contraction obtained with the medium body materials as compared with light bodied products because of the difference in concentration of inert fillers [35].…”

Introduction: Dimensional accuracy of impression materials is crucial for the production of working casts in Fixed Prosthodontics. The accurate replication of tooth preparations and their arch position requires impression materials that exhibit limited distortion. Methods:This study was conducted to comparatively evaluate the dimensional accuracy of additional silicones by comparing two different techniques and spacer designs, by measuring the linear changes in interpreparation distance. The impressions were made from a stainless steel master die simulating a three unit bridge. A total 80 die stone (type IV, Ultrarock) models were obtained from the impressions made using two different parameters. The two different parameters are Multimix and Monophasic technique and different spacer designs. Result:The interpreparation distance of the abutments in the casts was measured using a travelling microscope. Each sample was measured thrice and the mean value was calculated. The results obtained were statistically analysed and the values fall within the clinically acceptable range.
