| dc.description.abstract | Questions have been raised about whether the elasticity of the impression material, the inter-implant angulation, and the combination of these factors affect the impression accuracy of the implant impression. Given its favorable properties, Polyvinyl Siloxane (PVS) has been recommended as an impression material for clinical use, and thus selected for this study. The objectives of this study were to determine the modulus of elasticity of two PVS (medium body) impression materials, to compare the combined effects of impression material elasticity and dental implant analog angulation (0°, 5°, 10°, and 15°) on the accuracy of the impression, to compare the effect of impression material elasticity on the accuracy of the dental implant analog impression regardless of the inter-implant angulation and to compare the effect of dental implant analog angulation regardless of the material elasticity on the accuracy of the impression. Tensile tests were done to compare the modulus of elasticity between the medium body Aquasil PVS material (‘Aquasil’) and the medium body Virtual PVS material (‘Virtual’). Four block shaped acrylic master models were fabricated with two implant analogs in each: the first was placed at 0° angulation (reference implant) while the second placed at 0°, 5°, 10°, and 15° respectively. Sixty-four impressions were taken, 16 impressions for each of the four master casts, eight of them made using Aquasil impression material and the other eight impressions with Virtual impression material. | en_US |
