[Fundamental studies of impression method. Part 4. Reproducibility of edentulous denture ridge by seating speed and holding pressure of impression tray].
In this study, the author attempted to explicate the infuluence of thedifference in the impression methods for the simulation models based on the hypothetical pressure-displaceability and the form of the alveolar ridge on the reproducibility of the measuring models. For this purpose, the reproducibility of the master cast were examined by use of the threedimensional position-reproducing apparat...
متن کاملIn Vitro Effect of Vent Size and Spacer Thickness on Pressure Produced during Maxillary Edentulous Impression Making by Different Impression Materials
Background and Aim: Inappropriate transfer of pressure during final impression making in fabrication of complete denture can result in ridge resorption. This study aimed to assess the effect of vent size and spacer thickness on pressure produced during maxillary edentulous impression making by different impression materials in vitro. Materials and Methods: This experimental study was carried...
متن کاملInfluences of differences in tray design and impression material on impression pressure at edentulous mandible.
The aim of this study was to examine the effects of tray design and impression material on impression pressure in a clinical simulation model of an edentulous mandible. Two types of polyvinylsiloxane elastomer, one type of polyether elastomer, and one type of alginate were used. The three tray types had no relief, 0.36 mm of relief, or 1.4 mm of relief, with or without escape holes. Impression ...
متن کاملEC DENTAL SCIENCE Case Report An Alternative Implant Impression Technique with Limited Interocclusal Space: Closed-Tray Impression Posts for Open-Tray Impression Technique
Accurate impression is a main requirement for obtaining passive fit of restorations. The aim of this case report is an alternative technique in using closed-tray impression posts for open-tray impression technique for exemplification at a patient that can have limited interocclusal vertical space. After osseointegration, 7 implants examined in edentulous maxilla, open-tray impression technique ...
متن کامل[Dimensional accuracy of thermoplastic impression material Adaptol. Part 1. Influence of handling temperature of impression material].
A thermoplastic impression material Adaptol (J.F. Jelenko & Co.) is used for the impression of denture and has attained good results. But the accuracy of the impression material is not distinct. The purpose of this study was to investigate the influence of handling temperature on dimensional accuracy of the impression material. Part 1. Impressions were made with Adaptol and custom trays. Accura...
