Comparative Study of the Effect of Storage Environment Temperature on the Accuracy of Hygedent and Chromogel Alginate Impression Materials
Background and Aim: Considering the lack of sufficient and even contradictory studies on the effect of temperature-dependent dimensional changes of alginate before pouring, this study aimed to investigate the effect of storage temperature of Hygedent and Chromogel alginate molds on dimensional stability. Materials and Methods: In this in-vitro experimental study, dimensional changes of two t...
متن کاملeffect of contact time between silicone impression materials and stone on dimensional stability of resultant cast
background numerous factors have an effect on the accuracy of an impression and resultant cast, and these include: impression material, impression technique, tray selection, impression disinfection, storage time of impression before pouring, stone type used for fabrication of cast. up to now, there has been little research conducted on the effect of contact time of a cast with an impression, on...
متن کاملInvestigation of the effects of storage time on the dimensional accuracy of impression materials using cone beam computed tomography
PURPOSE The storage conditions of impressions affect the dimensional accuracy of the impression materials. The aim of the study was to assess the effects of storage time on dimensional accuracy of five different impression materials by cone beam computed tomography (CBCT). MATERIALS AND METHODS Polyether (Impregum), hydrocolloid (Hydrogum and Alginoplast), and silicone (Zetaflow and Honigum) ...
متن کاملDimensional Accuracy of Polyvinyl Siloxane Impression Materials Considering Impression Techniques– A Literature Review
Objectives Impression accuracy is the main determinant of the fit, form and function of prosthetic restorations. Polyvinyl siloxane (PVS) is the material of choice in most clinical situations. The purpose of this paper is to provide an up-to-date review of scientific articles which discuss the dimensional accuracy of PVS impression material using various impression techniques, tray types and sp...
متن کاملAccuracy of Multiple Pour Cast from Various Elastomer Impression Methods
The accurate duplicate cast obtained from a single impression reduces the profession clinical time, patient inconvenience, and extra material cost. The stainless steel working cast model assembly consisting of two abutments and one pontic area was fabricated. Two sets of six each custom aluminum trays were fabricated, with five mm spacer and two mm spacer. The impression methods evaluated durin...
