Review of dental impression materials.
Major advances in impression materials and their application have occurred during the last decade, with greater emphasis being placed on rubber impression materials than on dental compound, zinc oxide-eugenol, and agar and alginate. Of particular interest has been the effect of disinfection solutions on the qualities of impressions and the biocompatibility of impression materials. The principal...
متن کاملDimensional Changes of Alginate Dental Impression Materials-An Invitro Study.
BACKGROUND Dentists are always looking ahead for more dimensionally stable material for accurate and successful fabrication of prosthesis in this competitive world. Arrival of newer materials and increased material market puts dentists in dilemma for selection of material. AIM The study evaluated the effect of variations in time of pour and temperature on dimensional stability of three brands...
متن کاملDimensional accuracy of 3 silicone dental impression materials.
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...
متن کاملThe Dimensional Stability of Elastomeric Dental Impression Materials
High accuracy dental impression is usually a first step during fabrication of indirect restorations that have to be seated in or on prepared teeth. The dimensional stability of the impression material could have an influence on the accuracy of the final restoration. Elastomeric materials (additioncured silicones and condensationcured silicones) are most frequently used as the impression materia...
متن کاملPerformance of dental impression materials: Benchmarking of materials and techniques by three-dimensional analysis.
Among other factors, the precision of dental impressions is an important and determining factor for the fit of dental restorations. The aim of this study was to examine the three-dimensional (3D) precision of gypsum dies made using a range of impression techniques and materials. Ten impressions of a steel canine were fabricated for each of the 24 material-method-combinations and poured with typ...
