Book Description
Production of exemplary crowns and fixed partial dentures depends upon the usage of impression materials that accurately reproduces prepared teeth and their relationship to adjacent oral structures. A leading dental manufacturer has introduced an improved elastomeric impression material, but the accuracy of the new material after repeat pours have not been verified.The present study was done to comparatively evaluate dimensional accuracy of vinyl polyether silicone and vinyl polysiloxane elastomeric impression materials after repeated pours at different time intervals.It Was concluded that, because of excellent dimensional stability, both impression materials can be repeatedly poured for two weeks as there is no significant dimensional change overall.

Book Description
Several factors play a role in stability of impressions made from elastomeric impression materials. These include; polymerization shrinkage, loss of by-products during condensation, thermal contraction from oral temperature to room temperature, imbibition when exposed to water, disinfectant or high humidity and incomplete recovery from deformation due to viscoelastic behavior. An ideal impression material should be dimensionally stable over time to allow for pour at the convenience of the operator. Several studies evaluated the dimensional accuracy of elastomeric impression materials based on various factors including effects of repeat pour, temperature, humidity, disinfectants, impression techniques, and filler loading amongst others. Most of the previous studies did not use the standardized method described by the ADA specification for elastomeric impression materials ...

Book Description
The contents of this book touch on the all major dental biomaterials: polymers, composites, ceramics and metals. The first part introduces the readers to the surface physicochemical and mechanical characterizations at the nanoscopic level, and the use of finite element analysis. The second part discusses dental adhesion, resin-based composites, polymerization contraction stress, impression materials and soft liners for total prosthesis. The third part deals with ceramics in restorative dentistry: zirconia and lithium disilicate, the fractography of dental ceramics, as well as bioglass for bone growth. The fourth part discusses the toxicity of mercury in dentistry, and the use of preventive materials for dental diseases. The concluding part identifies imminent techniques for dental biomaterials, such as additive manufacturing (3D printing), and bioprinting in dentistry.
