Polymeric Denture Base Materials: A Review.

An ideal denture base must have good physical and mechanical properties, biocompatibility, and esthetic properties. Various polymeric materials have been used to construct denture bases. Polymethyl methacrylate (PMMA) is the most used biomaterial for dentures fabrication due to its favorable properties, which include ease of processing and pigmenting, sufficient mechanical properties, economy, and low toxicity.

MicroCT evaluation for CAD/CAM occlusal veneer fit using two materials and three cement space settings.

This study was aimed to evaluate the fit of occlusal veneer restoration for two CAD/CAM materials with different cement space settings, using microCT scans. Sixty resin dies were made and divided into two groups (n=30) according to the materials, (I): Hybrid all-ceramic, and (II): zirconia-reinforced lithium silicate glass-ceramic. Each group was subdivided into three subgroups (n=10) according to the cement space parameters (30, 40, and 50 µm).

Clinical performance of single implant-supported ceramic and metal-ceramic crowns: A systematic review and meta-analysis of randomized clinical trials.

Statement Of Problem: Evidence relating to the choice of materials for single implant-supported crowns is sparse.

Purpose: The purpose of this systematic review and meta-analysis was to assess articles that compared the clinical performance of ceramic and metal-ceramic (MC) implant-supported single crowns with regard to prosthesis failure, complication rate, and patient satisfaction.

Material And Methods: A comprehensive search of databases (PubMed/MEDLINE, Scopus, and Cochrane Library) was performed.
