Abstract

Silanes are extensively used in dental composites to facilitate chemical bonding among the phases of composites. Despite their popularity, the dental application of silanes as coupling agents is still restricted by a few limitations, which include their hydrolytic instability in aqueous oral environment and their inefficiency to bond with nonsilica fillers. Titanate coupling agents can provide good interphase bonding, improve mechanical properties, enhance filler homogenous dispersibility, and modify the rheological behavior of composites. Moreover, moisture resistance can be improved by adding a small amount of titanates. This review aims to evaluate the efficiency of using titanate coupling agents in dental polymer composites and denture bases, particularly when titanium-based fillers are impregnated.
