Shear bond strength of artificial teeth used with CAD/CAM PMMA versus heat cure acrylic resins for complete denture - A systematic review

Abstract

The present systematic review evaluates the shear bond strength of artificial teeth bonded to CAD/CAM PMMA and heat-cure acrylic resins used in complete denture manufacturing. The study aims to determine the superior bonding material, contributing to enhanced denture durability and patient satisfaction. A comprehensive search of databases including PubMed, MEDLINE, DOAJ, Cochrane Library and Scopus was conducted, adhering to PRISMA 2020 guidelines. Studies were assessed for inclusion based on specific criteria, and the data were analyzed using Review Manager (RevMan) 5.3. The findings suggest that while both materials provide adequate bond strength, differences exist that may influence material choice in clinical practice.
