Factors affecting bonding strength of artificial teeth to acrylic resin denture bases: A review
Abstract
Introduction: The most common repair in removable prostheses and especially after delivering them to patients is substitution of debonded teeth in their places. Several studies have already been planned to study the factors affecting the bonding strength of artificial teeth to their denture acrylic base resin. The aim of this study was to make a review on the factors which affect bonding strength of artificial teeth to the acrylic denture base resin.Methods and Materials: A thorough literature review was made on the web using Pubmed and Science Direct services. The key words applied for the search were acrylic, dentures, tooth, artificial, denture bases, bonding strength. Since 1952, a total of 54 relevant papers were selected. Conclusion: There is a wide variety in methodology of testing the samples for bond strength. Contamination with wax appears to be the major cause of bond failure between teeth and denture base resins. Also contamination with tin foil substitute seems to reduce bond strength. Application of monomer or adhesive bonding agents and chemicals to acrylic teeth can enhance bond strength values. Heat activated resins produced a higher bond strength than other types of acrylic resins. Key words: Acrylic resins, Dentures, Tooth, Artificial, Denture bases, Bonding strength.
