A common challenge encountered with both traditional and digitally produced dentures involves the extraction of artificial teeth from denture base. This narrative review seeks to present an updated perspective on adherence synthetic for base materials, employing diverse methods. Dental technicians often employ chemical approaches mechanical techniques (including abrasion, laser treatment, abrasive blasting) augment retention teeth. However, efficacy these treatments remains uncertain. In certain instances, specific combinations Denture Base Resin (DBR) materials exhibit improved performance in conventional heat-cured following treatments. The primary reasons failure are attributed material incompatibility inadequate copolymerization. As new fabrication continue emerge, further research is imperative identify optimal tooth-DBR combinations. Notably, 3D-printed tooth–DBR have demonstrated reduced bond strength less favorable patterns, while utilizing milled appears be a more prudent choice until advancements additive manufacturing enhance reliability 3D-printing
