Bond strength of denture teeth to denture bases in CAD/CAM-milled, printed, and conventional fabrication techniques.

Bond strength between denture teeth and denture base depends on the fabrication process. Monolithic systems demonstrated optimal bond strength. Among all other combinations, the conventionally polymerized denture base combined with prefabricated teeth showed the best results. Prefabricated teeth and milled teeth in combination with milled denture bases showed similarly good results. Printed denture bases in combination with prefabricated, milled, and printed teeth showed reduced and variable bond strength. A precise bonding protocol is recommended to ensure optimal bonding of different systems.
