Statement Of Problem:
Bond failures continue to occur between resin denture teeth and the denture base.
Purpose:
This qualitative study examined a denture tooth modification to determine whether the joint produced between the denture tooth and the denture base resin was stronger than the materials from which it was composed.
Material And Methods:
Modified and unmodified resin denture teeth were processed to a denture base and stressed until fracture occurred. The fragments were saved, labeled, examined, and evaluated.
Results:
The unmodified resin denture teeth, which were displaced from the denture, exhibited no evidence of a bond to the denture base. The modified resin denture teeth fractured before separation could occur.
Conclusion:
Within the limitations of this study, the cingulum ledge lock modification produced a mechanical union of the resin denture teeth tested to the denture base material tested that was stronger than the materials from which the lock was composed.
