Abstract

Introduction: Complete denture retention is significant to achieve patient comfort while wearing complete denture. Denture retention plays an important role for the patient in feeling secure at the very beginning of denture wearing where neural and muscular controls are not developed yet. Moreover, it is hard to attain stability for the complete denture without establishing adequate retention. Aim: To evaluate the retention of heat cured and thermoplastic acrylic resins in maxillary complete denture bases made with different posterior palatal sealing techniques. Material and methods: Ten completely edentulous patients were selected for the study. Their age ranged from forty to fifty-eight. Four casts were made including a cast with Iowa wax posterior palatal seal, a cast with conventional posterior palatal seal, a cast with beading posterior palatal seal, and a cast with arbitrary posterior palatal seal. Then, the casts were duplicated for fabrication of injection molding acrylic denture bases. Results: The functional posterior palatal seal showed the highest retention. The deference in retention between the heat cure and the thermoplastic acrylic denture bases was not significant. Conclusion: The functional posterior palatal seal gave the upper complete denture the highest retention. The retention of the heat cure and injection molding denture bases was nearly the same.
