| Abstract | ||
| Objectives: The present study was conducted to investigate the retention and the patient satisfaction of the Thermoplastic Acetal resin distal extension partial denture prosthesis with different denture base extension length either extended to covered the retro molar pad or extended just at the anterior border of the retro molar pad in unmodified Kennedy class II mandibular cases. Thermoplastic Acetal resin partial denture is more comfortable and can replace any number of teeth in a dental arch. Methods: Total number of ten healthy patients with unmodified Kennedy class II mandibular cases were selected and received extra coronal attachment on the experimental side , and received unilateral partial denture with thermoplastic Acetal resin framework. The patients were grouped into two groups. Group I received mandibular unilateral distal(without denture base extension) just end at the anterior border of the retro molar padand group II received mandibular unilateral distal(with denture base extension ) covered the retromolar pad. Then the retention evaluation and patient satisfaction was done at insertion of dentures , six months and after 12 month from the insertion. Results: For both groups regarding the retention evaluation, there was insignificant difference between both groups as P-value > 0.05. Regarding the patient satisfaction Group I (without denture base extension) showed statistically significantly higher mean satisfaction score than Group II. Conclusions: The patients were received mandibular unilateral distal(without denture base extension) more satisfied by the prosthesis. and regarding the retention there was non significant difference between both groups so theunilateral partial denture with thermoplastic Acetal resin framework without denture base extension more preferable . | ||
