Abstract
Purpose: To evaluate and compare the effect of CAD/CAM, thermoplastic, and conventional denture bases on denture retention, bone height, and density in implant-supported mandibular overdentures. Materials and Methods: Eighteen completely edentulous patients were selected, and for each patient, two implants were installed at the canine area of the mandible. After the osseointegration period, abutments were installed over the implants, and the patients were divided into three groups. Group I: Six patients received maxillary and mandibular heat-cured acrylic resin dentures. Group II: Six patients received maxillary heat-cured acrylic resin dentures and mandibular dentures with a thermoplastic denture base. Group III: Six patients received maxillary heat-cured acrylic resin dentures and mandibular denture bases fabricated by CAD-CAM technology. The patients were evaluated clinically and radiographically. Results: Regarding denture retention, the highest value was recorded in group (III) followed by group (II) while the lowest value was recorded in group (I). Regarding radiographic assessment, the amount of bone height loss was found to be higher in a group (I) compared to the other two groups. Bone density showed the lowest change in a group (I) compared to groups (II and III). Conclusion: Thermoplastic and CAD CAM denture bases showed higher results than conventional dentures as regards denture retention and alveolar bone preservation.
