Abstract
Combining natural teeth and implants to support fixed partial dentures has been advocated by certain investigators of implant dentistry and controversies exist because of the different mobilities of teeth and implants; so there is a differential deflection between the visco-elastic intrusion of a natural tooth in its periodontal ligament and the almost negligible elastic deformation of an osseointegrated implant. This difference may induce a fulcrum-like effect and possibly overstress the implant or surrounding bone The purpose of this study was to compare implant connected and tooth connected implant supported fixed-detachable mandibular partial dentures clinically and radiographically. 20 partially edentulous patients with age range (25-50) years old of mandibular class II Kennedy classification were equally divided into two groups receiving a three unit fixed detachable screw retained partial denture, Group (I): Patients with unilateral missing mandibular molars and premolars. Two implants were placed at the mandibular first premolar and first molar areas. Group (II): Patients were selected with missing mandibular molars and second premolar, having the mandibular first premolar in a good periodontal health and good bone support. An implant was placed at the mandibular first molar area and preparation of the first premolar was done and a coping was cemented to the tooth with permanent cement. Each case was evaluated clinically and radiographically at baseline (partial denture insertion) and after 3, 6 and 12 months. Data were collected and statistically analyzed using 2-way ANOVA test with repeated measures. There was no statistical significance difference between the two groups (P0.05).
