Clinical and radiographical comparative evaluation of implant-connected versus tooth-connected implant supported partial dentures

Purpose: To compare implant connected and tooth connected implant supported fixed-detachable mandibular partial dentures clinically and radiographically. Materials and methods: 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 base line (partial denture insertion) and after 3, 6 and 12 months. Data were collected and statistically analyzed using repeated measures way ANOVA test. Results: There was no statistical significance difference between the two groups (P 0.05). Conclusions: The tooth-implant supported prosthesis shows predictable treatment option as the totally implant-supported prosthesis concerning implant survival and loss of marginal bone.
