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

PurposeTo compare implant connected and tooth connected implant supported fixed-detachable mandibular partial dentures clinically and radiographically.Materials and methods20 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.ResultsThere was no statistical significance difference between the two groups (P > 0.05).ConclusionsThe tooth-implant supported prosthesis shows predictable treatment option as the totally implant-supported prosthesis concerning implant survival and loss of marginal bone.
