Comparison Between Single Implant Retained Partial Over-denture and Conventional Partial Denture

Overview

In this study we are going to evaluate patient satisfaction as well as the amount of bone loss on using single implant retained partial over-denture versus conventional partial denture for treatment of mandibular Kennedy class IV cases

All the procedures will be made in the outpatient clinic of the removable prosthodontics department, faculty of oral medicine, Cairo University except the CBCT will be performed in the Oral radiology department, faculty of oral medicine, Cairo University. The selected patients will be informed of the nature of the research work and informed consent will be signed by each one of them. Only motivated patients who showed co-operation will participate in the study. Patients will be randomly divided into 2 groups. Clinical examination and investigations will be carried out for the eligible patients including TMJ examination and intraoral examination for oral mucosa. Diagnostic charts will be prepared with full medical and dental history as well as radiographic records. The upper and lower study casts were mounted on a semi-adjustable articulator to evaluate the interarch space and the occlusal plane. Abutment teeth will be evaluated regarding mobility, caries, existing restoration, over eruption, and malalignment. Pocket depth around the abutment teeth will be measured buccally, lingually, and proximally. Radiographic evaluation of all abutment teeth will be carried out to assess the amount of bone support, crestal bone height, continuity of lamina dura, periapical pathosis, crown/root ratio, and root form. Panoramic radiograph also to evaluate the bone quality and quantity in the lower anterior region. All the patients will be motivated for meticulous oral hygiene. In (Group I) The design of the finished partial overdenture will be as follows; two rests on principle abutments and lingual plate major connector. The trial of the metallic framework will be carried out for proper seat and fit. Patients will receive anterior single implant in the mandibular sympheseal region. The locator attachment will be inserted into the implant fixture, leaving the attachment base protruding at least 2 mm above the tissue surface. The partial overdenture will be filled with resin, and the patient will be guided to occlude in centric occlusion. The partial overdenture will be removed after the resin curing and adjusted accordingly to assure a comfortable fit. In (Group2) The design of the finished removable partial denture will be as follows; double Aker clasp on mandibular second premolar and first molar, with no indirect retention and lingual plate as major connector .
