Abstract: Objective: The purpose of this study was to evaluate clinical treatment outcomes of fixed partial den-ture with combination of locking taper implant and natural teeth as abutments, and to analyze relevant fac-tors. Methods: Since January 2013-January 2015, a total of 19 implants were placed in 11patients, 17 (89%) in the maxilla and 2(11%) in the mandible. The implants were connected to 23 abutment teeth, 20 in the maxilla and 3 in the mandible of the prosthetic restorations, 34 were porcelain-fused-to-metal, 10 were all ceramic crown. The observation period ranged from 1 year to 3 years recording the average annu-al marginal bone resorption, soft tissue around the implant, technical complications and patient satisfac-tion, and calculating the implant survival rate. Results: The implant cumulative rate for 3 years was 100%, and the average marginal bone resorption was(0.10±0.02)mm. During the following observation pe-riod, 1 patient with diabetes and periodontitis after postloading in 3 month, occurrencing mild gingival swelling, no significant spontaneous bleeding, no pain. About technical complications, 1 patient appeared the crown fall off, 1 patient appeared the porcelain shipping-off, the remaining patients no obvious abnor-malities. The satisfaction is high. Conclusion: The results from the present study support the findings that treatment that combines natural teeth and locking taper implants in the support of rigid superstruc-tures has excellent follow-up results. Nonetheless, results on this clinical study should be validated with a longer evidence.
