Abstract

Background: Oral rehabilitation with dental implants after a tooth loss has become the most common and predictable treatment plan. The guided surgery with static guides is a more precise surgery than the free-hand method and consequently, the guided surgery should offer a better prosthetic results and less biological complications. Objective: The aim of this study is to compare which of the two following methods of guided surgery with CAD/CAM template or with free hand surgery has less complication rate. Material & Methods: A cross.-sectional study will be performed making a review of the clinical files in CUO (Clinica Universitaria de Odontologia). Different technical aspects of the surgery and all the complications were recorded. Results: From the clinical files of the CUO, 99 patients were selected, 11 of these patients underwent guided surgery and 88 were free-hand surgery. 103 prothesis were hybrid, 25 was overdenture and 22 metal-ceramic full-arch. About the complications, 171 teeth were replaced in resin prosthesis, 24 prosthesis had ceramic chipping, 44 prosthesis had acrylic fracture and 43 had screw loosening. 50 implants were lost in 30 patients. Conclusion: The most common complication was tooth deattachment reaching almost the half of the overall complications. The results of this study are prelimary results, more research is needed to increase the sample size and obtain results with clinical relevance.
