Abstract
Background: Dental implant treatment has been gradually considered as the treatment of choice for patients with tooth loss, due to its very high success rate.
Aim: To evaluate the clinical treatment outcome and complications found in patients who received implant supported and fixed restorations at a Center of Excellence for implantology clinic between January 2012 and December 2013.
Materials and methods: Data from implant treatment records between January 2012 and December 2013 were obtained. The patients were recalled for clinical follow-up after 1 year of loading. The term of the implant success was defined related to the implant is still physically in the mouth. Clinical indices were evaluated followed by criteria of the International Congress of Oral Implantologists (Pisa Consensus).
Results: Ninety eight patients with 156 implants were treated with fixed restorations on implants, 17 patients with 34 implants received implant-retained overdenture treatment. Of 98 patients, 60 patients with 110 implants were able to come for clinical follow-up. The total survival rate of the implants with fixed restoration treatment was 97.27% (3 implants failed). The most frequent complication found in the study was abutment screw loosening (15.45%). Marginal bone resorption was found mostly in a horizontal bone loss pattern; the horizontal loss was less than 1 mm.
Conclusions: This study showed survival rate of implant treatment was 97.27% and comparable to the findings of other studies. Abutment screw loosening was the most common complication (15.45%). Regular recall of patients is strongly suggested to reduce this complication.
