dc.description.abstractengThis retrospective study evaluates the clinical outcomes of prefabricated one-piece zirconia abutments and all ceramic crowns in the anterior region over an observation period of five to seven years with closer examination to biological and technical complications. In addition, possible influences of smoking and systematic recall on the survival, success, and chipping were examined. 27 patients (18 women, 9 men) with the range of age of 30 to 82 years with 42 restorations were selected for this study. 41 restorations with a mean observation period of 78.08 months were examined; one abutment was not examined because it was fractured. The sample included 22 non-smoking patients (32 restorations) and 5 smokers (10 restorations). 13 patients with a total of 22 restorations participated on a regular recall, 13 patients (19 restorations) were checked in irregular intervals. For the 41 restorations investigated a complete documentation including radiographs was available at the time of the final examination day. The clinical examination was performed by one independent clinical examiner using a CRF’s sheet, a mirror, and an implant probe. Statistical analysis was performed with the Department of Medical Statistics, University of Göttingen, Germany. The survival rate after 5 and 7 years was 97.62%. The 5-years success rate was 78.16%, the 7-years success rate 74.05%. Regarding the success without chipping, the success rate was 90.30% for both 5 and 7 years. The results indicate that the following events occurred: five chippings, four losses of retention, two abutment screws loosened, and one abutment factured. The sum of events leads to a prevalence of 28.57% of technical complications. The prevalence of biological complications represented by the mucositis (19 patients) and the periimplantitis (2 patients) was 73.08% and 7.69% respectively. Based on the results of the present study zirconia abutments and supported all ceramic crowns can be certified a very high survival und a high success rate for the anterior region. Smoking is a risk factor that lowers the success rate. Systematic recalls have no significant effect on the survival and the success rate.de
