Evaluation of Survival Rate and Tissue Health Indexes around the Dio® SM Dental Implants Placed in the Patients of a Dental Office in Isfahan from 2005 until 2010

Dental implants are the choice of treatment for missing teeth. Despite the very good results, implant treatment is also associated with some failures and complications. The aim of this study was evaluation of survival rate and tissue health indexes around the Dio® SM dental implants placed in patients of dental school and a private office in Isfahan from 2005 until 2010.
In this cross sectional study, 94 Dio® SM dental implants in 72 patients via convenience sampling were selected. After that demographic information and Gingival index, Gingival Bleeding index around Dio SM implants, plaque index, pocket depth, Bone loss were fulfilled for patients. Data analyzed using t-test, Chi-square test, Wilcoxon and Pearson test with SPSS Ver. 20 statistical software, at α =0.05.
Among 94 implants, 55.6 % in maxilla, 44.4% in the mandible, 53.19% single and 46.81% were multi-unit. Survival rate of total implants was 80.6% and 19.4% were failed because of different causes. Among indices Gingival index(p=0/001), plaque index(p=0/020),pocket dept (p The results of this study showed that survival rate of Dio® SM implants is lower than acceptable rate but needs to more studies.
