Outline of Final Research Achievements

The aim of this study was to analyze the effects of soft tissue condition on the outcome of implant therapy in patients with periodontitis. The subjects were 109 sequential sampling outcome patients with dental implant treatment in which completed periodontal treatment, were responding to maintenance to continue for more than 3 years. As a results of the logistic regression analysis, gender (female)(p=0.002) and keratinized tissue width(p=0.0001) were extracted as factors contributing to peri-implants bone loss > 1.5mm. Thus, these findings suggest that the presence of 1 ~ 2 mm width of keratinized tissue may be appropriate for the long-term stability of dental implants.
