The case-control study of affecting factors leading to peri-implantitis

Abstract

Abstract: PURPOSE : The relevant factors leading to peri-implantitis are discussed so as to provide evidence for clinical prevention and control. METHODS : A case-control study was conducted. The cases were divided into 2 groups. Group A consisted of 52 cases with confirmed peri-implantitis after dental implantation and prosthesis in our hospital from January 2010 to June 2013; Group B consisted of 95 cases without peri-implantitis after dental implantation and prosthesis at the same time. Logistic regression analysis was conducted to analyze the patients’ own factors and doctors’ surgical performance which were closely related to peri-implantitis with SPSS16.0 software package. RESULTS : Variables significant in single factor analysis were age, diploma, periodontosis, smoking, diabetes, regular teeth cleaning, special care products after implantation and prosthesis pattern of upper structure (P<0.05). Multifactor retrospective analysis suggested that smoking, diabetes, periodontosis, site of implantation were risk factors leading to peri-implantitis while regular teeth cleaning was a protective factor. CONCLUSIONS : Patients’ own factors are main risk factors for peri-implantitis. Therefore we suggest that operation candidates should be strictly selected; hygiene education for high risk patients should be strengthened; follow up visits after operation are necessary in order to detect and treat peri-implantitis in time if it should occur.
