Two tooth preparation methods to make glass fiber splints for stabilizing loose front teeth:A 5-year clinical observation / 中国组织工程研究

ABSTRACT

BACKGROUND:Studies have found that the glass fiber splint which is embedded into the groove on the lingual surface of the affected tooth plus fluid resin fixation between the gap of mobile teeth can achieve more satisfactory clinical effects on the stabilization of loose front teeth. OBJECTIVE:To observe the clinical effects of glass fiber splints prepared using two tooth preparation methods on splinting loose front teeth and their debonding rate through a 5-year fol ow-up visit. METHODS:Ninety-four chronic periodontal disease patients, who had received periodontal treatment, were enrol ed in this study for their loose front teeth of degree II-III. Al the enrol ed patients were good candidates for periodontal splinting strictly in accordance with the indications for periodontal splinting. According to whether the fluid resin was used to seal the gap between the mobile teeth, the 96 patients were divided into two groupspatients undergoing glass fiber splint+fluid resin between the mobile teeth served as experimental group, and those only undergoing glass fiber splint as control group. Al the patients were fol owed by regular clinical referral or telephone fol ow-up for 5 year, to evaluate the fixed effects. RESULTS AND CONCLUSION:During the 5 years of regular clinical referral or telephone fol ow-up, seven of the 76 cases and 12 of the 18 cases were found in the experimental and control groups, respectively, to have debonding between the abutment and the splint. Compared with the control group, the probing depth and attachment loss of affected teeth were improved significantly (P<0.05), and the percentage of alveolar bone height accounting for the root length increased significantly in the experimental group (P<0.05) after 5 years of fol ow-up. Patients in the experimental group felt comfortable without foreign body sensation. The results confirmed that the glass fiber splinting plus fluid resin fixation between the gap of mobile teeth was a better treatment for loose front teeth during the 5-year fol ow-up.
