Abstract:

BACKGROUND: Combination of metal materials and resin is used mostly for stabilization of mobile teeth at present. But the materials are often characterized with instability, complicate to operate, unqualified biocompatibility, and so on.
OBJECTIVE: To analysis of the clinical effect and influencing factors of Biosplint materials on the stabilization of mobile teeth.
METHODS: The clinical data of 80 patients admitted at Jinshan Hospital of Fudan University from January 2008 to December 2010 were retrospectively analyzed. The patients were divided into two groups according to the stabilization materials: the experimental group underwent mobile teeth stabilization by Biosplint materials, while the control group was preformed with mobile teeth stabilization by stainless steel wire joint mobility resin.
RESULTS AND CONCLUSION: All patients were followed-up for 12 months. Forty-four teeth were fixed successfully in the experimental group and the success rate was 91%; 24 teeth were fixed successfully in the control group and the success rate was 69%. There was a significant difference in the success rate between two groups (P < 0.05). The plaque index in the experimental group was lower than that in the control group (P < 0.05). Ages, levels of teeth loosening, times of loosening, absorption of alveolar bones and materials were influencing factors for Biosplint materials in the mobile teeth stabilization. Biosplint materials have a good adhesion with teeth and dental arch, and have the advantages for the maintenance of oral hygiene, structural stability, good-looking and good therapeutic efficacy.
