Abstract: PURPOSE: To evaluate the effect of fiber reinforcement composites (FRC) in treating chronic periodontitis with dentition defect. METHODS: Thirty patients who had chronic periodontitis and missed less than 2 lower anterior teeth were chosen. After appropriate periodontal treatment, EverStick fibers were used to fabricate splint with the missing teeth repaired. One month, 6 months, 1 year and 2 years after treatment, periodontal indexes such as plaque index (PLI), gingival index (GI) and probe depth (PD) were recorded and the patients’ satisfaction was evaluated. SPSS 17.0 software package was used for statistical analysis. RESULTS: The results showed that no significant difference was found in PLI and GI during observation period (P>0.05). PD decreased significantly after 6 months of observation (P<0.05). Patients’ satisfaction degree for aesthetics, pronunciation, comfort and function was beyond 80%. CONCLUSIONS: Using FRC technique in chronic periodontitis with dentition defect can effectively fix the loosen teeth and maintain physical function. Appropriate periodontal treatment every 6 months is the key factor for satisfactory results.
