[Evaluation of the fiber-reinforced composite periodontal splint on fixing loose teeth with severe periodontitis].

Purpose: To evaluate the clinical effects of fiber-reinforced composites for splinting loose teeth after periodontal treatment.
Methods: Patients with severe periodontitis (104 teeth) were randomly divided into fiber-reinforced composites group (58 teeth) and wire-ligation fixation group (46 teeth). After periodontal treatment, the loose teeth were fixed by fibre reinforced composites and wire-ligation. After 1 year of clinical observation,probing depth(PD), attachment loss(AL), gingival sulcus bleeding index (SBI)and plaque index(PLI)were measured. The data was analyzed with SPSS13.0 software package.
Results: Six months after fixation, PD and AL became shallower (P<0.05), however, no significant difference was observed in SBI and PLI in the experimental group. In the control group, PD and AL became shallower, SBI and PLI values were higher (P<0.05). SBI and PLI in wire-ligation fixation group were higher than that in fibre reinforced composites group six months after fixation (P<0.05).
Conclusions: High-strength fibers in the periodontal splint is effective for loose tooth fixation in patient with severe periodontitis.
