Three kinds of periodontal stabilization splints in severe periodontitis of the mandibular anterior teeth：which one is preferred? / 中国组织工程研究

ABSTRACT

BACKGROUND:It is believed that the splintage can promote periodontal tissue repair and improve the prognosis of loose teeth. However, the force of the splint is associated with the rigidity of the splint and adaptation between the teeth and the splint. OBJECTIVE: To evaluate the therapeutic effects of the nylon composite resin periodontal splint, the fiber-reinforced composite periodontal splint and the bracket periodontal splint on the treatment of severe periodontitis of the mandibular anterior teeth. METHODS:Seventy-two patients with severe periodontitis of the mandibular anterior teeth were randomized into 3 groups, with 24 cases in each group nylon composite resin periodontal splint, fiber-reinforced composite periodontal splint and bracket periodontal splint groups. The clinical effects of the three kinds of periodontal splints and periodontal indexes were compared at 1, 6 and 12 months after splinting. RESULTS AND CONCLUSION: The clinical effects in the group of the fiber-reinforced composite periodontal splint were significantly better than those in the other two groups at 1, 6, 12 months, which were 100%, 100% and 95.8%, respectively. The plaque index, bleeding index, and pocket depth were worse in the group of the nylon composite resin periodontal splint than the other two groups (P < 0.05). Results suggest that the fiber-reinforced composite periodontal splint is preferred to preserve the loosened teeth with severe periodontitis.
