Abstract:

BACKGROUND: Splint-like porcelain-fused-metal bridge for periodontal bone defects accompanied by dentition defects induced by periodontitis can increase the bone mineral density rather than bone height around the tooth root. Therefore, there are some limitations for pure splint treatment in the repair of periodontitis-induced periodontal bone defects accompanied by dentition defects.

OBJECTIVE: To compare the restoration method of bone graft in combination with splint-like porcelain-fused-metal bridge treatment and splint-like porcelain-fused-metal bridge alone on curing periodontal disease patients with periodontal bone defects, and to analyze the periodontal conditions.

METHODS: Twenty patients with periodontitis accompanied by Kennedy III dentition defects, who had alveolar bone absorption and were scheduled for porcelain crown treatment, were randomly divided into bone graft group and non-bone graft group, 10 patients in each group. In the bone graft group, bone graft plus splint-like porcelain-fused-metal bridge was performed; only splint-like porcelain-fused-metal bridge was in the non-bonegraft group. Gingival crevicular fluid samples from the groups were collected at 0, 3, 6 months after treatment for measurement of interleukin-1β level. Probing depth and clinical attachment loss were also reexamined and recorded.

RESULTS AND CONCLUSION: Interleukin-1β level decreased gradually in the two groups (P < 0.05), which was decreased more significantly in the bone graft group as compared with the non-bone graft (P < 0.05). As time went by, the probing depth and clinical attachment loss were also decreased in the two groups, which were more significant in the bone graft group (P < 0.05). In addition, there were significant differences in the probing depth and clinical attachment loss of the bone graft group at different time (P < 0.05). These findings indicate that the combination of periodontal bone graft and splint-like porcelain-fused-metal bridge is more effective and beneficial to periodontal tissue reconstruction with periodontal bone defects than the simple splint-like porcelain-fused-metal bridge.
