摘 要:目的 探讨烤瓷冠边缘的处理对牙龈健康的影响。方法 收集已做过烤瓷冠桥修复的患者 1 2 9例 ,观察分析修复体边缘的密合性、伸展度及光洁度对被修复牙牙龈健康 (牙龈出血指数 )的影响。结果 ①修复体边缘超过龈下 1mm(Ⅰ_3组 )对牙龈健康的影响最大 ,而其他各组相对较轻。②修复体边缘密合性对牙龈健康状况的影响为 :A组优于B组 ,B组优于C组和D组。结论 冠桥修复体的边缘与牙周健康密切相关 ,烤瓷冠桥修复体的边缘应尽可能光洁、密合、无悬突 ,伸展度以不超过龈缘下Objective\ Today metal_ceramic restorations are widely accepted in dental practice because of their good aesthetic and biocompatible properties, but there are still several problems to be resolved, among which the influences of their margins on gingival health is noticeable. The purpose of this study was to investigate the influences of metal_ceramic restoration margin on gingival health.Methods\ 129 abutments of metal_ceramic restorations, including their margins′ fitness, location and smoothness were examined and their influences on gingival health were analyzed.Results\ There was a close relation between the metal_ceramic restorations′ margins and the gingival health.Conclusion\ In order to maintain the gingival health, the margins should be smooth, closely fitted, no overhanging and in a moderate location (i.e. not below the gingival more than 1 mm).\;
