目的:分析应用排龈线进行排龈在前牙美学修复中全瓷冠粘固后对牙周组织的影响。方法:通过对前牙美学修复中全瓷冠粘固前应用排龈线排龈组和不排龈组牙周组织状况进行追踪观察并进行统计学分析。结果:全瓷冠修复后排龈组牙周组织的健康状况优于不排龈组,差异有统计学意义(P<0.05)。结论:前牙全瓷冠粘固前应用排龈线进行排龈,可以有效预防牙周疾病的发生。
OBJECTIVE: To analyze the effect of gingival retraction on the periodontal tissue after all-ceramic crowns were fixed in the aesthetic restoration of anterior teeth. Methods: The periodontal tissues of gingival retraction and gingival retraction before an all-ceramic crowns in the restoration of anterior teeth were observed and analyzed statistically. Results: The health status of periodontal tissue in allograft group was better than that in irrigating group (P <0.05). Conclusion: The application of gingival retraction line for gingival retraction before the all-ceramic crowns of anterior teeth can effectively prevent the occurrence of periodontal disease.
