纯钛铸造分裂桩冠修复低(牙合)龈距离且根分叉较大磨牙的临床效果评价
Evaluation on clinical effect of cast pure titanium split post crown restoration of molars with low occlusogingival distance and large root furcation
摘要
Abstract
Objective:To observe the clinical effects of split post crown and split post-core crown in restoring the molars with low occlusogingival distance and large root furcation,and to clarify its advantages and analyze its improvement methods.Methods:Forty-nine molars of twenty-nine patients,which had been completely treated with root canal therapy,were restored by split post crown or split post-core crown according to their wills.Split post crown was used in twenty-three cases,and split post core crown was applied in the other twenty-six cases.The clinical effects of the patients in two groups were observed after 12 and 24 months follow-up.The levels of MMP-8 in gingival crevicular fluid were checked and compared 12 months after restoration.Results:The restoration success rates of split post crown were 95.7％ after 12-month treatment and 82.6 ％ after 24-month treatment,respectively;there was no significant difference between them (P＞ 0.05).The success rates of split post-core crown were 84.6％ after 12-month treatment and 52.2％ after 24-month treatment,respectively;there was significant difference between them (P＜0.05).The success rate of split post crown was significantly higher than that of split post-core crown after 24-month treatment (P＜0.05).The levels of MMP-8 in gingival crevicular fluid of the patients were close to each other,there was no statistical significance (P＞0.05).Conclusion;The split post crown shows better clinical effect in restoring the molars with low occlusogingival distance in 24 months than split postcore crown.Targeted improvement will help to improve the clinical success rate.关键词
