摘要/Abstract

摘要： 目的：观察分裂桩冠和分裂桩核冠修复低（牙合）龈距离且根分叉较大后牙的临床效果，阐明其应用优势并分析其改进方法。方法：选取29例患者的49颗完善根管治疗的低（牙合）龈距离磨牙残根，参考患者意愿随机分为分裂桩冠组23颗和分裂桩核冠组26颗，分别进行分裂桩冠或分裂核桩冠修复，观察2组患牙术后12和24个月后的修复成功率，比较戴牙12个月后龈沟液中基质金属蛋白酶8（MMP-8）含量。结果：分裂桩冠组在治疗后12和24个月的修复成功率分别为95.7%和82.6%，修复成功率比较差异无统计学意义（P > 0.05）；分裂核桩冠组在治疗后12和24个月的修复成功率分别为84.6%和52.2%，修复成功率比较差异有统计学意义（P < 0.05）。在治疗后24个月，分裂桩冠组的修复成功率明显高于分裂核桩冠组（P < 0.05）；2组患者龈沟液中MMP-8含量比较差异无统计学意义（P > 0.05）。结论：分裂桩冠用于低（牙合）龈距离磨牙残根修复在24个月随访期内临床效果明显优于分裂核桩冠，针对性地加以改进有助于提高临床修复成功率。

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 post-core crown. Targeted improvement will help to improve the clinical success rate.

Key words: split post crown, split post-core crown, low occlusogingival distance, root furcation, molar
