[摘要] 目的 研究不同修復材料对口腔修复患者牙周指标的影响。 方法 将2017年1月～2018年4月于本院门诊接受口腔修复治疗的患者90例依据修复材料不同分为二氧化锆全瓷冠组（n=30）、钴铬合金组（n=30）、金沉积组（n=30）。所有患者修复后随访12个月，对比分析三组患者牙周指标改善情况，研究三组患者修复后1年密合度、冠颜色、颈缘染色变化及冠崩瓷、冠折裂发生情况。 结果 修复前，三组PD、SBI、PLI相比，差异无统计学意义（P>0.05）;修复后1年，三组SBI水平上升，且金沉积组与二氧化锆全瓷冠组显著低于钴铬合金组，差异有统计学意义（P<0.05）。修复后1年，金沉积组及二氧化锆全瓷冠组密合度、冠颜色、颈缘染色均优于钴铬合金组，差异有统计学意义（P<0.05）。修复后1年内，三组冠崩瓷、冠折裂发生率相比，差异无统计学意义（P>0.05）。结论 金沉积及全瓷冠口腔修复可起到较好修复效果，可降低对牙周健康的影响，保障口腔环境良好发展。

[Abstract] Objective To study the influence of different restorative materials for periodontal index in patients with prosthodontics. Methods 90 patients who received prosthodontic treatment in the outpatient department of our hospital from January 2017 to April 2018 were divided into zirconium dioxide all ceramic crown group（n=30）， cobalt chromium alloy group（n=30） and gold deposition group（n=30） according to different restoration materials. All patients were followed up for 12 months after restoration， and the improvement of periodontal index in the three groups of patients was compared and analyzed. The changes of fitness， crown color， and marginal staining and the occurrence of crown porcelain collapse and crown fracture in the three groups of patients one year after restoration were studied. Results Before restoration， there was no statistically significant difference among the three groups in PD， SBI and PLI（P>0.05）. One year after restoration， the level of SBI in the three groups increased， and the levels of SBI of the gold deposition group and zirconium dioxide all ceramic crown group were significantly lower than that of the cobalt chromium alloy group， with statistically significant difference（P<0.05）. After the restoration for one year， the density， crown color and neck edge staining in the gold deposition group and zirconia all ceramic crown group were better than those in the cobalt chromium alloy group， and the difference was statistically significant （P<0.05）. After the restoration within one year， there was no significant difference in the incidence of crown fracture between the three groups（P>0.05）. Conclusion Gold deposition and all ceramic crown oral restoration can achieve better restoration effect， reduce the impact on periodontal health and ensure the good development of oral environment.

牙齿损坏或牙齿缺失是常见口腔疾病，由于牙齿损坏、牙齿缺失不仅影响个人形象更威胁患者口腔健康，因此患者普遍选择口腔修复以改善口腔状况[1]。口腔修复是牙齿损坏、牙齿缺失常用治疗方式，主要包括嵌体、义齿、全冠等方式，为口腔医学中重要分支[2]。但口腔修复具有多种不同修复材料，不同修复材料对修复质量具有一定影响，且可能诱发或加深牙周组织炎症反应[3-4]。因此在兼顾性价比、生物相容性、美观度等基础上还需关注修复后口腔健康发展[5]。基于此，本院将使用不同材料进行口腔修复治疗的患者作为研究对象，开展相关对比研究，旨在区分不同口腔修复材料的优劣性，现报道如下。
