摘要： 目的：评价生物导向制备技术（biologically oriented preparation technique,BOPT)与常规牙体预备在全冠修复中的应用效果。方法：选择2020年1月—2022年11月收治的93例全冠修复患者,根据牙体制备技术分为试验组和对照组,对照组采用常规牙体预备(46例74 颗牙),试验组采用BOPT(47例75颗牙)。治疗后3个月、6个月、1年和2年,评估患者牙周健康指标[菌斑指数（plaque index,PI）、牙龈指数（gingival index,GI）、牙周探诊深度（probing depth, PD）和牙龈厚度（gingival thickness,GT）],比较并发症发生情况和患者满意度。结果：对照组PI随时间延长而增加,1年时达到最高值（2.20±0.57）,2年时下降到（1.70±0.66）。试验组PI第3个月时达到最高值（2.61±0.52）,6个月时减少,1年时下降至接近治疗前,2年后显著低于治疗前（P<0.001）。两组GI随时间延长而下降,试验组治疗后6个月、1年和2年的GI显著低于对照组（P<0.001）。两组PD随时间延长而下降,对照组治疗后6个月时升高,试验组治疗后6个月、1年和2年的PD显著低于对照组（P<0.001）。两组颊侧GT随时间延长而下降,试验组治疗后6个月、1年和2年的GT显著低于对照组（P<0.05）。试验组生物并发症发生率（2.67%）显著低于对照组（10.81%）（P<0.05）,两组机械并发症发生率相比无显著差异（P>0.05）,试验组并发症总发生率（4.00%）显著低于对照组（14.86%）（P<0.05）。试验组满意度各项评分和总分显著高于对照组（P<0.05）。结论：BOPT用于全冠修复可降低PI、GI和PD,增加GT,降低并发症发生率并提高患者满意度。

Abstract: PURPOSE: To evaluate the value of biologically oriented preparation technique and conventional dental preparation in total crown restoration. METHODS: A total of 93 patients who underwent total crown restoration from January 2020 to November 2022 were selected, and were divided into experimental group and control group according to different dental preparation techniques. The control group was treated with conventional dental preparation (46 cases, 74 teeth), while the experimental group was treated with BOPT (47 cases, 75 teeth). Periodontal health indicators [plaque index (PI), gingival index (gingival index), probing depth (PD) and gingival thickness (GT)] were evaluated at 3 months, 6 months, 1 year and 2 years after treatment. The incidence of complications and patients' satisfaction were compared. RESULTS: In the control group, PI increased with time, reaching the highest value (2.20±0.57) at 1 year and decreasing to (1.70±0.66) at 2 years. PI of the experimental group reached the highest value (2.61±0.52) at the 3rd month, decreased at the 6th month, decreased to close to before treatment at the 1st year, and was significantly lower than before treatment at the 2nd year(P<0.001). The GI of the two groups decreased with the extension of time, and the GI of the experimental group at 6 months, 1 year and 2 years after treatment was significantly lower than that of the control group (P<0.001). The PD of the two groups decreased with the extension of time, and the PD of the control group increased at 6 months after treatment, and the PD of the experimental group was significantly lower than that of the control group at 6 months, 1 year and 2 years after treatment (P<0.001). Buccal GT of the two groups decreased with the extension of time, and the GT of the experimental group at 6 months, 1 year and 2 years after treatment was significantly lower than that of the control group (P<0.05). The incidence of biological complications in the experimental group (2.67%) was significantly lower than that in the control group (10.81%)(P<0.05). There was no significant difference in the incidence of mechanical complications between the two groups (P>0.05). The total complication rate of the experimental group (4.00%) was significantly lower than that of the control group (14.86%)(P<0.05). The scores and total scores of satisfaction of the experimental group were significantly higher than those of the control group (P<0.05). CONCLUSIONS: BOPT for total crown repair can reduce PI, GI and PD, increase GT, reduce complications and improve patients' satisfaction.
