[摘要]目的：根据最新美国公共卫生协会评价标准(USPHS)研究两种修复缺损牙体方法的临床效果。方法：选取2015年10
月-2017年10月来笔者医院就诊的牙体大面积缺损的123例患者（共145颗患牙），随机分为对照组62例和观察组61例。对照
组采用传统方法桩核冠进行修复，观察组应用数字化椅旁CAD系统制作高嵌体进行修复，根据USPHS标准对患者修复治疗后的
第6、12个月修复体情况进行评价，患者和口腔医师进行修复体满意度调查。结果：两组修复后大多数患者的效果均为“A”
级，与对照组比较，观察组6个月和12个月的牙龈健康、12个月的边缘适合性及术后敏感性均明显改善(P ＜0.05)，其余指标
比较无统计学差异(P ＞0.05)；患者自身评价：与对照组比较，观察组的舒适度明显增强(P ＜0.05)；口腔医师评价：与对照
组比较，观察组边缘密合性满意度较高(P ＜0.05)。结论：数字化椅旁CAD系统制作高嵌体对修复牙体大面积受损效果良好，
提升了临床疗效，数字化椅旁即刻全瓷修复技术可临床推广应用。

Abstract:: Abstract: Objective To study the clinical effect of 2kinds of dental restoration based onAmerican society of public health
evaluation criteria (USPHS). Methods 122 cases inpatients with 145 cases massive dental defects enrolled into our hospital
from October 2015 to October 2017 were selected and dividedrandomly into 2 groups: 62 cases in the control group and
61 cases in the observation group. The control group accepted the routine treatment and the observation accepted digital
CAD system. The restoration of the prosthesis at the 6th and 12th month after treatment was evaluated by the USPHS. The
satisfaction survey of the prosthesis with the patients and the dentists was conducted and compared within 2 groups. Results
Most of the patients in the 2 groups had a grade ‘A’ after treatment. Compared with the control group, the gingival health of 6
months and 12 months after treatment and the edge suitability and sensitivity after 12 months in the observation had improved
in the observation group(P ＜0.05). There was no statistical difference in other indicators within 2 groups 6 months and 12
months after treatment (P ＞0.05). Compared with the control group, the cases of patient’s self-evaluation showed comfort
had significantly increased in the observation group(P ＜0.05).Compared with the control group, the dentists’satisfaction had
increased in the observation group (P ＜0.05). Conclusion The Cerec AC system combined with the IPS e.max CAD series
magnetic block has a good effect on dental restoration The digital porcelain immediate repairing technique is worthy of clinical
application.
