摘要： 目的对3D打印种植导板和传统种植导板在多牙缺失种植中的效果进行观察,并评价患者的满意度。方法30例（83颗牙）缺牙需种植的患者,用随机数字表法分为传统种植导板组（CIT组,15例,42颗牙）和3D打印种植导板组（TDPIT组,15例,41颗牙）,CIT组患者采用传统种植导板,TDPIT组患者采用3D打印种植导板,比较2组患者植入种植体的颈部和尖部偏离值、种植体角度偏离值及角度满意度,术后1年牙周袋探诊深度、骨吸收情况及种植成功率。通过满意度问卷调查,比较2组患者对牙种植效果的满意度。采用SPSS19.0软件包对数据进行统计学分析。结果TDPIT组种植体颈部和尖部在近远中向、颊舌向和垂直向3个方向的偏离值以及在近远中向和颊舌向2个方向的平均角度偏离值均显著小于CIT组（P<0.05）,且TDPIT组种植体在近远中向和颊舌向2个方向的角度满意度显著高于CIT组（P<0.05）。2组患者术后1年种植体牙周袋探诊深度及骨吸收情况无显著差异（t=1.144,P=0.256;t=1.063,P=0.291）。2组患者术后3个月和6个月种植成功率无显著差异（P>0.05）,但术后随访9个月和1年,TDPIT组种植成功率显著高于CIT组（90.48%∶100%,χ2=4.102,P=0.043）。满意度问卷调查显示,TDPIT组患者对种植的满意度显著高于CIT组（86.67%∶53.33%,χ2=3.968,P=0.046）。结论3D打印种植导板植入的种植体精度、种植成功率和患者满意度优于传统种植导板,适合推广应用。

Abstract: To study the value and satisfaction of three-dimensional printing implant template and conventional implant template in multi-tooth dental implantation. METHODS: Thirty cases (83 teeth) with missing teeth needing to be implanted were randomly divided into conventional implant template group (CIT group, 15 cases, 42 teeth) and 3D printing implant template group (TDPIT group, 15 cases, 41 teeth). Patients in CIT group were operated by using conventional implant template, while patients in TDPIT group were operated by using three-dimensional printing implant template. The differences of implant neck and tip deviation, implant angle deviation and angle satisfaction between the two groups were compared. The difference of probing depth and bone resorption of implant were compared 1 year after operation between the two groups. The difference of success rate and satisfaction of dental implantation were compared 1 year after operation between the two groups. SPSS19.0 software package was used for statistical analysis. RESULTS: The deviation direction of the neck and the tip in disto-mesial, bucco-palatal, vertical direction and angle of implants in disto-mesial and bucco-palatal direction in TDPIT group were significantly lower than in CIT group (P<0.05), and angle satisfaction of implants in disto-mesial and bucco-palatal direction in TDPIT group were significantly higher than in CIT group (P<0.05). There was no significant difference between the two groups in the probing depth and bone resorption of implants 1 year after operation (P>0.05). The difference of the cumulative success rate in dental implantation at 3 months and 6 months between the two groups were not significant (P>0.05), but the cumulative success rate of TDPIT group was significantly higher than CIT group at 9 months and 1 year (90.48% vs 100%, χ2=4.102, P=0.043). The patients' satisfaction rate of dental implantation in TDPIT group was significantly higher than in CIT group (86.67% vs 53.33%, χ2=3.968, P=0.046). CONCLUSIONS: Using three-dimensional printing implant template can obtain better accuracy of implant, higher implant success rate and better patients' satisfaction than using conventional implant template. It is suitable for clinical application.
