【摘要】：目的:比较三维打印数字化无牙颌个别托盘与传统无牙颌个别托盘的技工制作用时及临床操作用时,从临床时间花费角度对数字化个别托盘进行适用性验证。方法:招募20名无牙颌患者进行前瞻性、单盲、自身随机对照临床试验,每人均采用北京大学口腔医院功能易适性数字化全口义齿(functional suitable denture,FSD)系统修复方式及传统全口义齿修复方式制作无牙颌个别托盘,将利用两种方式制作的个别托盘制取终印模后制作全口义齿,记录技工制作用时及临床操作用时。结果:三维打印数字化无牙颌个别托盘与传统无牙颌个别托盘的制作平均人工用时分别为(28.6±2.9)min、(31.1±5.7)min,两者差异有统计学意义(P0.05)。分别用三维打印数字化无牙颌个别托盘与传统无牙颌个别托盘制取终印模的临床操作平均用时为(23.4±11.5)min、(25.4±13.0)min,两者差异有统计学意义(P0.05)。结论:三维打印数字化无牙颌个别托盘的技工制作用时及临床操作用时均小于传统无牙颌个别托盘,采用三维打印数字化无牙颌个别托盘制作全口义齿能够节约技工的制作时间及临床操作用时,且由于其不需要灌注初印模,可节省印模材料及模型材料,在全口义齿修复治疗中,是值得临床推广的制作无牙颌个别托盘的方式。
[Abstract]:Objective: to compare the working time and clinical operation time between 3D printing digital individual pallet and traditional edentulous individual pallet, and verify the applicability of digital individual pallet from the point of view of clinical time.Methods: twenty patients with edentulous jaw were recruited for prospective, single-blind, self-randomized controlled clinical trial.Dental pallet was made by using functional suitable denture system and traditional complete denture system in Peking University Stomatology Hospital.The complete dentures will be made after the final impression of individual trays made in two ways, and the time used by the craftsmen and the clinical operation will be recorded.Results: the average artificial time of digital edentulous individual pallet and traditional edentulous individual pallet was 28.6 卤2.9 min, 31.1 卤5.7 min, respectively. The difference between them was statistically significant (P 0.05).The average clinical operation time for the final impression made from the digital edentulous individual pallet and the traditional edentulous individual tray was 23.4 卤11.5min, 25.4 卤13.0min, respectively. The difference was statistically significant (P 0.05).Conclusion: the working time and clinical operation time of 3D printing digital edentulous individual pallet are smaller than that of traditional edentulous individual pallet.Making complete denture with three dimensional printing and digitizing individual pallet of edentulous jaw can save the time of craftsman's making and clinical operation, and because it does not need to infuse initial impression, it can save impression material and model material.In the treatment of complete denture, it is worth popularizing to make individual pallet of edentulous jaw.
