文题释义:
3D打印技术:属快速成型技术,主要以数字模型文件作基础,利用塑料或粉末状金属等可黏合材料经逐层打印方式构成物体,已逐渐在口腔种植、口腔正畸、口腔修复、口腔外科及口腔内科中得到普及应用。
3D打印复合型种植导板的优势:①适应证更为广泛,既往种植导板无法于种植手术前修整牙槽骨,因此在牙槽嵴顶骨宽度不足患者中无法取得良好效果,而3D打印复合型种植导板利于参照患者具体状况,于固定导板后对个别术区实施牙槽骨修整或翻瓣,以此扩大手术适应证;②制作周期较短,传统种植导板需配套专门手术盒,制作周期较长,过程较为繁琐,而3D打印复合型种植导板仅需通过3D打印技术便能快速将导板个性化数据模型转为树脂型实体模型。
 
 
背景:目前3D打印技术为最先进的一种工业制造技术,基于3D打印技术的外科导板主要由树脂制成,其精准度存在较大提升空间,但临床关于金属所制种植外科导板应用价值的报道研究较少。
目的:探讨3D打印复合型种植导板在游离端牙缺失种植修复中的应用价值。
方法:纳入64例游离端牙缺失患者进行前瞻性研究,随机分为对照组(n=32)与研究组(n=32),分别采用传统种植导板和3D打印复合型种植导板进行种植修复,修复后3-6个月进行牙冠修复,牙冠修复后6个月,拍摄锥形束CT,对比两组种植体尖部与颈部偏离值(包括垂直向、颊舌向、近远中向);牙冠修复后随访6个月,对比两组治疗成功率、咀嚼率;牙冠修复后随访1年,对比两组患者治疗满意度。

结果与结论:①研究组与对照组治疗成功率、咀嚼率比较差异无显著性意义(98.7%,95.6%;97.4%,97.1%,P > 0.05);②研究组种植体尖部垂直向、颊舌向、近远中向偏离值小于对照组(P < 0.05);研究组种植体颈部垂直向、颊舌向偏离值与对照组比较差异无显著性意义(P > 0.05),种植体颈部近远中向偏离值小于对照组(P < 0.05);③研究组与对照组患者治疗满意度比较差异无显著性意义(94%,91%,P > 0.05);④结果表明,采用3D打印复合型种植导板在游离端牙缺失种植修复具有较高应用价值,可在保证治疗效果及患者满意度的基础上减小种植体偏移。

Abstract:

BACKGROUND: Three-dimensional (3D) printing technology is currently one of the most advanced industrial manufacturing technologies. The surgical template prepared based on the 3D printing technology is mainly made of resin, and a great improvement in its accuracy is required. However, the clinical application of the surgical template made of metal is rarely reported.

OBJECTIVE: To evaluate the clinical value of 3D-printing implant template in the restoration of free-end missing teeth.
METHODS: A prospective study was conducted in 64 enrolled patients with free end-tooth defects. All the patients were randomly assigned to receive traditional implant template (control group, n=32) or 3D-printing implant template (study group, n=32), and 3-6 months later, the patients were subjected to crown restoration. At 6 months after crown restoration, cone beam computed tomography was performed to compare the deviation of the implant tip and neck (including vertical, buccolingual, mesial-distal). Success rate and chewing rate were compared between the two groups at 6 months after crown restoration; patient satisfaction assessment was done and compared between the two groups at 1 year after crown restoration.

RESULTS AND CONCLUSION: There were no significant differences between the two groups in the success rate and chewing rate (98.7% vs. 95.6%; 97.4% vs. 97.1%, P > 0.05). The vertical, buccolingual, mesial-distal deviations of the implant tip were significantly lower in the study group than the control group (P < 0.05), while there was no difference in the vertical and buccolingual deviations of the implant neck between the two groups (P > 0.05), and the mesial-distal deviation of the implant neck was significantly lower in the study group than the control group (P < 0.05). In addition, there was no difference in the patient satisfaction between the study and control groups (94% vs. 91%,  P > 0.05). To conclude, the 3D printing implant template can effectively reduce implant excursion based on the assurance of therapeutic efficacy and patient satisfaction, which is of great significance in the restoration of free-end tooth loss.
