摘要： 目的:开发3D打印正畸微小种植体导板,以应用于正畸临床植入微小种植体支抗,提高植入准确性。方法:对需植入种植体支抗的错合畸形患者进行CBCT扫描与口内扫描,将DICOM格式存储的CT数据与口内扫描的STL数据导入3Shape Implant Studio软件中,进行对齐重合,重建上下颌骨三维模型。在重建的上下颌骨模型上,根据微小种植体垂直骨面,不损伤牙根、上颌窦等组织,并尽量与牙根平行的要求,设计出种植导板,使用Formlabs2 3D打印机打印导板。术中通过导板确定位置、角度,植入微小种植体,术后CT评估种植体位置和植入角度。结果:经过CBCT验证,术中使用此新型正畸微小种植体导板,微小种植体位置和角度准确,术后3个月微小种植体未松动脱落。结论:开发和研制新型正畸微小种植体导板,提高微小种植体植入位置和角度的准确性,防止损伤牙根等组织结构,提高种植体稳定性。

Abstract: Objective: To develop a 3D printed orthodontic microimplant template which could be applied in clinical orthodontic implantation of microimplant anchorage and improve the implantation accuracy. Methods: The patients needed to be implanted microimplant anchorage were sent for CBCT and intraoral scan. The CT data stored in DICOM format and STL data scanned with intraoral scan were imported into 3Shape Implant Studio for fusion, so as to reconstruct the 3D model of maxillary and mandible bone. On the maxillary and mandible bone model reconstructed, the implant guide plate was designed according to the requirements of vertical bone surface of the microimplant, i.e. no damage to the root, maxillary sinus and other tissues, and as far as possible parallel to the root of the tooth, and the guide plate was printed with Formlabs2 3D printer. During the operation, the position and angle of the implant were determined by the guide plate, and the microimplant was implanted through the guide tube of the plate. After operation, the patients should take CBCT scanning that was used to evaluate the position and angle of the implant. Results: It was proved by CBCT that when the new type of orthodontic microimplant template was used during the operation, the position and angle of the microimplant were accurate and the microimplant did not loosen and fall out 3 months after the operation. Conclusion: 3D printed orthodontic microimplant guide plate was developed to improve the accuracy of implant placement and angle, prevent tooth root damage, and improve implant stability.
