目的 近年来，微种植体在正畸领域越来越受欢迎。微型植入物主要放置在关键解剖结构（例如牙根）可能受损的复杂部位，因此在放置之前需要精确的手术计划。本报告的目的是介绍一种新开发的技术，用于在根间区域放置微型植入物并评估其准确性。材料和方法 使用研究人员制作的射线照相模板和胶片支架对计划的放置部位进行射线照相。将所得的射线照片剪下来并附着到射线照相模板上，以制作手术模板来指导微植入物的放置。 41 名患者参加了这项研究，其中包括 15 名男性和 26 名女性，年龄从 21 岁到 29 岁不等。在牙弓的一侧，这种新技术用于种植体植入，而在另一侧，则使用了 Maino 及其同事报告的既定方法（即控制技术）。结果 41 名患者的根间总共放置了 116 个宽 2 mm、长 9 mm 的微型种植体。对照组 58 个微型植入物中有 12 个未能成功植入，而测试组 58 个微型植入物中有 2 个未能成功植入。统计分析表明，两种技术的成功率存在显着差异（P < .05）。讨论 骨量的术前诊断以及将信息传输到手术部位对于微种植体植入至关重要。为手术目的而修改的射线照相模板具有将射线照相信息直接传输到手术部位的优点。结论 这项研究虽然在某些方面存在局限性，但表明使用所描述的新开发技术可以改善微种植体的放置。
PURPOSE In recent years, microimplants have gained popularity in orthodontics. Microimplants are primarily placed in complex sites where critical anatomic structures, such as roots of teeth, may be damaged, so precise surgical planning is required prior to placement. The goal of this report was to introduce a newly developed technique for the placement of microimplants in interradicular areas and evaluate its accuracy. MATERIALS AND METHODS The planned placement site is radiographed using a radiographic template and film holder fabricated by the investigators. The resultant radiograph is clipped and attached to the radiographic template to make a surgical template to guide the placement of the microimplant. Forty-one patients, 15 men and 26 women ranging in age from 21 to 29 years, were enrolled in this study. On 1 side of the arch, this novel technique was used for implant placement, and on the other side, an established method reported by Maino and associates (i.e., the control technique) was used. RESULTS A total of 116 microimplants 2 mm wide and 9 mm long were placed interradicularly in 41 patients. Twelve of 58 microimplants were placed unsuccessfully in the control group, versus 2 of 58 in the test group. Statistical analysis showed that there was a significant difference between the 2 techniques in terms of success rate (P < .05). DISCUSSION Presurgical diagnosis of bone quantity and transfer of the information to the surgical sites are vital in microimplant placement. Radiographic templates modified for surgical purposes have the advantage of transferring radiographic information directly to the surgical site. CONCLUSION This study, although limited in some respects, demonstrated that microimplant placement can be improved using the newly developed technique described.
