Abstract：
OBJECTIVE: This randomized clinical trial aimed to assess the feasibility of computer-assisted open exposure of palatally impacted canines.
METHODS: Patients aged 11-30 years who required orthodontic eruption for the full palatal impaction of their canines were included in this study. Exclusion criteria were psychosocial and dental contraindications of orthodontic treatment, congenital craniofacial disorders, and trauma in the patient\'s history in the vicinity of the surgical site. Virtual planning software was used to register the intraoral scans and cone-beam computed tomography data and to design a surgical template. In the test group, exposure of the canines was guided by a surgical template, whereas in the control group, the surgeon relied on the surgical plan to localize the impacted canine. The success of the intervention, duration of surgery, and complications, including excessive hemorrhage, damage to the canine or neighboring anatomical landmarks, and postoperative inflammation of the surgical site were assessed. Postoperative pain was reported by the patients using the visual analog pain scale (VAS).
RESULTS: Surgery was deemed successful in all patients in both groups. During healing, no complications were observed. The duration of surgery decreased significantly in the test group (4 min 45.1 s ± 1 min 8.4 s) compared to that in the control group (7 min 22.3 s ± 56.02 s). No statistically significant differences were observed between the VAS scores of the two study groups.
CONCLUSIONS: The application of virtual planning and static navigation is a viable approach for the open exposure of palatally impacted canines.
BACKGROUND: NCT05909254.
CONCLUSIONS: Computer-assisted surgery is a feasible method for open exposure of palatally impacted canines, which decreases the duration of surgery compared to the freehand method.

摘要：
目的：这项随机临床试验旨在评估计算机辅助开放暴露于腭受累犬的可行性。
方法：这项研究纳入了年龄在11-30岁之间的患者，这些患者需要正畸萌出，因为他们的犬科动物的全腭嵌塞。排除标准是正畸治疗的社会心理和牙科禁忌症，先天性颅面疾病,和患者病史中的创伤在手术部位附近。虚拟计划软件用于配准口内扫描和锥形束计算机断层扫描数据并设计手术模板。在测试组中，犬的暴露是由手术模板引导的，而在对照组中，外科医生依靠手术计划定位受影响的犬。干预的成功,手术持续时间,和并发症，包括过度出血,对犬科动物或邻近解剖标志的损害，并评估手术部位的术后炎症。患者使用视觉模拟疼痛量表（VAS）报告术后疼痛。
结果：两组患者均认为手术成功。在治疗过程中,未观察到并发症。与对照组（7min22.3s±56.02s）相比，试验组（4min45.1s±1min8.4s）的手术时间显着减少。两个研究组的VAS评分之间没有观察到统计学上的显着差异。
结论：虚拟计划和静态导航的应用是开放暴露于pa受累犬的可行方法。
背景：NCT05909254临床意义：计算机辅助手术是一种可行的方法，用于开放暴露于pa受累的犬科动物，与徒手法相比，缩短了手术时间。
