摘要:

目的 分析微种植钉辅助上颌快速扩弓在Ⅲ类错𬌗畸形患者中的临床效果。方法 选取邯郸市口腔医院2022年1月至2023年4月诊治的58例Ⅲ类错𬌗畸形患者作为对照组,采用手术辅助上颌快速扩弓治疗,选取邯郸市口腔医院2023年6月至2024年5月收治的58例Ⅲ类错𬌗畸形患者作为观察组,微种植钉辅助上颌快速扩弓治疗,在治疗3个月后拍摄锥形束CT,比较两组患者治疗前后骨性结构、软组织测量结果、咬合功能、扩弓效果及术后并发症发生情况。结果 与术前比较,两组治疗后骨性宽度、上颌牙支抗牙倾斜度均增加(P<0.05);而与对照组比较,观察组鼻腔宽度增加明显,支抗牙倾斜度均减低明显(P<0.05)。治疗后观察组ANB、LI-MP高于对照组,SNB、MP-SN低于对照组,面凸角、鼻唇角高于对照组,颏唇角低于对照组,咬合功能高于对照组(P<0.05)。观察组术后并发症发生率(1.72%)低于对照组(13.79%),差异明显(P<0.05)。结论 微种植钉辅助上颌快速扩弓可取得明显的骨性扩宽效应,促进患者骨性结构改善,改善其面貌形态,提高其咬合功能,可推广应用。

Abstract:

Objective To analyze the clinical outcome of microimplant screw-assisted maxillary rapid arch expansion in patients with Class Ⅲ malocclusion. Methods A total of 58 patients with Class Ⅲ malocclusion treated at Handan Stomatological Hospital from January 2022 to April 2023 were selected as the control group, and surgically assisted rapid maxillary arch expansion treatment was used. A total of 58 patients with Class Ⅲ malocclusion treated at Handan Stomatological Hospital from June 2023 to May 2024 were selected as the observation group, and micro-implant assisted rapid maxillary arch expansion treatment was performed. After 3 months of treatment, cone beam CT was taken to compare the bone structure, soft tissue measurement results, occlusal function, arch expansion effect, and postoperative complications between the two groups of patients before and after treatment. Results The bony width and the tilt of the supported teeth of the maxillary teeth increased in both groups after treatment, compared with the preoperative period(P<0.05). The nasal width of the maxillary first molar in the observation group increased significantly, and the tilt of the supported teeth were all reduced significantly compared with the control group(P<0.05). After treatment, ANB and LI-MP of the observation group were higher than those of the control group; SNB and MP-SN were lower than those of the control group. Facial convexity angle and nasolabial angle were higher than those of the control group; chin-labial angle was lower than those of the control group, and occlusal function was higher than those of the control group(P<0.05). The postoperative complication rate of 1.72% in the observation group was lower than that of 13.79% in the control group, with a significant difference(P<0.05). Conclusion Micro-implant-assisted rapid maxillary arch expansion can achieve obvious bony expansion effect, promote the improvement of the patient’s bony structure, improve their facial morphology, and enhance their occlusal function, which can be promoted and applied.
