Impacted teeth are a fairly common defect with the incidence ranging from 2.9 to 13.7%. Evaluation of the efficacy and safety of various treatment modalities in patients with impacted teeth within the frontal segment of the maxilla. The retrospective evaluation covered treatment outcomes in 81 patients with impacted teeth within the aesthetic segment. The subjects were divided into 3 groups. Patients with the impacted tooth uncovered and orthodontically repositioned in the arch were assigned to group 1. Group 2 consisted of patients with the impacted tooth qualified for extraction and the gap augmented and restored with an implant. Group 3 included subjects, who underwent en-bloc autotransplantation of the impacted tooth. In 38 group 1 subjects 47 teeth were uncovered with a mean efficacy of 58.1% (96.3% and 70% in patients below 18 yoa and adults, respectively). The excellent aesthetic treatment outcome was obtained in 75% and good in 25% of patients. In group 2 twenty-six adult subjects were treated with 100% efficacy. In 65.4% of patients, augmentation with a bone block was performed and in the remaining 34.6%, implantation and augmentation with bone granulate. In 88.3% subjects a satisfying treatment outcome was obtained. In group 3 eighteen teeth in a block were grafted with the efficacy of 88.9%. Excellent aesthetics was obtained in 56.25% of cases and good in 31.25%. Orthodontic repositioning of the impacted teeth in the arch in adult patients bears the risk of failure. Surgical treatment modalities in impacted teeth are effective and provide high aesthetics of the treatment outcome improved by prior orthodontic treatment of the concomitant malocclusion and augmentation of the vertical bone atrophy before implantation.
埋伏牙是一种相当常见的缺陷，发病率为 2.9%至 13.7%。评估各种治疗方法在前上颌骨前节埋伏牙患者中的疗效和安全性。回顾性评估涵盖了 81 例美学段埋伏牙患者的治疗结果。将患者分为 3 组。将埋伏牙暴露并在牙弓中重新定位的患者归入第 1 组。第 2 组由适合拔牙且间隙用种植体扩增和修复的埋伏牙患者组成。第 3 组包括接受埋伏牙整块自体移植的患者。在 38 例第 1 组患者中，有 47 颗牙齿被暴露，有效率为 58.1%（18 岁以下和成人患者分别为 96.3%和 70%）。75%的患者获得了极好的美学治疗效果，25%的患者获得了良好的美学治疗效果。第 2 组 26 例成年患者的治疗有效率为 100%。在 65.4%的患者中，进行了骨块扩增，在其余 34.6%的患者中，进行了骨颗粒植入和扩增。88.3%的患者获得了满意的治疗效果。第 3 组 18 颗牙以 88.9%的疗效被移植。56.25%的病例获得了极好的美学效果，31.25%的病例获得了良好的美学效果。在成年患者中，将埋伏牙在牙弓中重新定位存在失败的风险。埋伏牙的手术治疗方法是有效的，并且可以提供高美学的治疗效果，这种效果是通过先前对伴随的错牙合畸形的正畸治疗和在植入前对垂直骨萎缩的扩增来改善的。
