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.
