The treatment of choice in cases of avulsed permanent teeth is the immediate reimplantation. However, this conduct does not always work favorably, either by failures in the initial approach or by inappropriate interventions. In this sense, the aim of this study is to present an alternative prosthetic rehabilitation with the use of orthodontic mini-implants in the anterior region. This case reports a ten-year-old child with history of avulsion of superior central incisors. The therapeutic approach was planned to promote physiological teeth contacts and acceptable esthetics and phonetics. First, the occlusal-gingival insertion of two orthodontic mini-implants was performed in the alveolar ridge, and, immediately after that, two provisional crowns were attached to the implants. The interventions achieved satisfactory cosmetic and functional results. After one-year follow-up, the adjacent periodontal tissues remained without signs and/or symptoms of inflammation. The provisional crowns presented no mobility and fractures. During radiographic examination, a healthy bone tissue appearance was observed. The simplicity of mini-implant installation makes them a promising alternative for temporary prosthetic rehabilitation of patients undergoing growth and development. The technique provides positive aesthetic and functional results that may reflect on self-esteem and social inclusion of children and adolescents.
恒牙脱位病例的首选治疗方法是立即再植。然而，这种做法并不总是能取得良好效果，原因可能是初始处理失败或干预不当。从这个意义上说，本研究的目的是介绍一种在前牙区使用正畸微型种植体进行修复的替代方法。本病例报告了一名10岁儿童，有上颌中切牙脱位史。治疗方案旨在促进生理性牙齿接触以及达到可接受的美观和语音效果。首先，在牙槽嵴进行两个正畸微型种植体的龈向植入，之后立即在种植体上安装两个临时冠。这些干预措施取得了令人满意的美容和功能效果。经过一年的随访，相邻牙周组织未出现炎症体征和/或症状。临时冠没有松动和折断。在影像学检查中，观察到骨组织健康。微型种植体安装简便，使其成为生长发育中患者临时修复的一种有前景的替代方法。该技术提供了积极的美学和功能效果，可能会对儿童和青少年的自尊和社会融入产生影响。
