Congenital absence of multiple teeth and poorly developed alveolar ridges are associated with ectodermal dysplasia. Affected patients often require dental prosthetic treatment during their developmental years. Maxillofacial growth and development in a preadolescent female patient with ectodermal dysplasia following oral rehabilitation with maxillary and mandibular endosseous dental implants is reported. Four maxillary and 4 mandibular implants were successfully integrated and restored at 8 years of age. Growth analysis 12 years later revealed that the implants followed maxillary and mandibular growth displacement. Minor impaction of the maxillary implants was observed, and mandibular implants were affected by the mandibular growth rotation, which led to a change in implant inclination. The treatment outcome is compared to similar previously reported studies and cases.
多颗牙齿先天性缺失和牙槽嵴发育不良与外胚层发育不全有关。受影响的患者在发育阶段通常需要进行牙修复治疗。本文报道了一名患有外胚层发育不全的青春期前女性患者在上颌和下颌骨内牙种植体口腔修复后的颌面生长发育情况。在该患者8岁时成功植入并修复了4颗上颌和4颗下颌种植体。12年后的生长分析显示，种植体随着上颌和下颌的生长而移位。观察到上颌种植体有轻微的嵌入，而下颌种植体受到下颌生长旋转的影响，导致种植体倾斜度发生变化。将该治疗结果与先前报道的类似研究和病例进行了比较。
