Patients with ectodermal dysplasia (ED) experience several problems caused by abnormal development and functioning of the head and neck region. In addition to developmental nasal cartilage abnormalities and absence of sweat glands, hair, and eyebrows, edentulism or developmental disorders of teeth (cone-shaped teeth) are commonly observed in these types of patients. ED is also characterized by underdeveloped alveolar ridges, a decreased occlusal vertical dimension, reduced salivary secretion, and dry oral mucosa, which make prosthetic rehabilitation difficult. Few studies of intraosseous dental implant-retained prostheses have described adverse effects on craniofacial growth and esthetic and functional disadvantages, while some researchers have described the advantages of this treatment option as an alternative option in these cases. Due to the associated alveolar bone deficiency, dental mini-implant therapy may be a treatment option for these patients; however, there are isolated cases in the literature regarding the rehabilitation of ED patients with mini-implant-supported overdentures. This clinical report describes the rehabilitation of a 6-year-old child with ED using a maxillary removable partial prosthesis and a mini-implant-retained mandibular overdenture. The clinical and radiographic findings of this prosthetic rehabilitation during the 6-year follow-up are also presented.
患有外胚层发育不全（ED）的患者会经历因头颈部区域发育和功能异常而导致的多种问题。除了发育性鼻软骨异常和无汗腺、毛发和眉毛外，这些患者还常出现无牙（锥形牙）或牙齿发育障碍。ED 的特征还包括牙槽嵴发育不良、咬合垂直距离减小、唾液分泌减少和口腔黏膜干燥，这使得义齿修复变得困难。少数关于骨内牙种植体固位修复体的研究描述了其对颅面生长的不良影响和美观及功能方面的劣势，而一些研究人员则将这种治疗选择描述为这些情况下的替代方案的优势。由于存在相关的牙槽骨缺损，牙种植体迷你支抗治疗可能是这些患者的一种治疗选择；然而，文献中仅有孤立的病例报告了使用迷你种植体支抗义齿修复 ED 患者。本临床报告描述了使用上颌可摘局部义齿和下颌迷你种植体固位覆盖义齿对一名 6 岁 ED 患儿进行的修复治疗。还介绍了该患者在 6 年随访期间进行的这种修复治疗的临床和影像学检查结果。
