The surgical and prosthodontic treatment for a 22-year-old man with ectodermal dysplasia is described and illustrated. He had never managed to wear complete dentures, and implant-retained or implant-supported prostheses were indicated. However, the placement of conventional maxillary endosseous implants was contraindicated. A novel surgical template with double sleeves was used to guide osteotomies for 4 zygomatic implants used with an unloaded, one-stage approach. After confirming osseointegration, prosthetic rehabilitation began with an interim implant-supported fixed prosthesis to evaluate esthetics, phonetics, and hygiene maintenance. Clinical challenges included lip biting and speech articulation.
本文介绍并图示了一位 22 岁的外胚层发育不全患者的外科和修复治疗。他从未成功佩戴过全口义齿，因此需要使用种植体固位或支持的修复体。然而，常规的上颌窦内种植体放置是禁忌的。使用带有双套管的新型外科模板引导截骨术，以植入 4 枚颧骨种植体，采用非负重的一期手术方法。确认骨整合后，开始进行修复体的临时植入固定修复，以评估美观、语音和口腔卫生维护。临床挑战包括嘴唇咬伤和言语发音。
