Ectrodactyly-ectodermal dysplasia-cleft lip/palate (EEC) syndrome is a rare genetic disorder that affects ectodermal derived structures, including teeth, nails, hair, and sweat glands. Prosthetic rehabilitation of patients with EEC syndrome is essential towards improving their overall quality of life.
In the case shown, a telescopic retained overdenture was made on the lower jaw based on digital impression of a patient with EEC syndrome associated with cleft lip and cleft palate. Due to the congenital anomalies and limited mouth opening, the impression was taken with intraoral scanner, and after designing the telescopes on the digital model, the primary and secondary telescopes were confectioned by selective laser sintering.
Combining digital dental technology and conventional clinical prosthetic treatment methods, results in a well-functioning overdenture even in such complicated situations. The prosthodontic rehabilitation of patients with ECC helps to restore the masticatory and phonetic functions, increases the patient's self-esteem, and prevents further psychological trauma caused by hypodontia.
外胚层发育不良-外胚层-唇/腭裂（EEC）综合征是一种罕见的遗传疾病，影响外胚层衍生结构，包括牙齿、指甲、毛发和汗腺。EEC 综合征患者的修复体修复对于提高他们的整体生活质量至关重要。
在本例中，根据 EEC 综合征伴唇裂和腭裂患者的数字印模，在下颌制作了可摘式套筒保持覆盖义齿。由于先天异常和张口受限，采用口腔内扫描仪进行印模，在数字模型上设计望远镜后，通过选择性激光烧结制作初级和次级望远镜。
将数字牙科技术与传统临床修复治疗方法相结合，即使在复杂情况下也能制作出功能良好的覆盖义齿。ECC 患者的修复体有助于恢复咀嚼和语音功能，增加患者的自尊心，并防止因缺牙引起的进一步心理创伤。
