种植义齿在外胚叶发育异常患者牙列重建中的应用

Functional reconstruction of dentition of ectodermal dysplasia using implant dentures

目的 探讨种植义齿在外胚叶发育异常（ectodermal dysplasia，ED）患者牙列缺损和（或）缺失重建中应用的可行性、功能及美观效果。方法 依据临床检查及X线检查结果，将种植体植入外胚叶发育异常的患者颌骨内，当种植体与骨发生骨性整合后行义齿修复，并选择适当的附着体以增强义齿的固位。结果 5例患者共植入12颗种植体，在为期6～48个月的临床观察中，除1颗种植体周有轻度软组织炎症外，其他种植体周软组织健康状况良好，全部种植体均形成良好的骨整合，所有患者均认为义齿对美学效果、咀嚼功能、发音等均有明显改善，自信心提高。结论 在外胚叶发育异常患者牙列重建中，种植义齿可达到良好的治疗效果。

Objective To investigate the aesthetic efficacy of dental implant employed to the functional reconstruction of ectodermal dysplasia （ED） patients. Methods Dental implants were inserted into the jaw bone of ED patients according clinical and X-ray examination. The dentures were made after the osseous integration of implants. The proper attachments were employed to increase the retention of the dentures. The aesthetics, denture retention, phonation, mastication, and the health of soft and hard tissues of peri-implant were evaluated in the 6-48 months follow-up period. Results 12 dental implants were inserted into jaw bone in 5 ED patients and all implants were osseointegrated and remained in the 6- 48 months follow-up period. Aesthetics, denture retention, phonation, mastication, and confidence were significantly improved. Conclusions Dental implants can be used to functionally reconstruct the dentition of ED. The aesthetics and functions are improved significantly.
