For a long time the dental treatment of choice for mentally handicapped patients was extraction of teeth due to the lack of oral hygiene. Recent studies show the possibilities of restorative and prosthodontic treatment even in this group of patients. The records of 58 patients of a psychiatric clinic treated with 84 telescopic overdentures were examined. The highest survival rates after 7 years were in the light mentally retarded group with 86% and the overdentures with 3 anchor teeth with 81%. Schizophrenic patients and overdentures with only one anchor tooth presented only 29% and 37% survival respectively. It can be concluded that the number of anchor teeth and the kind of mental illness should be considered when planning treatment for mentally handicapped patients with overdentures.
长期以来，由于缺乏口腔卫生护理，智障患者首选的牙科治疗方法是拔牙。最近的研究表明，即使是这类患者，也有可能进行修复和义齿修复治疗。对一家精神病诊所58例接受84副套筒冠覆盖义齿治疗的患者记录进行了检查。7年后，轻度智力障碍组的存留率最高，为86%，3颗基牙的覆盖义齿存留率为81%。精神分裂症患者和仅有1颗基牙的覆盖义齿存留率分别仅为29%和37%。可以得出结论，为智障患者计划覆盖义齿治疗时，应考虑基牙数量和精神疾病类型。
