Impression making may be complicated in individuals with limited ability to cooperate with caregivers. An alternative technique for obtaining full-arch casts from sectional preliminary impressions is described. The technique is a modification of the procedure advocated for impression making in subjects with limited mouth opening. A pair of partial stock trays is selected to fit the right and left side of the arch. Two sectional irreversible hydrocolloid impressions are made separately. The first cast is placed into the second impression prior to pouring, to obtain a cast of the complete arch. The procedure was used during the treatment of an uncooperative young patient with Lesch-Nyhan Syndrome and provided a simple and reliable means to obtain the diagnostic cast of the mandibular teeth. It is recommended not only for uncooperative patients, but also for patients with special needs; such as those with anatomical restrictions, functional impairment, and movement disorders.
对于那些与护理人员合作能力有限的个体，制取印模可能会很复杂。本文描述了一种从分段初步印模制取全牙弓模型的替代技术。该技术是对为张口受限患者制取印模所倡导的程序的一种改进。选择一对局部成品托盘以适配牙弓的右侧和左侧。分别制取两段不可逆水胶体印模。在灌注之前，将第一个模型放入第二个印模中，以获得完整牙弓的模型。该程序在治疗一名患有莱施-奈恩综合征的不合作年轻患者时使用，为获取下颌牙齿的诊断模型提供了一种简单可靠的方法。它不仅推荐用于不合作的患者，也适用于有特殊需求的患者；例如那些有解剖限制、功能障碍和运动障碍的患者。
