“…Preliminary impressions are routinely made in dental practice, as they provide the study casts that are used for diagnosis, treatment planning, and the fabrication of custom impression trays 1 . In addition, impressions similar to the preliminary ones are frequently needed for purposes such as constructing an orthodontic device or obtaining the cast of opposing arches 2 . Impression making follows a well‐established protocol, 3 whose main objective is the accurate reproduction of the area to be recorded 4 …”

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.
