An alternative impression technique for individuals with special care needs

Abstract

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.

Effective treatment of self‐injurious oral trauma in Lesch–Nyhan syndrome: a case report

“…To obtain the mandibular impression, a sectional impression technique was employed. Two sectional impressions were made, one for each side of the mouth, using partial stock trays (39). The impressions were afterwards combined and poured to provide the mandibular cast (Fig.…”
