ABSTRACT:
The base (11) of a template forming device (10) has a planar, upper surface (12) onto which a plurality of orthogonal grooves (14 and 15) are recessed. A foam mixture is introduced into a container means (20) received on the base (11), and a plurality of restraining means in the form of slats (18) are insertably received within selected grooves (14 and 15) to confine the foaming action within the container means (20) and to direct it against a selected portion of the anatomy so that when the foam is fully risen and cured a template (40) is provided which can be repeatedly used accurately to reposition and support that portion of the patient's anatomy.
