ABSTRACT:
A tooth shade guide casting form for in-office preparation of shade samples of tooth color restoration material (TCRM) to be utilized by dentists in the restoration of a patient's tooth surface. The invention includes a handle, preferably of thin transparent plastic, and a detachable bowl disposed from one end of the handle. The bowl is preferrably the size and shape of a human tooth and is adapted to receive a quantity of photocurable TCRM to be hardened therein. After hardening, the bowl is detached from the handle, leaving the cured TCRM shade sample attached to the first end of the handle. Such samples, having the contour of the bowl, are then used by dentists in selecting the properly colored TCRM for restoring patients' teeth. The handle may also include means disposed at its other end for retaining and displaying a label designating the particular TCRM, while the invention may also include a separate holder for retaining and displaying a plurality of handles with TCRM shade samples attached for easier color selection prior to selection and repair.
