(i) a base having one or more surfaces for contacting portions of one or more teeth in a patient to secure the overlay device in a suitable position with respect to the tooth to be treated, and the base further having one or more open areas for exposing the portion of the working tooth structure to be removed; and
(ii) a cutting guide comprising a plurality of sets of adjacent guide walls attached to the base, ends of the adjacent guide walls of each of the sets of adjacent guide walls defining a respective side aperture configured for receipt of a guide projection of separated guide projections of the dental instrument in a direction transverse to a longitudinal axis defined by a respective one of the separated guide projections, a combination of an end of one of the adjacent guide walls of each of the sets of adjacent guide walls defining a side opening for receipt of the tooth treatment element between the guide walls of the combination, wherein each of the adjacent guide walls of each of the sets of adjacent guide walls have a predetermined configuration for contacting the respective one of the guide projections of the separated guide projections of the dental instrument to limit the movement of the tooth treatment element of the dental instrument and thereby restrict the portion of the working tooth structure to be removed to the predetermined portion of the working tooth to be treated.
