receiving a plurality of guide projections of a dental instrument through respective side apertures in a first direction, each of the side apertures being defined by and extending between ends of adjacent guide walls of a plurality of sets of adjacent guide walls of a first dental overlay device mounted on either one or both of the working tooth or another tooth in the patient's mouth;
receiving a tooth treatment element of the dental instrument defining a longitudinal axis through a side opening in the first direction, the first direction being transverse to the longitudinal axis of the tooth treatment element, the tooth treatment element being configured for removal of tooth structure and the side opening being defined by and extending between ends of one of the adjacent guide walls of each of the sets of adjacent guide walls; and
moving the tooth treatment element towards the working tooth while maintaining the plurality of guide projections between the sets of adjacent guide walls, the first dental overlay device being configured to contact the plurality of guide projections of the dental instrument to limit the movement of the tooth treatment element and thereby restrict the portion of the working tooth structure to be removed from the working tooth to the predetermined portion of working tooth structure.
