Abstract: A dental overlay device includes a base, connecting strut, and veneer holder. The base has a curvature in the form of an arch of a patient and defines a curved axis. The connecting strut has a first end attached to the base and a second end and extends in a generally orthogonal direction to the curved axis. The veneer holder has first and second ends and extends in a transverse direction to the direction the connecting strut extends. The second end of the connecting strut is attached to the veneer holder. A dental overlay device and veneer combination includes a first veneer and a second veneer prepared for mounting onto the plurality of teeth. Floss is configured for passing between the first veneer and the second veneer when the dental overlay device is mounted onto the plurality of teeth.

Abstract: A tooth preparation system (100) includes a dental tool (150) and guide device (110) for contacting the dental tool to limit its movement in removing predetermined tooth structure from a working tooth. The guide device includes a body (120) having an inner surface (146A), a channel (122A, 122B), an aperture (124, 126, 136), and an opening (127A, 127B). The inner surface is configured for attachment to a tooth to releasably fix the guide device. The channel extends partially through the body, defines a longitudinal axis, is configured for contacting a flange (152A, 152B, 154A, 154B) extending from a shaft of the dental tool to limit a movement of the tool, and defines a channel diameter perpendicular to a direction the longitudinal axis extends. The aperture extends through the body and is configured to expose the predetermined tooth structure. The opening extends between the channel and the aperture and has an opening diameter less than the channel diameter.

Abstract: Dental instrumentation for use in guiding a cutting tool to remove tooth structure from a working tooth is prepared. A digital model of cutting guide shell structure for placement around a portion of the tooth to be treated is combined with preset tool movements to be made by the cutting tool by one or more processors to define final cutting guide data corresponding to final cutting guide structure for guiding the cutting tool. A digital model of a fixation instrument configuration for fixing the dental instrumentation to an adjacent tooth to the working tooth is combined with the final cutting guide data by one or more processors to define final instrument configuration data corresponding to a final instrument configuration for releasably fixing the dental instrumentation to the adjacent tooth and for guiding the cutting tool in the removal of the tooth structure from the tooth to be treated.
