A method for directly printing orthodontic and dental appliances on the teeth of a patient. The tooth is scanned with a scanner which is communicated with a computer controller configured to recognize the anatomy of the tooth. The surface of a tooth of the patient is then prepared in order to receive the type of appliance designated for the patient. Using image data from the print head, the computer controller prepares a three-dimensional blueprint or design of an appropriate orthodontic or dental appliance. The computer controller controls the type and amount of material that is distributed through the print head only when the print head passes over the recognized anatomy so as to directly print the corresponding appliance onto the tooth layer by layer as the print head makes successive passes over the surface of the tooth.

A dental crown and method of use thereof. According to the method provided herein, a dental crown is selected having an appropriate size and shape and an internal contour. The tooth to which the crown is to be applied is prepared to have an external contour. Composite material is injected into the internal contour of the dental crown. The dental crown is placed over the prepared tooth and the deposited composite material is cured using light.

A crown handling device is provided to allow an operator to hold the crown between fingers. The crown handling device comprises a matrix member; and a pinch holding member having a substantially round shape and a plurality of openings for inserting therethrough the matrix member secured to one side of the pinch holding member.

In the case of a dental prosthesis comprising a gum-coloured prosthesis base and a tooth coloured tooth arrangement which is partially embedded into the prosthesis base, the dental prosthesis is formed as a hybrid prosthesis, wherein the prosthesis base has a contact surface which has a surface normal pointing towards the gums.

The tooth arrangement (14) surrounds an external telescope (secondary part) or an abutment on at least 2 sides (26, 28, 30), is formed as a one-piece tooth quadrant or as a segmented tooth quadrant (16) and consists of a harder material than the prosthesis base (12).

Described is a customized removable cosmetic or aesthetic dental veneer that secures onto a row of teeth of a patient. The dental veneer may include a pair of rear portions that secure it onto the row of teeth, each rear portion positioned at a distal end of the veneer and having: buccal, occlusal and lingual sides for one or more rear tooth, and a front portion between the pair of rear portions that covers the buccal and occlusal surfaces of the teeth between the pair of rear portions but is free of a side that covers a majority of the lingual surface of any tooth of the row of teeth between the pair of rear portions. A slot and apertures may also be provided for occlusal portions of the rear teeth. Also described is a veneer without such rear portions, which may be used with an adhesive.
