A partial dental arch is provided with dentin material and with cutting material and a boundary area therebetween. It includes a primary-position tooth region and additional tooth regions which are arranged more distally. A wavy structure of the boundary area is provided whose amplitude—when viewed in the distal direction—decreases in at least one section of the mesial-distal and/or occlusal-gingival extension, in particular with regard to the occlusal-gingival direction.

A three-dimensional device is fabricated in a layer-by-layer approach using a support material. The support material is deposited in a liquid form on a surface, hardened by cooling or ultraviolet (UV) curing, and selectively ablated to create an area within which the desired structure of the device will be formed. Active material is deposited into this area, and the layer-by-layer process repeated until the three-dimensional device has been completed. Thereafter, any remaining support material is removed by water or other solvent.

A dental milling machine includes a workpiece holder. The workpiece holder (10) has a bracket (11) and an adapter (12, 12′). The adapter (12, 12′) is mounted on the bracket (11). In a first state (17), the adapter (12, 12′) is a semimanufacture (16, 16′) and designed to be milled by the dental milling machine (1).

Provided herein are computer-implemented methods, computer-implemented systems, and a non-transitory computer-readable storage media for directing an automated dental drill (ADD) for preparation of a target tooth of a patient under the control of a practitioner

Translucency of a yttria-stabilized zirconia ceramic is improved to achieve even higher translucency than what is currently offered on the market, without greatly altering its mechanical properties. The enhancement is done by incorporating magnesium-containing dopants into the microstructure of yttria-stabilized zirconia ceramic dental ceramics.

A dental prosthesis is provided, manufactured from a one-piece or multi-piece prosthesis blank which is composed of a gum-colored material (14) and a tooth-colored material (14), especially each one being based on plastic material. The tooth-colored material (14) of the blank (10) has a diameter or a width of more than 5 cm and especially a substantially flat cylindrical shape with a diameter/height ratio of more than 2:1, preferably more than 3:1. The gum-colored and tooth-colored materials (14, 12) are bonded together by bonding, polymerization and/or integral production. The boundary (16) between the materials, as viewed in the direction of the dental arch course, is wave-shaped with alternating grooves and ribs (22, 24), and in the region of the anterior arch in the vestibular direction—is of radiant shape.

A method for making a ceramic body comprised of a ceramic material having an inhibitory effect on bacterial growth is provided. A dental prosthesis may be made of a ceramic material that comprises a molybdenum-containing component on a portion of the prosthesis that contacts the gingival surface of a patient. In one method, a porous zirconia ceramic structure is shaped in the form of a dental prosthesis, and then infiltrated with a molybdenum-containing composition, before sintering to densify the ceramic structure.

A method for manufacturing a dental restoration pre-form for use in a making a dental prosthesis is disclosed comprising providing a design of the prosthesis and a protocol for manufacturing the prosthesis and producing a dental restoration material pre-form having three dimensional (3D) characteristics based on said design of the prosthesis and steps of the protocol. There is also disclosed a method for manufacturing a dental prosthesis comprising providing dental restoration material pre-form having an associated 3D digital map, the 3D map comprising information on a spatial distribution of characteristics of the pre-form; and processing the pre-form according to a processing protocol the protocol based on a design of the prosthesis and the 3D map of the pre-form. Additionally, there is provided a system for manufacturing dental prosthesis comprising: a pre-form production unit, a pre-form processing unit, and a processor operationally coupled to the pre-form processing unit to execute a processing of the pre-form based on a selected processing protocol.

A method for making ceramic fixed partial dentures comprising separating the as-sintered partial denture structure, rejoining the retainers and pontic with glass, which forms a strong joint between the retainers and pontic after sintering. This method may produce ceramic long-span fixed partial dentures with a better fit.

A method and system are provided for manufacturing a physical dental model. A virtual model is provided representative of at least a portion of the intra-oral cavity including at least one dental implant implanted therein, and the virtual model includes a virtual portion representative of each dental implant. The virtual spatial disposition of each such virtual portion is determined with respect to the virtual model, corresponding to a real spatial disposition of the respective implant with respect to the intra oral cavity. A physical model is then manufactured based on the virtual model, the physical model including a physical analog corresponding to each implant at a respective physical spatial disposition with respect to the physical model corresponding to the respective virtual spatial disposition of the respective virtual portion with respect to the first virtual model as already determined. In some embodiments, a jig is provided configured for maintaining a desired physical spatial disposition between the physical analog and a cavity of the physical dental model at least until the physical analog is affixed in the cavity.
