The invention relates to a method for constructing a restoration, in which a dental situation is measured by means of a dental camera and a 3D model of the dental situation is generated. In this case, a computer-assisted detection algorithm is applied to the 3D model of the dental situation, wherein a type of restoration and/or at least a tooth number and/or a position of the restoration to be inserted are automatically determined.

A system and method include digitally determining a virtual insertion path of a digital dental restoration.

Method and prosthetic system for producing a substitution bridge structure with prosthetic teeth (6), for replacing an existing bridge structure (2) which is mounted on a base structure (1), wherein the base structure (1) is fixed to implants (10) by means of base screws (11) and the head (15) of the base screws (11) has a screw hole. A scan body is fixed to the head (15) of the base screws (11) and an intraoral scan of the oral cavity is executed and the scan data is related to a 3D digital model of the base structure (1) and/or of the existing bridge structure (2), wherein subsequently a 3D digital model of said substitution bridge structure is designed.

A method of making an all-zirconium one-piece dental implant has: oral scanning after implantation of artificial tooth roots, 3D archiving, making temporary dentures, and making integrated permanent dentures. The oral scanning is executed by an optical scanner and generates a digital file of a denture model, a five-axis processing machine makes a temporary denture according to the digital file of the denture model to provide fitting information to modify the digital file of the denture model or make a permanent denture. Making the permanent denture with an all-zirconium material without metal support comprises the five-axis processing machine forming a through hole in the permanent denture.

The invention relates to a method for constructing at least one dental prosthetic part or a bracket, with at least one adhesive surface, in which a 3D model is made of the dental prosthetic part. Recesses are constructed on the adhesive surface of the 3D model.

A system and method include digitally determining a virtual insertion path of a digital dental restoration,

A method of producing a dental prosthesis produced from a gum part, and prosthetic teeth arranged on the gum part and connected to the gum part. The surface of the dental prosthesis is surface-treated, the surface treatment of the dental prosthesis involving a solvent, and the solvent containing at least one chlorohydrocarbon and at least one methane nitroderivative.

Dental preparation uses a tooth preparation guide custom-made liar fitting with teeth of a patient. The preparation guide includes one or more guide channels for guiding a cutting tool. The preparation guide enables modification of the teeth as planned with high level of precision. A dental prosthesis for installing onto prepared teeth of the patient is provided before preparation of the teeth. The prosthesis includes features that are complementary to the prepared teeth. The prosthesis can be installed immediately after preparing the teeth using the preparation guide. With the high level of accuracy and precision in the preparation of teeth, no modification of the prosthesis would be needed for installation.

Provided is a method for manufacturing a surgical guide, and a crown and an abutment in a mouth for a dental implant, including an operation of obtaining a primarily scanned image through scanning of inner and outer surfaces of a denture which has a first image matching groove matched with a patient's tooth implanting portion and in which a plurality of reference markers are attached to an outside, obtaining a secondarily scanned image through oral scanning of upper and lower jaws while the denture is installed, preliminarily matching the secondarily scanned image with the primarily scanned image, obtaining an integrated scanned image considering a vertical dimension by reversing the first image matching groove so that an image of the first image matching groove is dimensionalized from the primarily scanned image, and obtaining a CT image through CT scanning of the upper and lower jaws.

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.
