Dental prosthesis molding block and method for producing a dental prosthesis part from the dental prosthesis molding block

Dental prosthesis molding block for producing a dental prosthesis part, comprising:

• an opening;
• an inner material with a second region of the opening disposed within the inner material;
• and
• an outer material with a first region of the opening disposed within the outer material;
• wherein the inner material comprises an extension into the outer material such that the extension and the second region are at least physically and partially surrounded by the outer material and an end surface of the inner material proximal to a second surface of the dental prosthesis molding block is embedded in the outer material,
• wherein the hardness of the outer material differs from the hardness of the inner material,
• wherein the inner material forms a part of a first surface of the dental prosthesis molding block that also includes the outer material, the first surface being opposite to the second surface,
• wherein the opening comprises an internal screw thread disposed in the inner material, the opening extending from the second surface, through the outer material and into the inner material,
• wherein the second surface does not include the inner material,
• wherein the first region of the opening comprises smooth inner walls,
• wherein the second region of the opening comprises the internal screw thread, and
• wherein the dental prosthesis part is an implant.
