Textured laser abutment for dental prosthesis bonding
The patent application (Publication Number: US20240024080A1) describes a method for manufacturing an abutment made of titanium or titanium alloy for dental implants. The abutment comprises a proximal section for implant attachment and a distal section for supporting a dental prosthesis. The distal section includes a textured receiving surface for bonding the prosthesis, with grooves forming a grid pattern. The texturing can be done by hollowing out grooves oriented obliquely at 45°, with the grid having a square pattern with sides between 150 µm and 350 µm. The grooves have a depth between 5 µm and 15 µm, and a laser can be used to yellow the surface before or after texturing.
Furthermore, the abutment includes rotation indexing members to prevent rotation with the prosthesis, with the face devoid of texturing. The patent also covers a dental restoration assembly comprising the abutment and a ceramic dental prosthesis with a connection surface for bonding to the abutment. The assembly can have a yellow-colored receiving surface and an inner housing in the prosthesis. The connection surface of the prosthesis does not undergo abrasive surface treatment, such as sandblasting, ensuring a secure bond with the abutment. Overall, the patent details a method for manufacturing abutments and dental restoration assemblies with specific texturing, coloring, and bonding features to enhance dental implant procedures.
