Abstract
Official abstract text for this publication.
A green metal body includes metal particles and a binder in the shape of an orthodontic bracket and/or base plate. The green metal body is fabricated by being laser-cut with a laser to shape the green metal body into the shape of an orthodontic bracket and/or to carve recesses and/or undercuts into the bonding surface of the bracket. The green metal body is sintered to shrink its volume into a denser and less porous sintered metal body configured to be an orthodontic bracket. The resultant sintered orthodontic bracket includes recesses and/or undercuts in the bonding surface to provide a mechanical aspect when bonded to a tooth.
First claim
Opening claim text (preview).
What is claimed is: 1. A method of manufacturing an orthodontic appliance comprising: guiding a laser beam over a surface portion of a green body composed of particles held together by a binder in the shape of the orthodontic appliance to vaporize, melt, and/or decompose the binder at a point being hit by the laser beam; removing particles from the surface portion of the green body where the binder has been vaporized, melted, and/or decomposed to yield a laser-cut portion define…
