Laser etched sintered ceramic orthodontic brackets

Abstract

The present disclosure is drawn to laser etched, sintered ceramic orthodontic brackets. Such a bracket can comprise a working surface including an archwire slot and a ligating structure. The bracket can also include a laser etched tooth attachment surface that is laser etched after sintering of the ceramic orthodontic bracket. In another example, a method of increasing the average bonding strength of a sintered ceramic orthodontic bracket can comprise laser etching a tooth attachment surface of the sintered ceramic orthodontic bracket. In one specific example, the method can further comprise the preliminary steps of forming a ceramic material into a shape of an orthodontic bracket and sintering the orthodontic bracket.

Dependencies are inferred from the claim text.
