摘要：
Convertible orthodontic brackets (100) with a selectively removable labial web (112) are formed by machining. A circular pilot hole is formed so as to extend mesially-distally through the body of the orthodontic bracket (100). One or more shaping broaches are then pushed or pulled through the pilot hole so as to form a desired rectangularly-shaped arch wire hole (106) within the orthodontic bracket body (104). The area surrounding the labial web cover (112) is also machined to form first and second connecting web regions (114, 116) of reduced cross-sectional thickness on either side of the labial web cover (112). Manufacture by machining allows stronger more dense metals to be employed compared to manufacturing by metal injection molding.
