Abstract
An orthodontic bracket has tiewings with cavities for receiving an attachment, such as a hook or a ligating latch. Optionally, the bracket is made in two or more sections or bodies that preferably have cross-sectional configurations similar to each other when viewed in directions perpendicular to the archwire slot. When the bodies are assembled to each other, tiewing portions of each section are located adjacent each other to present a single tiewing.
Claims57
An orthodontic bracket comprising:
- a first body having a trunk portion, an occlusal tiewing portion, a gingival tiewing portion and an archwire slot portion extending between the occlusal tiewing portion and the gingival tiewing portion;
- and
- a second body having a trunk portion, an occlusal tiewing portion, a gingival tiewing portion and an archwire slot portion extending between the occlusal tiewing portion and the gingival tiewing portion,
- wherein the first body and the second body are located adjacent each other such that the occlusal tiewing portion of the first body and the occlusal tiewing portion of the second body present a single occlusal tiewing, and the gingival tiewing portion of the first body and the gingival tiewing portion of the second body present a single gingival tiewing.
