Bracket with bilayer base configured to produce a control value
DCFirst Claim
1. The combination of an orthodontic bracket and a laminated base for ready mounting of the bracket on a tooth, wherein the bracket includes an outwardly opening mesiodistally extending archwire slot and said base and/or its orientation with the bracket opening includes a built-in control value, said base comprising:
- a first layer of cured polymer resin of uneven thickness mesiodistally and integral with the bracket, anda second layer of uncured polymer resin of substantially the same family as the first layer defining a tacky surface for ready mounting of the bracket on a tooth, andsaid bracket and/or said cured first polymer resin layer of said base being configured to coact with the archwire slot to at least produce a rotation control value.

Abstract
A bilayer base for attaching appliances selected from the group consisting of a component of a dental appliance, an orthodontic appliance, or an orthopedic appliance to a bony part of the human body wherein the appliance part to be attached to the bony part of the body may be made of metal, ceramic, or plastic. The base permits the appliance to be ready for mounting and includes a cured layer of polymer resin mounted on the appliance and an uncured layer of substantially the same polymer resin over the cured layer which when cured becomes integral with the cured layer in attaching the appliance to a bony part of the body.

3. The combination of an orthodontic bracket and a laminated base for ready mounting of the bracket on a tooth, wherein the bracket includes an outwardly opening mesiodistally extending archwire slot and said base and/or its orientation with the bracket opening includes a built-in control value, said base comprising:
-
a first layer of cured polymer resin integral with the bracket, and a second layer of uncured polymer resin of substantially the same family as the first layer defining a tacky surface for ready mounting of the bracket on a tooth, and said bracket and/or said cured first polymer resin layer of said base being configured to coact with the archwire slot to at least produce a tip value wherein said cured first polymer resin layer is oriented on the bracket in non-alignment therewith to produce said tip control value.
