Total Claims: 13
Claim 1
Independent Claim
89 words
An orthodontic bracket comprising: a substantially non-resilient bracket member having a base and an arch wire receiving opening formed in a surface of said bracket; and a generally ring-shaped mounting layer of resilient material secured to said base of said bracket member and adapted to be mounted to a tooth or the like, said mounting layer having peripheral edges which extend at least adjacent to the periphery of said base of said bracket and a void space interior of said peripheral edges which underlies said base of said bracket.
Claim 2
Dependent Claim
89 words
An orthodontic bracket comprising: a substantially non-resilient bracket member having a base and an arch wire receiving opening formed in a surface of said bracket; and a generally ring-shaped mounting layer of resilient material secured to said base of said bracket member and adapted to be mounted to a tooth or the like, said mounting layer having peripheral edges which extend at least adjacent to the periphery of said base of said bracket and a void space interior of said peripheral edges which underlies said base of said bracket.
