Abstract:
A near net shape medical device is described that is formed from a metal alloy mixture containing NiTiHf using additive manufacturing techniques. The medical device is aged to a desired ultimate tensile strength (UTS), presence of H-phase precipitate with an A f below body temperature.
Abstract:
An orthodontic device is disclosed comprising a head configured to be coupled to a tooth, the head having a first geometric configuration such that actuation of the head facilitates adjustment of the tooth, a neck adjacent the head to facilitate coupling of the head to the tooth, the neck having a second geometric configuration, the neck operable to transfer a force exerted on the head to the tooth and at least one of the neck and the head comprising a flexible material. In some embodiments, the orthodontic device further comprises a member operable to engage the head such that actuation of the head facilitates physical adjustment of the tooth and the member comprises an aligner and the aligner further comprises at least one well configured to engage the head.
