Abstract: Pure compressed diamond (PCD), grown in a laboratory, is laser-shaped into dental implants with high tensile strength, high compressive strength, high thermal conductivity, and which are harder than any other substance on earth. PCD is harder than ceramic zirconia and harder than titanium. Because PCD is pure carbon, it is also 100% compatible with carbon-based living tissue. Unlike titanium, it does not provoke an immune response. PCD implants readily integrate into human jawbone. This drastically reduces post-surgery bone loss.

Abstract: An orthodontic self-ligating bracket for orthodontic treatment of maloccluded teeth is provided that includes a bracket body and a bracket door including a coplanar spring. The bracket body has a base that is contoured to attach to a surface of a tooth, a archwire slot on the top side of the bracket body extending in a mesiodistal direction and configured to releasably retain an archwire, and a bracket groove on the top side of the bracket body extending in an occlusogingival direction towards the archwire slot. The coplanar spring includes a spring body and one or more legs that deflect in direction generally coplanar with a plane of motion of the bracket door. The one or more legs interact with one or more depressions in the bracket body to move and retain the bracket door on the bracket body.

Abstract: An orthodontic positioning device including a patient removable orthodontic tooth positioning appliance having teeth receiving cavities shaped to receive and apply a resilient positioning force to a patient's teeth provided in one of an upper jaw and a lower jaw and comprising a cutout operable to expose an orthodontic elastic band receiving member.

Abstract: The present disclosure is directed, at least in part, to a self-ligating orthodontic bracket system that includes a rotatable member for securing an archwire within a slot of a bracket. Embodiments of the orthodontic bracket system disclosed herein include a bracket body containing the archwire slot as well as tie wings for attaching various orthodontic devices (e.g., elastomeric bands) to the bracket. The rotatable member is rotatable in a first direction (e.g., counter clockwise) relative to a body of the bracket for securing or locking the archwire within the slot, and for rotating in an opposite direction (e.g., a clockwise direction) relative to the bracket body for unsecuring or unlocking the archwire so that it is substantially unrestrained from exiting the slot.

Abstract: A set of primer appliances and a set of treatment appliances to be worn by a subject are provided. The primer appliances are first worn to prepare the local environment of the teeth for further repositioning of the teeth by the treatment appliances. The primer appliances may apply compression to the periodontal ligament, in a direction favorable for achieving the desired final position of a tooth. The compression may generate a biological response in the local environment of the teeth. The primer appliances may cause minimal or no repositioning of the teeth. The treatment appliances are worn to reposition the teeth from an initial position to an end position of a treatment stage. The primer appliances can improve the efficiency and accuracy of tooth movement by the treatment appliances.
