Abstract: Dental implant systems, components and methods feature use of a mounting component onto which an abutment is to be cast or soldered. The mounting component is configured with an upper end that is contoured in a spherical or other suitable manner to present a surface over which the abutment can be slid into various positions on said surface at various angles relative to an axis of the implant body on which the mounting component is supported. Accordingly, the abutment can be set at a desired angle whether the this desired orientation matches or misaligns with the axis of the implant body.

Abstract: An orthodontic alignment device can have a palatal contour anchorage (PCA) feature that generally matches the shape of the patient's hard pallet. This PCA feature may be built slightly off-set to deliberately push against the patient's palate and/or gingiva to provide anchorage support of staged translation of the teeth. By transferring the required anchorage away from the teeth and onto the palate, through the PCA feature, the adjacent teeth are no longer subjected to unwanted side effects of reaction forces.
