摘要：
Oral appliance activation devices and methods which are used to facilitate the securement, adjustment, or removal of an oral appliance, e.g., a crown or bridge, from a reconfigurable abutment assembly are described. The adjustable abutment assembly may be secured to an anchoring implant bored into the bones within the mouth. The abutment assembly has a projecting abutment portion with one or more shape memory alloy elements extending along the projecting abutment portion. Energy may be applied to the elements via the activation devices directly over or adjacent to the oral appliance to actuate the elements and thereby either secure or loosen the oral appliance relative to the abutment.
