摘要：
A dental implant adaptor which is particularly suitable for dental crown implantation using a screw-retained protocol has a hollow body that can be mounted on a dental implant. The body includes a crown-receiving portion on which a dental crown can be mounted. The portion has a distal end and a proximal end and includes a first anti-rotation formation to prevent rotation between the adaptor and the crown. The body also has a laterally projecting collar at the proximal end of the crown-receiving portion which, in use, locates on the implant. There is also a second anti-rotation formation shaped for non-rotational engagement with the implant. The crown-receiving portion and collar together have an overall axial length in the range 3.5 mm to 7 mm and the collar has an axial thickness of 1.5 mm or less. Another described is an implant assembly incorporating the adaptor.
