DENTAL IMPLANT ADAPTOR

摘要

One aspect of the invention concerns a dental implant adaptor (10) which is particularly suitable for dental crown implantation using a screw-retained protocol. The adaptor has a hollow body (12) that can be mounted on a dental implant (50). The body includes a crown-receiving portion (14) on which a dental crown (60) can be mounted. The portion (14) has a distal end and a proximal end and includes a first anti-rotation formation (28, 30, 34, 90) to prevent rotation between the adaptor and the crown. The body also has a laterally projecting collar (20) at the proximal end of the crown- receiving portion which, in use, locates on the implant. There is also a second anti-rotation formation (38) shaped for non-rotational engagement with the implant. The crown-receiving portion and collar together have an overall axial length in the range 3.5mm to 7mm and the collar has an axial thickness of 1.5mm or less. Another aspect of the invention is concerned with an implant assembly incorporating the adaptor
