Title: Dental implant component

Abstract: A set of dental implant components for use in fabricating a dental prosthesis (25) comprising a support component (19) for inclusion in a model of a jaw having a support end (17) and a socket (21); a sleeve cylinder (15) on which the dental prosthesis or a core part of the dental prosthesis is to be fabricated, the sleeve cylinder having a distal end adapted to engage with the support end of the support component, a proximal end and a channel extending from a distal opening in the distal end to a proximal opening in the proximal end; and an access passage-forming post (1) having a distal section (9) which presents a distal end (11) of the post and a proximal section (7) which presents a proximal end (3) of the post, the post being adapted to be disposed in an operational position when the distal end of the sleeve cylinder engages with the support end of the support component in which the distal section (9) of the post is releasably secured in the socket in the support component through the proximal opening of the channel in the sleeve cylinder and in which the proximal section (7) of the post protrudes from the proximal opening of the channel in the sleeve cylinder. The distal section of the access-passage forming post is releasably securable in the socket in the support component by a biasing force which biases the distal section and an inner surface of the socket together.
