Abstract: An integrated abutment block has an abutment with an internal portion imbedded in the block and a depending post.

Abstract: The position of intra-osseous implants and abutments to analogs is enabled and enhanced by using the longitudinal axial locked position of a post (12a) of an implant (12) having a locking taper in a bore (10a) of an implant (10) having a generally matching locking taper as a reference to determine the position of a stop surface (14c) on impression posts, abutment analog posts and the like received in the bore of an implant and implant analog. In another embodiment the bore (16) of an implant analog (16) is provided with a shelf (16c) located at a position determined by the axial distance of the locked position of the abutment post to prevent over-seating. Controlled retentive resistance and stability of a post is provided by using flats formed in the bore of an implant analog and by forming rings on a post receivable in the bore of an implant or implant analog.

Abstract: An abutment (10,10A,10B,10C) for a medical or dental implant has a prosthetic receiving tapered post formed with a locking step (10e) for removably restraining a sleeve member such as an emergence cuff (12,12A). The emergence cuff is receivable on the post of the abutment and has an outer surface configuration which merges confluently with the abutment outer surface. The emergence cuff is formed with a snap on interface (12g) for use with a second sleeve (14,14A) having a complimentary snap on interface (14e). When the second sleeve is open ended, a pin (16) is shown for closing off the outer end of the second sleeve, if desired.

Abstract: An integrated abutment crown (22) has an abutment portion (24) having a central portion (24a) intermediate to a post portion (24b) receivable in the bore of an implant and a head portion which includes a nose (24c) and shelf (24d) extending from the outer circumference of the central portion to the nose. The abutment portion (24) is formed with a smooth curved surfaces for supporting crown portion (26) material applied directly onto the nose and shelf of the head portion.
