Abstract
A dental implant is provided for insertion into the jawbone of a patient for the purpose of building a dental prosthesis thereon. The implant includes a central hole having a wall with first extension for accommodating a dental post having a second extension that frictionally interlock with the first extension. A core can be provided which includes a second central hole having a wall with a third extension for accommodating a dental post having a fourth extension that frictionally interlocks with the third extension.
Claims26
A dental system for insertion into a bore of a jaw bone of a patient which comprises:
- a dental implant adapted to fit in a bore of said jaw bone, said dental implant having a central bore extending from a top surface of said implant through a portion of the vertical height of said implant,
- at least one first extension extending from and directly attached to a first wall of said central bore,
- a dental post having a stem section shaped to fit into said central bore and having a second wall with at least one second extension attached directly to said post and positioned to frictionally fit with said first extension to retain said dental post within said central bore.
The dental system of any one of claims 1, 2, 11, 18, 19, 3, 12, 20, 4 or 13 further comprising
- a core having a second central hole, extending from a bottom surface of said core through a portion of a vertical height of said core,
- at least one fourth extension extending from a wall of said second hole,
- and at least one fifth extension on said top section positioned to frictionally fit with said fourth extension to retain said top section within said second central hole.
A dental system for placing a core on a top section of a dental post inserted into an implant in the jaw of a patient which comprises:
- a core having a central hole, extending from a bottom surface of said core through a portion of a vertical height of said core,
- at least one first extension extending from and directly attached to a wall of said central hole, portions of said wall being tapered toward each other,
- and at least one second extension extending from and directly attached to said top section positioned to frictionally fit with said first extension to retain said top section within said central hole.
