Abstract
A support post for use with a dental implant for supporting a prosthesis thereon is disclosed. The support post includes an implant-contacting region and a supragingival core section which extends from the trans-tissue region for supporting a prosthesis. An interface member is secured to the post at the bottom of the implant-contacting region for abutment between the implant-contacting region and an implant to which the post is to be secured. The interface member has material properties different from those from which the post is made and compatible with those of the implant. Typically the support post is made of ceramic material while the insert is made of titanium having hardness properties no greater than that of the implant with which it is used.
Claims21
A support post for use with a dental implant for supporting a prosthesis thereon, comprising:
- an implant-contacting region on the post and including interface means for abutment with an implant to which said post is to be secured,
- a supragingival core section extending from the implant-contacting region for supporting at least a prosthesis thereon, said interface means having material properties different from those from which said supragingival core section is made, and
- said supragingival core section is hollow with a passageway extending therethrough and said interface means comprises an insert which is press fit into said passageway at the bottom of said core section in a manner wherein said insert extends completely along the bottom surface of said support post to prevent contact between the support post and an implant with which it is to be used.
A support post to be secured to a dental implant for supporting a prosthesis thereon, comprising:
- an implant-contacting region on the post including a unitary interface means secured to the post for abutting with said implant;
- a supragingival core section extending from the implant-contacting region adapted to extend above a gingival surface of a dental patient for supporting at least a prosthesis thereon, said interface means having material properties different from those from which said supragingival core section is made and adapted to extend upwardly from said implant and terminate at a point within a transgingival region below said gingival surface;
- and
- said supragingival core section is hollow with a passageway extending therethrough and said interface means comprises an insert extending completely along the bottom surface of said support post to prevent contact between the support post and an implant with which it is to be used.
A support post to be secured to a dental implant for supporting a prosthesis thereon comprising:
- an implant-contacting region on the post interface means attached to the post for abutting with said implant, said support post being made of a material having a greater hardness than the implant with which it is to be used, said interface means being made of a material having a hardness no greater than that of the implant with which it is to be used;
- a supragingival core section extending from the implant-contacting region adapted to extend above a gingival surface of a dental patient for supporting at least a prosthesis thereon, said interface means having material properties different from those from which said supragingival core section is made and adapted to extend upwardly from said implant and terminate at a point within a transgingival region below said gingival surface;
- and
- said supragingival core section is hollow with a passageway extending therethrough and said interface means comprises an insert extending completely along the bottom surface of said support post to prevent contact between the support post and an implant with which it is to be used.
A support post to be secured to a dental implant for supporting a prosthesis thereon, comprising:
- an implant-contacting region on the post including interface means attached to the post for abutting with said implant, said interface means being opaque to x-rays and said support post being transparent to x-rays;
- a supragingival core section extending from the implant-contacting region adapted to extend above a gingival surface of a dental patient for supporting at least a prosthesis thereon, said interface means having material properties different from those from which said supragingival core section is made and adapted to extend upwardly from said implant and terminate at a point within a transgingival region below said gingival surface;
- and
- said supragingival core section is hollow with a passageway extending therethrough and said interface means comprises an insert extending completely along the bottom surface of said support post to prevent contact between the support post and an implant with which it is to be used.
