Abstract
A dental implant for supporting a dental prosthesis comprises a body portion and a top surface. The implant further comprises an internal cavity with an opening located at the top surface. The internal cavity comprises an interlock chamber having a depth measured from the top surface equal to a first distance. The interlock chamber comprising a cylindrical portion and plurality of semi-circular channels arranged around a periphery of the cylindrical portion. A threaded chamber that includes threads is located below the post-receiving chamber. The cylindrical portion has a first radius and the channels have a second radius, a ratio of the first radius to the second radius being between approximately 4:1 and 2:1.

A dental implant for supporting a dental prosthesis, the dental implant comprising a body portion and a top surface, the implant further comprising an internal cavity with an opening located at the top surface, the internal cavity comprising an interlock chamber having a depth measured from the top surface equal to a first distance, the interlock chamber comprising a cylindrical portion and plurality of semi-circular channels arranged around a periphery of the cylindrical portion, and a threaded chamber that includes threads and is located below the post-receiving chamber, wherein the cylindrical portion has a first radius and the channels have a second radius, a ratio of the first radius to the second radius being between approximately 4:1 and 2:1.
A prosthodontic assembly for installing a prosthetic tooth, the prosthodontic assembly comprising:
- a first prosthodontic component comprising a body portion and a top surface, the first prosthodontic component further comprising an internal cavity with an opening located at the top surface, the internal cavity comprising an interlock chamber having a depth measured from the top surface equal to a first distance, the interlock chamber comprising a cylindrical portion with a plurality of semi-circular channels arranged around a perimeter of the cylindrical portion, and a threaded chamber that includes threads and is located below the interlock chamber, wherein the cylindrical portion has a first radius and the channels have a second radius, a ratio of the first radius to the second radius being between approximately 4:1 and 2:1,
- a second prothodontic component comprising an interlock area comprising a plurality of semi-circular protrusions configured to mate with channels of the first prosthodontic component.
A dental implant for supporting a dental prosthesis, the dental implant comprising a body portion and a top surface, the implant further comprising an internal cavity with an opening located at the top surface, the internal cavity comprising an interlock chamber having a depth measured from the top surface equal to a first distance, and a threaded chamber that includes threads and is located below the post-receiving chamber, the interlock channel being formed as a single continuous curve having substantially no internal corners.
A prosthodontic assembly for installing a prosthetic tooth, the prosthodontic assembly comprising:
- a first prosthodontic component comprising a body portion and a top surface, the first prosthodontic component further comprising an internal cavity with an opening located at the top surface, the internal cavity comprising an interlock chamber having a depth measured from the top surface equal to a first distance, the interlock chamber being formed as a single continuous curve having substantially no internal corners, and a threaded chamber that includes threads and is located below the post-receiving chamber,
- a second prothodontic component comprising an interlock area a having a shape that corresponds to the shape of the interlock chamber.
