Abstract
A universal dental implant arrangement includes both internal attachment and external attachment possibilities. This is achieved by utilizing an anchor having an internal void or abutment receiving bore, adapted for internal attachment-type abutments, along with a platform that can be used for various purposes. The universality of the implant is in providing the alternative of leaving the platform in place, causing the implant to function as an external attachment implant, or removing the platform and thereby converting the implant into an internal attachment implant. The platform can support an external attachment abutment or be remove so that the implant can accommodate an internal attachment abutment.
Claims49
A universal dental implant arrangement for attaching at least one replacement tooth to the jaw bone of a mammal and that is capable of being used in both internal and external attachment applications, the arrangement comprising:
- an anchor for implantation into a hole in the jaw bone, the anchor having a lower portion with an outer surface, the anchor having an upper portion with an upper surface and an abutment receiving bore extending into the anchor and opening at the upper surface;
- a platform attached onto the upper surface of the anchor;
- a non-circular projection fixed to a top surface of the platform;
- orientation means defined between the anchor and the platform for establishing a plurality of relative rotational positions of the platform on the anchor when the platform is engaged to the anchor;
- and
- an abutment adapted to support a tooth replacement, the abutment having a foundation extending into and fixed to the abutment receiving bore in the anchor when the tooth replacement is to be supported on the anchor.
A dental implant arrangement for attaching at least one replacement tooth to the jaw bone of a mammal, the arrangement comprising:
- an anchor for implantation into a hole in the jaw bone, the anchor having a lower portion with an outer tapered surface and a thread on the outer tapered surface, the anchor having an upper portion with an upper surface and an abutment receiving bore extending into the anchor and opening at the upper surface;
- a rotation body engaged onto the upper surface of the anchor for rotating the anchor in the jaw bone hole;
- a non-circular projection fixed to a top surface of the rotation body and having at least one external wrench-engaging surface adapted for engagement by a wrench for rotating the rotation body;
- co-rotation means defined between the anchor and the rotation body for transmitting rotation of the rotation body to the anchor when the rotation body is engaged to the anchor and is rotated;
- and
- an abutment adapted to support a tooth replacement, the abutment having a foundation extending into and fixed to the abutment receiving bore in the anchor when the tooth replacement is to be supported on the anchor.
