초록 ▼

A dental assembly for vertical attachment of an implant to a dental abutment for restorative dental procedures is disclosed. The implant includes a cylindrical body having an interior bore formed between a distal end and a proximal end. An abutment interface is formed on the proximal end of the cylindrical body. The interface includes a radial annular interior surface and a flat annular stop surface circumferentially bordering the interior bore. The assembly also includes an abutment including a stem and a post coupled to the stem. An interior bore is formed through the stem and the post. The abutment includes an interface section between the post and the stem. The interface section may include an annular radially curved exterior surface proximate to the post. The radially curved exterior surface and the circular flat surface interfaces with the abutment interface of the dental implant.

대표청구항 ▼

1. A dental implant system, comprising: an implant including: a cylindrical body having an interior bore formed between a distal end and a proximal end;an abutment interface on the proximal end of the cylindrical body, the interface including a flat annular stop surface circumferentially bordering the interior bore; andan anti-rotational cavity formed in the interior bore between the distal end and the abutment interface;an abutment including: a stem;a post opposite of the stem;an interior bore formed through the stem and the post;an interface section between the post and the stem for interfacing with the dental implant, the interface section having an annular radial exterior surface between the post and the stem, the annular exterior surface having a curved convex transition surface terminating into a circular flat surface, the stem extending from the circular flat surface, the circular flat surface contacting the flat annular stop surface of the dental implant, and the curved convex transition surface interfacing with an interior mating surface of the dental implant including a corresponding concave surface; andan annular groove having at least one vertical surface cut into the circular flat surface to allow compliant fit of the interface section with the abutment interface of the implant when the abutment is inserted in the implant; andan implant driver tool including a tip to hold the dental implant, wherein the interior bore includes a counter-bore between the distal end and the anti-rotational cavity, the counter-bore having a narrower diameter than the anti-rotational cavity and sufficient to accept the tip of the implant driver tool to hold the dental implant to the implant driver tool via frictional contact with the counter-bore. 2. The dental implant system of claim 1, wherein the abutment interface further includes a radial annular interior surface bordering the interior bore. 3. The dental implant system of claim 1 further comprising an external screw thread on the exterior of the cylindrical body. 4. The dental implant system of claim 1, wherein the interior bore includes a second cavity including internal screw threads to accept a screw attaching the implant to an abutment. 5. The dental implant system of claim 1, wherein the cavity has a polygonal interior wall. 6. The dental implant system of claim 5, wherein the interior wall of the cavity forms a double sided hexagonal socket for attachment to an abutment. 7. A dental restoration system comprising: an implant for attachment to a jaw bone of a patient, the implant including: a cylindrical body having an interior bore formed between a distal end and a proximal end;an abutment interface on the proximal end of the cylindrical body, the abutment interface including an interior concave interface surface and a flat annular stop surface circumferentially bordering the interior bore;an anti-rotational cavity formed in the interior bore between the distal end and the abutment interface; andan abutment including: a stem;a post opposite the stem;an interior bore formed through the stem and the post; andan implant interface section between the post and the stem, the implant interface section interfacing with the abutment interface of the dental implant, the implant interface section including an annular convex exterior surface between the post and the stem, and a circular flat surface, wherein the circular flat surface has a groove having a vertical wall extending into the implant interface section to provide compliant fit when the annular convex exterior surface contacts the interior concave interface surface of the abutment interface of the implant and the flat annular stop surface of the implant interface section contacts the flat circular stop surface of the abutment interface such that a first portion of the circular flat surface on an inner side of the circular groove and a second portion of the circular flat surface on an outer side of the circular groove are both contacting the flat annular stop of the implant when the abutment is inserted in the implant. 8. The dental restoration system of claim 7, wherein the abutment interface includes a radial annular interior surface circumferentially bordering the interior bore.
