Dental implant including plural anchoring means

Details

Inventors: Niznick, Gerald A.;
Assignee: Core-Vent Corporation (Encino, CA)
Primary Examiner: Mancene; Gene
Assistant Examiner: Lynch; Michael
Attorney, Agent or Firm:

A dental implant anchor includes a body portion having a first external wall portion carrying one or more circumferential projections separated by circumferential grooves and, below, a second external wall portion carrying threads. In some forms, the anchor also includes one or more longitudinally-oriented grooves on its exterior wall. The grooves extend across, and through the circumferential projections. The implant can include a head portion with a smooth external wall; a through-hole and an apical hole passing through the bottom of the implant; and internal structure for engaging a tool for inserting the implant in a passage formed in bone tissue. This internal structure can be in a top portion, or in an internal passage in the body portion of the implant. The method for forming a passage in bone tissue to receive the implant includes forming a passage having a base with a diameter suited to self-tapping of the threaded part of the implant, and, above the base, a larger-diameter section to engage frictionally the circumferential projections. A drill for forming such a passage in one step includes two such drilling portions that simultaneously form a two-diameter passage.

DETAILED DESCRIPTION What is claimed is: 1.
A substantially cylindrical dental implant anchoring means comprising a substantially cylindrical body portion adapted to fit in a passage formed in jawbone tissue, said body portion having an external wall portion carrying at least two circumferential or partially circumferential projections, each of said projections having a size and shape adapted to engage the walls of said passage substantially exclusively frictionally, each of said projections having a cross-section sufficiently large to engage frictionally the sidewalls of said passage, and to hold said anchoring means inside said passage immediately upon insertion of said dental implant anchoring means into said passage, each of said circumferential projections having a groove on each side of the projection to facilitate growth of bone tissue into said grooves to promote anchoring of said dental implant in said passage, and, below at least said two projections, an external wall portion carrying thread means adapted to screw into the end of said passage, said thread means having its axis at an oblique angle to the longitudinal axis of said substantially cylindrical dental implant; said anchoring means further comprising: at least two longitudinally-extending grooves passing through and interrupting each of said circumferential projections, each of said grooves being of sufficient depth and width to ensure bone growth into said grooves when said anchoring means is seated inside said passage.
2.
The dental implant anchoring means of claim 1 further comprising, above said body portion, a top portion having a smooth external wall, said top portion slanting outwardly and upwardly from a plane through said portion where said body portion joins said top portion.
3.
The dental implant anchoring means of claim 2 further comprising means internal to said implant for engaging means for inserting said implant in said passage.
4.
The dental implant anchoring means of claim 3 further comprising a through-hole passing laterally through said body portion near the bottom of said body portion
