Abstract
Aspects of the present invention include a screw device configured for implantation into human bone for dental and bone restoration purposes, or animal long bone. More particularly, embodiments of the present invention include a surgical screw having a surgical pinpoint tip, a head, a set of threads having a dynamic surgical region including quantified progressing minor diameters and a stabilizing surgical region including a substantially equal and parallel minor diameter between threads, and in some embodiments, an annular region and/or a tapered region. The set of threads are surgically sharp at the crest. The combination of these features enables the screw to be implanted without use of a drill or osteotome and without breaking.
Claims20
A surgical screw, comprising:
- a shaft having a dynamic surgical region and a stabilizing surgical region;
- the shaft comprising a set of threads disposed thereon,
- wherein the set of threads extends from a pinpoint surgical cutting tip at a first end of the shaft through the dynamic surgical region and to the stabilizing surgical region;
- wherein the set of threads comprises a first set of minor diameters extending through the dynamic surgical region, the first set of minor diameters comprising four progressively increasing parallel minor diameters from the pinpoint surgical tip toward an interface of the dynamic surgical region with the stabilizing surgical region, and
- wherein the set of threads comprises a plurality of minor diameters of equal size extending from the interface toward a second end of the screw shaft.
A screw device comprising:
- a thread having a first set of minor diameters and a second set of minor diameters,
- wherein the first set of minor diameters comprises four progressively increasing parallel minor diameters, and
- wherein the second set of minor diameters comprises a plurality of minor diameters of equal size dimensions;
- wherein the first set of minor diameters are substantially parallel to one another;
- and
- wherein the first set of minor diameters comprises:
- a first minor diameter of approximately 0.25 mm;
- a second minor diameter of approximately 0.43 mm;
- a third minor diameter of approximately 0.79 mm;
- and
- a fourth minor diameter of 1.12 mm.
A method of installing a screw device into bone of a patient without first drilling holes comprising:
- preparing an implant site for insertion of the screw device;
- providing a screw device, the screw device comprising:
- a first set of minor diameters and a second set of minor diameters,
- wherein the first set of minor diameters comprises four progressively increasing parallel minor diameters, and
- wherein the second set of minor diameters comprising a plurality of minor diameters of equal size;
- aligning pinpoint tip of the screw device with a position on a bone at the implant site;
- and
- pushing the screw into the bone.
