DR. NIZNICK'S DENTAL IMPLANT

Patents

Patent on implant with smooth neck and score lines for depth control

ABSTRACT:

Dental Implants include a threaded body portion having a textured surface, and an externally smooth neck portion having one or more depth gauge lines to guide insertion into a patient’s jawbone, with the neck portion projecting above the jawbone, allowing the gingival tissue to be sutured over the implant, or with the neck portion projecting through the gingival tissue.

Patent on Friction-fit Implant Extender with flat top to convert to MUA

ABSTRACT:

A screw-type dental implant assembly includes two parts: an endosseous dental implant with an internally-threaded shaft and an internal wrench-engaging surface, located inside the body of the implant, for inserting the implant into a patient’s jawbone; and a separate extender/post/abutment (the “extender”) for frictional insertion into, and for attachment to the implant’s internal shaft, that includes a flat top surface with a diameter of about 4mm to 6mm in diameter, where the flat top has a circular profile.

NizPlant™ 1-Piece Locator® Compatible Implant with Internal Threads

Only in 3.2mm Diameter and 1 Collar Height with All-in-1 Packaging for $125

ABSTRACT:

A screw-type endosseous dental implant includes, near the top on the implant’s external surface, a ridge projecting laterally, and an internally-threaded shaft with a lead-in, beveled opening, an internal wrench-engaging surface located below said lead-in, beveled opening, and, below said internal wrench-engaging surface and above said internal threads, an internal undercut/groove forming a chamber configured to receive a snap attachment for retention of an over-denture.

1986 Screw-Vent Implant:

ABSTRACT:

Dr. Niznick introduced the Screw-Vent® dental implant in grade 1 commercially pure titanium. The Screw-Vent incorporated the same thread design and diameter (3.75 mm) as the Brånemark implant, but featured a 1.5 mm-deep internal hexagon with a threaded shaft below it. This patented connection provides the stability needed between the implant and the abutment to prevent screw loosening and thus minimizes long-term prosthetic complications. It also allows screw-retained, two-piece abutments to interlock with the internal hexagon to prevent rotation, which made single tooth replacement a viable option in implant restorations. At the top of the internal hexagon, a lead-in bevel helps stabilize the abutment against lateral forces and reduces the chance of tissue being trapped in the joint, which could result in incomplete seating.
