A compression tool for performing a finishing procedure, within a bore hole formed within a human jawbone so as to serve as an implantation site for a dental implant, by compression and densification processes, comprises a tapered body portion, and a plurality of flute sections disposed the body portion, wherein, when the compression tool is rotated in a clockwise direction and simultaneously axially inserted into the bore hole, the plurality of flute sections, which comprise structure for continuously cutting bone material from bone mass surrounding and defining the bore hole formed within the human jawbone, for accumulating the bone material so as to prevent the bone material from being evacuated from the implantation site, and for immediately compressing the bone material, cut from the bone mass surrounding and defining the bore hole formed within the human jawbone, back into the bone mass surrounding and defining the bore hole formed within the human jawbone will compress, compact, and enhance the density of the bone mass surrounding and defining the bore hole formed within the human jawbone.

A method of increasing movement of a tooth in a jaw having at least one tooth with an orthodontic brace thereon includes: (1) holding a handle of a device, the device having an elongate member extending from the handle and a screw tip at a distal end of the elongate member; (2) moving a sleeve along the elongate member to set a length of exposed screw tip; (3) locking the sleeve in place relative to the screw tip; (4) drilling a hole with the screw tip through a cortical bone of a jaw to increase movement of the tooth; and (5) stopping the drilling when the length of exposed screw tip has penetrated the jaw.

The invention relates to a method for producing a dental drill that has a shank (1) and a work section. The shank contains a centrally arranged, continuous first channel (3). The work section contains one or more continuous, spiral-shaped further channels (4a, 4b). The first channel and the further channels open into a common chamber (5) connecting the shank and the work section. The shank is sintered with the work section in order to form a one-piece, sintered component that encloses the chamber connecting the shank and the work section.

The present invention provides an ergonomic operational system and method thereof for a human operator such as a dental surgeon in image guided implantation. A physical or virtual display in close proximity to, or integrated with, the dental drill shows the information that demands a high frequency of observation from the surgeon. The surgeon is thus able to monitor the drilling site and the display at the same time, without moving his head toward other display not within his field of view. The invention exhibits numerous technical merits such as simplicity of operation, improved operational safety, higher productivity, and enhanced efficiency, among others.

A bone expander contains: a body including a limitation section formed on an upper end of the body, a drill tip formed on a lower end of the body and extending from a bottom of the limitation section, a defining shoulder formed in an expanding umbrella shape and between the bottom of the limitation section and the drill tip, and multiple spiral ribs formed on the drill tip and the limitation section. The drill tip has multiple chip delivery grooves, and a respective chip delivery groove is defined between the drill tip and a respective spiral rib. The limitation section has multiple guide flutes corresponding to the drill tip and extending from the multiple chip delivery grooves, the drill tip has a cutting portion extending from a distal end thereof, and the cutting portion has a conical face formed thereon.

In one embodiment, a dental bur includes a proximal shank, an intermediate cutting section, and a smooth, rounded distal tip. The cutting section includes (i) a frustum-shaped portion connected at its larger-diameter end to the shank and (ii) a curved portion that provides a transition between the smaller-diameter end of the frustum-shaped portion and the rounded tip, where the outer surfaces of the frustum-shaped portion and the curved portion are both sufficiently abrasive to remove bone tissue due to the presence of surface grit and/or flutes that provide bone-cutting edges. The dental bur reduces and flattens the bone tissue of the maxillary and mandibular bones for surgical dental implants without unwanted soft tissue damage.
