The disclosure relates to rotary instrument indication systems. Also disclosed herein are rotary tools including indication systems. The indication systems can include a pressure sensor that can monitor force or pressured applied through a rotary instrument. A pressure indicator can also provide a feedback indication when the monitored force or pressure reaches or exceeds a predefined threshold. In some aspects, the rotary instrument is a dental drill.

A dental implement is disclosed that includes a proximal end portion; a distal end portion that includes a cutting head defining at least one cutting surface; and a guide body that is positioned proximally of the cutting head. The guide body defines at least one flute that extends in generally parallel relation to a longitudinal axis of the dental implement and is configured to direct irrigation fluid to a surgical site within a patient.

Apparatus and method for installing a multi-tooth dental prosthesis in one session are shown and described. A first tool attaches to the jawbone, and serves as a foundation for subsequently used guides. Existing teeth and dental fixtures are removed, and the bone tissue is removed to accommodate the prosthesis. Subsequently, a drill guide is used to drill implant holes. An abutment guide is then used to place abutments. Copings are then installed. Next, the prosthesis may be installed and cemented to the copings. A resinous filler material may be applied to fill gaps and holes in and between the copings and the prosthesis, and is sanded smooth.

A dental bur for removing precise portions of a tooth includes a shank and a head. The shank includes first and second end, an attachment section located adjacent the first end, and a guide section located between the attachment section and the second end. The attachment section is configured to be inserted into and rotationally driven by a high-speed rotary device. The guide section includes at least one portion having a first width measured in a transverse direction of the shank and a second portion having a second width measured in the transverse direction. The first width being different than the second width. The head is arranged on the second end of the shank and includes a tip located opposite the shank. The tip has a rounded portion configured to remove portions of the tooth, and the head is entirely coated in an abrasive diamond material.

A dental instrument comprising a shaft and a working part adjoined thereto, with the working part having a coating in which abrasive bodies are embedded, is proposed. Firstly, the average proportion of the surface of the abrasive bodies which is covered by the coating can be at least 60%, preferably at least 65%, most preferably at least 70%. Secondly, the coating can, moreover, also consist of a nickel alloy which additionally contains at least one element selected from the group consisting of titanium, vanadium, niobium, chromium, molybdenum, tungsten, manganese, iron and cobalt. In addition, a process for coating a working part, in particular for producing a dental instrument of this type, and also the use of such a dental instrument for cutting machining of solid bodies are proposed.

Endodontic instruments are described which have at least a section with a center of mass offset from an axis of rotation so that when the instrument is rotated, the section bends away from the axis of rotation.
