The present disclosure is directed to tools, systems and methods for recontouring/reshaping gum tissue by engaging a consumable tip on a dental hand tool to abrade/ablate excess or mal-contoured gum tissue to allow better visualization of the tooth/implant structure and reduce the periodontal pockets to provide improved access for cleaning. In some embodiments, the dental hand tool may use vibrational movement, longitudinal reciprocating movement, rotational movement, reciprocating rotational movement, or a combination of any of the above movement schemes. In some embodiments, a consumable tip may be directed for cleaning tooth/implant surfaces and for recontouring/reshaping gum tissue.

An example embodiment of a dental tool includes a main body portion having a first longitudinal end and a second longitudinal end, wherein the first end and the second end define respective reduced diameter portions, two or more tool attachments, each tool attachment comprising a working portion and a base portion, the base portion configured to be removably coupled to either of the reduced-diameter portions of the main body portion so as to secure the tool attachment to the main body portion, and a light source, disposed within the main body portion, arranged so as to illuminate the working portion of one of the tool attachments when the one of the tool attachments is coupled to the first end of the main body portion and the light source is electrically coupled to a power source.

Motion-assisted dental treatment method and apparatus. Manual back-and-forth manipulation of a handpiece with respect to a working surface automatically reciprocates a tip with respect to the handpiece in phase with the operator manipulation to amplify the movement of the tip adjacent the working surface and thereby attenuate the extent of hand motion required, which can help to alleviate repetitive motion fatigue. Also disclosed are motion-assisted dental treatment tools and systems for implementing the method.

Dental hygiene and periodontal hand instrumentation requires alignment of the cutting surface of the instrument at a specific angle and adaptation to the tooth surface. A dental hygiene and periodontal hand instrumentation tutor provides an objective, consistent and accurate way to measure and display the actual angulation and adaptation angles of a periodontal hand instrument and assess instrument use continuously. The method includes detecting the position, orientation, motion path, pressure, angulation angle, adaptation angle, and centerline angle of a periodontal hand instrument and comparing them to ideal positions, orientations, and motion paths; and provides various forms of user feedback.

Dental handpieces, motors, couplers and other dental instruments and methods having multiple very small, high output, LEDs in a single lamp assembly to facilitate incorporation of a plurality of wavelengths emitted from these devices to allow dentists to select between the benefits of multiple wavelength light outputs to the working area in a single device.

An insert assembly has an insert having an insert metal tang, and a radiofrequency identifier having a ferromagnetic layer in contact with the insert metal tang and including ferromagnetic material, a dielectric layer in contact with the ferromagnetic layer, an insert antenna in contact with the dielectric layer and having an insert antenna metal element extending along a planar profile for receiving and transmitting electromagnetic fields, and an identification chip operatively connected to the insert antenna for transmitting and receiving information about the insert assembly. The ferromagnetic layer reduces or cancels attenuation and/or distortion phenomena of electromagnetic fields. A transceiver device puts the identification chip in wireless communication with a handpiece antenna. The identification chip avoids protruding from a first or outer side of the planar profile. A part of the identification chip protrudes with a chip portion from a second or inner side of the insert antenna metal element. The chip portion is received in a chip seat.
