  • Patent number: 9198502
    Abstract: A short wavelength visible light-emitting toothbrush with an electronic interlock control device preventing operation when the toothbrush is removed from the user's mouth. The electronic interlock control over operation is necessary to prevent accidental eye exposure to the high intensity light source with a wavelength in the range of 400 nm to 500 nm. The light-emitting toothbrush activates upon formation of an electrical circuit between the brush handle in contact with the users hand and the brush head or brush bristles in contact with moisture contained in a human mouth such as saliva or water mixed with toothpaste but deactivates immediately when removed from the mouth, thus protecting the user's eyes from direct exposure to the high power light source contained in the brush-head.

  • Publication number: 20150132714
    Abstract: The present invention discloses a tool, kit and method for applying loading, torsional/twisting, oscillatory or vibration induced forces to a bond line established between a tooth root surface and an associated bone defined socket within which the tooth is held. Forces are applied typically for a given number of cycles or iterations in order to adequately pre-loosen the tooth from the bone. In a most basic variant, a body is adapted to being engaged by an output portion of a force applying tool. The body includes a pair of tooth engaging portions adapted to being inserted into contact with opposite surfaces of the tooth root surface and opposing surfaces associated with the bone receiving socket. The tool introduces loading forces to the engaging portions, causing the tooth to displace within the socket sufficiently to fracture the bond with the bone, thereby facilitating tooth removal.

  • Publication number: 20150132712
    Abstract: Apparatus and methods for endodontic treatment of teeth provide effective cleaning of organic material (such as pulp and diseased tissue) from the root canal system. In an embodiment, a compressor system generates high pressure liquid (e.g., water) that flows through an orifice to produce a high-velocity collimated jet of liquid. The high-velocity jet is directed toward a surface of a tooth, for example, an exposed dentinal surface, and impingement of the jet onto the surface generates an acoustic wave that propagates throughout the tooth. The acoustic wave effectively detaches organic material from dentinal surfaces and tubules. The detached organic material is flushed from the root canal system by the liquid jet and/or by additional irrigation.

  • Publication number: 20150044634
    Abstract: In endodontic therapy, a probe tool is disclosed which enables the removal of a broken file or instrument fragment wedged in a root canal of a tooth. A shank portion of the probe tool is made at least in part from flexible planar sheet material such as stainless spring steel. In a preferred method of use, a dental handpiece transfers oscillations or other cyclical rapid motions through the inventive probe tool to the root canal wall at the juncture with the embedded fragment. A portion of the shank end of the probe tool may be coated with abrasive material. The rapid motions or oscillations imparted to the flexible probe abrade the area where the fragment is wedged and yet minimize collateral damage to adjacent dentinal surfaces. Other types of dental handpieces can be used to transfer vibrational, reciprocating, hammering or circulatory motion to the probe tool when necessary to enhance the effectiveness of the abrading process.

  • Publication number: 20120070799
    Abstract: An apparatus and a method for reducing pain and the discomfort experienced by a patient as a consequence of a needle stick during the administration of an injection. The pain-reducing apparatus includes a handle and a disposable fork detachably connected thereto. The fork has a pair of outstretched fingers that are separated from one another by a gap at which the injection site is located. Vibrations applied to the fork from the handle are transmitted from the fingers of the fork to the patient's tissue or skin surrounding the injection site. The vibrations desensitize the patient's tissue/skin during the administration of the injection.

  • Publication number: 20110300507
    Abstract: The invention relates to a coupling body that can convert a linear input movement into a linear output movement transversal to the input movement. The coupling body includes two parallel flexional arms of the same length, the ends of the flexional arms being connected by means of transversal connection arms. The connection arms carry driving bodies which represent load bodies arranged at the same distance from the neutral lines of the connection arms, in the same direction.

  • Patent number: 8046861
    Abstract: The toothbrush includes a handle portion and a brushhead assembly which comprises a head portion and a stem portion. The head portion includes a bellows-like acoustic action member for creating acoustic wave action as it moves in and out in response to an acoustic driving force. A drive system is located in the handle and includes an audio speaker-type assembly to create acoustic waves which are transmitted through a transmission line to the acoustic action member. The acoustic action member is driven toward and away from the teeth when the toothbrush is operatively positioned within the mouth. The action of the acoustic member is directly or indirectly coupled to the fluid in the mouth, producing a foam which couples shear forces between the acoustic action member and the teeth/gums to produce a desired cleaning/therapeutic effect.

  • Publication number: 20110165538
    Abstract: A non-contact apparatus and method detect irregular bone defects around a dental implant. Structural resonance frequency is produced and received to recognize a quality, a direction and a depth of an irregular bone defect. Thus, an interfacial osseointegration can be evaluated, and the present invention is of great help to assess osseointegration and diagnosis interfacial bone defects after the dental surgery.

  • Publication number: 20110065063
    Abstract: An improved low cost dental hygiene handpiece with high reliability coupling mechanism for disposable prophy angles and doriot type dental tool heads. The disposable prophy angles and dental tool heads are designed with non circular input shaft endings, engaging a matching non circular power output driver of the handpiece. The invention prevents the application of any axial force on the drive train and the driving motor both during the installation of the prophy angle and during the operation of the device, thereby eliminating the need for any axial trust bearings in the handpiece.

  • Publication number: 20100279252
    Abstract: According to one embodiment, an apparatus for removing enamel from a person's tooth includes a blade portion and a handle portion. The blade portion includes an abrasive surface adapted to remove enamel from the tooth in response to reciprocating movement of the abrasive surface against the enamel. The handle portion is coupled to the blade portion and includes first and second regions, the first region is proximal and the second region is distal to the blade portion. The first region includes a substantially solid cross-section with a substantially circular perimeter. The second region includes a substantially solid cross-section with at least a substantially semi-circular perimeter, the solid cross-section defining a notched region. The apparatus is adapted to be inserted via a pressure fit into a corresponding opening in a driver mechanism adapted to drive reciprocating movement of the blade portion and the abrasive surface.
