  • Patent number: 9055989
    Abstract: The invention is a low-splash dental fluid distribution implement with the ability to evenly wear down tooth decay, diseased tissue, or undesired dentin in oral applications with live patients. The directed multi-beams of pressurized fluid are a combined plurality of individual beams paired in such a manner that the reflected fluid bursts are inwardly directed against each other. This canceling effect prevents damage to the oral tissues of the patient's mouth by curtailing outward bound bursts of fluid arising from the initial directed impact. Also, the outer edges of the strike zone receive a comparable force as that which hits the center.

    Abstract: The present invention is in the field of tooth cleaning devices, especially electrical toothbrushes. The invention further relates to the use of an air/water jet for the cleaning of teeth. A process for cleaning teeth that incorporates a water jet for cleaning teeth remains to be desired, especially a single device that can be employed to clean teeth and reliably deposit material onto teeth. It is therefore an object of the present invention to provide a process for cleaning teeth with an electrical toothbrush device providing improved cleaning by means of an externally mixed air-water jet wherein the water dosing is not influenced by the air pressure. Surprisingly it has been found that a tooth brush device, comprising an air/water jet, wherein the air and water are mixed outside the nozzle(s), provides improved cleaning of dental surfaces, including inter-proximal areas, with low usage of water.

  • Publication number: 20140127640
    Abstract: A dental drill is disclosed which allows for an osteotomy to be formed in a shape which closely matches the cylindrical shape of many dental implants. In so doing, the implant engages more tissue of the resulting osteotomy, thus resulting in greater ability for the tissue to penetrate and fuse with the implant while also reducing the chances of infection and reducing the overall recovery time. In addition, by forming the dental drill with a relatively obtuse angulation between the termini of the drill flutes, the cutting forces are spread across a larger cutting area thus reducing wear on the drill itself. Moreover, by spreading the cutting force over a larger area, the heat generated by the drill is reduced and thus the discomfort afforded to the patient is reduced.

    Abstract: A dental bur and method for removing a soft deposit from a tooth or an implant, the bur having a shank adapted to be connected to a rotary device. A head extends from the shank. The head has a material hardness adapted to remove soft deposits attached to the tooth but deflect against the tooth. Furthermore, the head is sized for insertion into a periodontal pocket adjacent to the tooth without surgery. Thus, the dental bur may be rotated against the tooth for removing the soft deposits but deflect and/or wear against the tooth for preventing damage to the tooth.

  • Publication number: 20140106295
    Abstract: A system for reconditioning a dental implant in situ comprising a buffer member, a drive member, abrasive material, and a sleeve member. The sleeve member moves between first and second positions relative to the buffer member. The buffer member is in an open configuration when the sleeve member is in the first position. The sleeve member holds the buffer member in a closed configuration when the sleeve member is in the second position. The buffer member is rotated such that the plurality of fingers of the buffer member cause the abrasive material to remove at least a portion of the texture layer on the textured portion of implant outer surface of the second implant portion.

  • Publication number: 20140093836
    Abstract: An oral hygiene system for cleaning teeth and gums includes a mouthpiece having at least one arcuate channel adapted to receive and surround the teeth. The mouthpiece includes at least two modalities chosen from a group consisting of a mechanical modality, an iontophoretic modality, and a disinfection modality, wherein the mechanical modality brushes the teeth and gums and dislodges food debris, the iontophoretic modality breaks up plaque and tartar buildup, and the disinfection modality removes the food debris, plaque and tartar buildup. A control system coordinates the transmission of modalities, tracks and records utilization, recording completed and failed treatment cycles, and transmits them to a monitoring system. The monitoring system, which links to electronic medical administrating record (eMAR) technology and patient tracking technology (e.g.

  • Publication number: 20140045140
    Abstract: A device for cleaning oral cavity and a method for cleaning oral cavity capable of cleaning stains such as plaque, tartar, and the like even in a narrow portion such as a clearance between teeth, a clearance between implants, and the like. A cover includes a jetting orifice and a discharge orifice and covers a tooth by leaving a clearance between the tooth and the cover so that the clearance can hold water. A jetting unit is mounted in the jetting orifice and includes a flow path communicating with the clearance between the tooth and the cover. The jetting unit is configured to generate cavitation bubbles. The flow path includes a small diameter part and an enlarged part. A discharge unit discharges water in the clearance between the tooth and the cover from the discharge orifice.

    Abstract: An oral care implement, e.g., toothbrush, having a wick applicator and a method of assembling the same is disclosed. The implement includes a head, a handle connected to the head by a neck portion, and a recess. The recess is arranged for receipt of the wick applicator. The handle includes an internal fluid reservoir holding a fluid in communication with the recess. The wick applicator is arranged to enable a fluid to pass therethrough by capillary action and has a first end portion and a second end portion. The second portion of the wick applicator comprises at least one projection for engaging at least one cooperating portion of the recess to secure the wick applicator in the recess at an operative position, whereupon the wick applicator is in fluid communication with the fluid in the reservoir.

  • Patent number: RE46696
    Abstract: A prophy cup has an outer surface with dimples formed therein. The dimples increase the turbulent flow in a boundary layer proximate to the surface. The increased turbulent flow reduces the separation of fluid (a slurry of saliva, blood and pumice) at the boundary layer to minimize the quantity of fluid ejected from the surface. A dental handpiece housing is configured to split longitudinally so that a wiper is positioned proximate to the outer surface of the prophy cup. The wiper removes slurry as the prophy cup rotates during a dental cleaning procedure to further reduce the quantity of fluid ejected from the surface during the procedure.
