  • Publication number: 20130122449
    Abstract: Fluid distributions implement to evenly wear down dental decay, diseased tissue, or undesired dentin in oral applications with live patients. The dentist has adjustable control over both the intensity and distribution field of a low-pressure sterile fluid, which may contain a pre-determined amount of reductive elements held in suspension. The implement must be supplied with a source of power and feed line of the chosen fluid. When switched on, it delivers one or a plurality of rapid bursts of varying impact strength in such a quick manner that the entire impact zone receives an even distribution of the liquid bursts. The desired result is the severe reduction in cratering, gouging, and non-symmetrical damage introduced by implements of the prior art such as drills, jet-stream fluid delivery systems, and tissue sanders with less danger of structural impairment to the patient in these cases of comparison.

  • Publication number: 20120082952
    Abstract: Method for expanding bone crest (1) in order to receive the installation of a final dental implant (4), where the bone crest (1) is expanded using a implant-expander, in other words, a biocompatible and osteoconductive piece that has an expander function. The use of an implant-expander (3) to widen the bone crest (1) has the important effect of said implant-expander acting as a support to the bone and therefore helping to consolidate the fracture of the bone crest (1) and the formation of bone around said implant-expander. The bone generated around the implant-expander (3) is therefore of a high quality. The invention also contemplates the optional correction of the angulation of the alveolus during the widening process, so that the final dental implant (4) and the corresponding dental prosthesis are adequately oriented. It is also an object of the invention to provide a specific design for the implant-expander (3).

  • Publication number: 20110207990
    Abstract: The present invention relates generally to the design and optimal placement of transmitting and receiving directional antennas, a priori, as used in intra-oral to extra-oral (or visa versa) wireless electronic systems regardless of the type and purpose of the data transmitted between the antennas (intra-oral and extra-oral). Systems related to the invention transmit data via electromagnetic radio waves or through an inductive loop coupling such as in stimulating the human hearing nerve (inner ear) via dental bone conduction pathway when operating in “receive mode”. “Send mode” systems related to the invention transmit non-acoustic information or voice data from inside the mouth to a receiver located outside the mouth.

  • Publication number: 20110207075
    Abstract: A method comprises creating a predetermined pattern of treatment microzones in oral tissue affected by a condition, applying energy of predetermined characteristics to the soft tissue through a tip being limited by at least one dimensional feature of the oral tissue. The application of energy to the oral tissue after creating the predetermined pattern of treatment microzones in the oral soft tissue is terminated. A type of the energy and the characteristics of the predetermined pattern of treatment microzones are defined by the condition in the soft tissue. The condition in the oral tissue can be a gingival recession, gingivitis, periodontal disease, xerostomia, black triangle disease, and interdental/interimplant papilla deficiencies. The oral tissue can be oral soft tissue, such as oral mucosa soft tissue or a gingival soft tissue.

  • Publication number: 20110177471
    Abstract: In a method and apparatus for detecting a crack in a human tooth, especially one covered by a restoration, such as a crown, the approach is to stress the suspect tooth and, by means of acoustic emission techniques, analyze the characteristics of the resultant acoustic emission from the tooth. To aid the identification of a crack from the acoustic emission signal, a baseline may be obtained by performing this procedure at a time when the tooth is known not be cracked, e.g., when a restoration is placed on it. This baseline acoustic emission signature is recorded. This procedure is repeated at intervals. The subsequent measurements are compared with the baseline to identify changes that indicate the initiation and growth of a crack. The invention includes apparatus for implementing the method. The approach is to integrate the acoustic emission pulser and sensor into commercially available dental instruments, e.g., a tooth polisher and a water syringe.

  • Publication number: 20110129787
    Abstract: A method for creating a custom dental tray is made by filling a dental tray with an elastomer material, obtaining a first impression of a patient's teeth in the elastomer material by pressing the elastomer-filled dental tray against the patient's teeth, heating a polymer sheeting, and placing the heated polymer sheeting over the first impression in the elastomer-filled dental tray. In addition, the custom dental tray is made by obtaining a second impression of the patient's teeth in the polymer sheeting by pressing the elastomer-filled dental tray having the first impression and the heated sheeting over the patient's teeth and removing the polymer sheeting from the elastomer-filled dental tray.

  • Publication number: 20110059416
    Abstract: Provided is an assistant apparatus for oral treatment including dental treatment and a unit chair equipped with the same. The assistant apparatus includes an oral cavity insertion member positioned in the oral cavity in front of the uvula of a patient, or preferably, on the soft palate, such that washing liquid or saliva is prevented from entering a patient's throat during oral treatment. Therefore, it is possible to prevent patient discomfort and interruption of treatment. Further, medical instruments/components are prevented from entering the throat and injuring the pharynx.

  • Publication number: 20110045429
    Abstract: A dental prosthesis removal tool comprising a handle portion and a top portion, the top portion comprising a head portion and a beak portion. The beak portion is configured to engage both a maxillary dental prosthesis and a mandibular dental prosthesis without the tool needing to be reoriented. The dental prosthesis removal tool makes it possible for a dental prosthesis wearer to remove dental prostheses without the user placing his or her fingers inside of his or her mouth. The dental prosthesis removal tool also allows a denture wearer to remove dental prostheses without bending, work hardening, or breaking metal clasps contained in some dental prostheses. The dental prosthesis removal tool further allows a denture wearer to more comfortably remove his or her dental prosthesis, promoting better patient compliance with maintenance procedures and oral hygiene.

  • Publication number: 20110008746
    Abstract: A liquid injection apparatus for lifting a maxillary sinus mucous membrane includes a passageway longitudinally extending through inside the apparatus; a connecting pipe formed at a rear portion to connect with a liquid supply apparatus; and an injection pipe 16 formed in a front portion, for being inserted into an implant hole extending to a bottom of a mucous membrane of a maxillary sinus, with a distal end of the injection pipe 16 spaced apart from the mucous membrane by a predetermined distance. The injection pipe is structured to inject liquid into the implant hole while closing the implant hole. The liquid injection apparatus can more easily lift the maxillary sinus mucous membrane without damaging the same by applying uniform pressure to the maxillary sinus mucous membrane when the maxillary sinus mucous membrane is being lifted.
