Abstract: Airway assist device (AAD) is provided. The device includes an upper AAD component and a lower AAD component. The upper AAD component includes and upper tooth guide connected to an upper plate. The upper AAD component further includes an upper force receiving plate. The AAD also includes a lower AAD component. The lower AAD component includes a lower tooth guide connected to a lower plate. The lower AAD component further includes a lower force receiving plate. The upper and lower AAD components are connected in a way that allows relative movement between the two components between a neutral position and a plurality of extended positions to protrude and distract a patient's mandible. A ratchet mechanism inhibits movement of the lower plate from any extended position. The ratchet mechanism may be manually disengaged to allow the lower AAD component to return to the neutral position. The lower AAD component includes a chin guide.

Abstract: A dental tray for use in taking an impression of a person's teeth is provided. More particularly, the dental tray includes a first section having a longitudinal axis and a second section sized and shaped so as to be mounted at least partially within the first section. The first and second sections are sized and shaped so as to define a trough therebetween for receiving an impression-taking material. The second section is adapted to move relative to the first section in a first direction substantially parallel to the longitudinal axis of the first section. The second section has at least one member movable in a second direction substantially perpendicular to the first direction in response to the movement of the second section in the first direction.

Abstract: The mouthpiece (10) includes receiving portions for receiving teeth from the upper and lower jaws. The teeth receiving portions includes two side portions (26, 28) which are joined by flexible members (32, 34) to a front portion (30). The two side portions move laterally relative to the front portion by the flexible members to accommodate a variety of dental arch configurations.

Abstract: A method and systems for capturing digital intra-oral images, while automatically determining a location of an intra-oral sensor placed within a mouth of a patient, is disclosed. A spatial frame-of-reference is established with respect to teeth within the mouth of the patient. An intra-oral digital imaging sensor is placed within the mouth of the patient adjacent to at least one tooth within the mouth that is to be imaged using the intra-oral sensor. Spatial location information is automatically generated such that the spatial location information defines how the intra-oral sensor is placed with respect to the spatial frame-of-reference. A digital image of at least one tooth is acquired using the intra-oral sensor and the spatial location information is automatically associated with the acquired digital image. The associated spatial location information may be used to automatically correlate the acquired image to a tooth or teeth within the mouth and/or to automatically orient the acquired image for display.

Abstract: A method and accompanying apparatus that allows high concentrations of hydrogen peroxide for tooth whitening by use of an aerosol spray. The aerosol spray may be delivered through a mouthpiece that will direct the spray onto the teeth while inhibiting any escape of the spray to the lips and outside the moth. Also, in combination with antiplaque formulations, enhanced tooth whitening is effected.

Abstract: An adjustable dental impression tray including a first arcuate member and a second arcuate member configured to selectively engage the first arcuate member. The first and second arcuate members forming a channel adapted to receive a quantity of impression material. The adjustable dental impression tray having a handle formed at one end which facilitates the introduction and removal of the impression tray into and from the mouth of a patient. An adjustment mechanism engageably disposed in relation to the first and second arcuate members, wherein the adjustment mechanism provides for the selective adjustment of the first arcuate member in at least one fixed position relative to the second arcuate position, wherein defining one or more widths of the channel. Preferably, the channel is formed having a general U-shaped configuration which approximates the various sizes of the dentition of a patient. In preferred design, each of the arcuate members comprise an outer wall, an inner wall and a platform surface.

Abstract: An improved device for registration of dental bite provides a possibility to make accurate impression of the patient's dental bite and includes the first portion and second portion. The first portion comprises a first mouth portion and a first handle portion, and the second portion includes a second mouth portion and a second handle portion. Each of the first mouth portion and second mouth portion are generally of half-U-shaped configuration, and in the coupled position form the U-shaped configuration. Also, the device comprises the connector located in the handle portions of the first portion and second portion respectively, and which includes a first connecting portion located on the first handle portion and the second connecting portion located on the second handle portion.

Abstract: Dental impression trays for obtaining an impression of an arch by using the impression material according to this invention are characterized by comprising: a maxillary tray (10), which is adjustable according to the arch size by forming a U-shaped stray curved in the arch form for receving the impression material with resprectively extended hinge plates (12) being fixed to its center where the tray is divided into two and with fastening pants being engaged with said hinge plates (12), and a mandibular tray (20), which is adjustable according to the arch size by forming a U-shaped tray curved in teh arch form for receiving the impression material with respectively extended hinge plates (12) being fixed to its center where the tray is divided into two and with fastening parts being engaged with said hinge plates (12).

Abstract: A gel tray for holding a medicament to be applied to the teeth and gums of a patient includes a handle and an opposing buckle. In one embodiment, the buckle includes a tongue portion and a retainer strip surrounding the tongue portion so as to define a narrow space between the tongue portion and the retainer strip, the narrow strip having a width less than the thickness of the handle. The handle has a tongue reception groove extending transverse to its length at a position such that the tongue reception groove is engaged by the tongue when the tray is folded. In another embodiment, slotted tabs are interfitted when the tray is folded. The tray may therefore be securely maintained in the folded state. The tray can be combined with or preloaded with a treatment agent such as a gel comprising a pharmaceutically effective amount of at least one agent for treating teeth or gums dispersed in a gel medium consisting essentially of water and an amount of a water dispersible gelling agent sufficient to form a gel.

Abstract: An edentulous impression correlator includes a support of adjustable configuration and a handle. The support is adjusted to fit an individual patient's mouth and a quantity of impressionable material placed on it. Then the support and material is positioned within the patient's mouth, with the handle protruding, and an impression is made to form a bite record including the upper vault and the lower ridge crest. The support is removed from the mouth and the material is removed from the support by sliding it over the handle.
