  • Patent number: 9844324
    Abstract: An image guidance system for tracking a surgical instrument within the oral cavity. The image guidance system includes a plurality of cameras adapted to be located within the oral cavity to provide intraoral images of optically visible patterns within oral cavity. A processing system receives and processes the intraoral images to recognize patterns and triangulate the locations and orientations of each camera. The processing system uses a reference dataset which defines a reference coordinate system based on alignment to a portion of the oral anatomy. The processing system determines the location and orientation of the tracked instrument based on the reference dataset. In an embodiment, the system includes an oral fixture that is removably attachable to teeth in a patient and is configured to hold one of the cameras.

  • Publication number: 20150118640
    Abstract: An intra oral dental device and method for recording the 3D envelope of motion of a patient and translating the recording into digital information used to diagnose, computer design and manufacture dental restorations. The dental device is comprised of upper and lower tracing members having tracing pins on one member and complementary recording material on the other. The method includes forming a set of intra oral gothic arch tracings to define the 3D envelope of motion, converting the tracings to a digital data set reproducing the motion, and using the data to create a virtual model of the patient and the jaw motion. The data is used to mill articulator housings to reproduce jaw motion, to virtually position and shape virtual teeth in conformity with the patient's jaw motion, and to mill the completed dental prosthesis insuring teeth contacting surfaces are in harmony with the patient's jaw motion.

  • Patent number: 8978659
    Abstract: A dental device has a U-shaped carrier with at least one channel for embracing an arch of teeth. There are recessed insets in the channel. Discrete inserts carrying a beneficial agent can fit into the insets and release the agent gradually. The device may be used in a therapeutic application and as an athletic mouthguard. Temporary blanks may be initially fitted in the insets, while a portion of the mouthguard is softened before an arch of teeth is pressed into the channel to make a custom impression. The inserts possess different physical properties than the carrier and may be positioned and shaped to mechanically buffer teeth of the arch from mechanical shocks as well as release beneficial agents. The inserts may be replaced or refreshed to maintain the beneficial agent. A dental device having a core carrying a beneficial agent inside a liquid-permeable shell functions as an infant's teething device.

The dental impression apparatus includes a support frame of a predefined shape, a partially permeable membrane mounted on the support frame, and absorbent barrier members. The support frame includes a distal member, a buccal edge member, and a lingual edge member. The absorbent barrier members mounted to the buccal edge member and the lingual edge member of the support frame define opposing troughs separated by the partially permeable membrane. The opposing troughs receive the patient's mandibular teeth and maxillary teeth. The opposing troughs are deposited with a first impression material and/or a second impression material for obtaining the dental impression of the patient. The absorbent barrier members confine a flow of the first impression material and the second impression material within the opposing troughs, when the patient applies a biting force within the opposing troughs.

  • Publication number: 20150010879
    Abstract: In an exemplary embodiment, a method of creating an impression of structures of the human oral cavity comprises: preparing impression trays: creating a first, or base, impression; grinding out portions of the base impression; and using the void(s) in the ground out base impression to take a second, or wash, impression. The base impression is taken with an excess of a high-density impression material which is positioned to extend beyond the structures of interest (of which the impression is being taken). The base impression is removed and all fine structure surrounding the structure(s) of interest is ground out. A wash impression is then taken using a low-density impression material. The base impression creates a seal around the structure(s) of interest (a closed system), thereby producing omnidirectional hydraulic pressure on the low-density material. Such omnidirectional hydraulic pressure produces a highly detailed final impression from which a high-quality model (e.g., cast) can be made.

  • Patent number: 8505541
    Abstract: A dental device has a U-shaped carrier with at least one channel for embracing an arch of teeth. The carrier has recessed insets in the channel. Discrete inserts carrying a beneficial agent can fit into the insets and release the agent gradually. The device may be used in a therapeutic application and as an athletic mouthguard. Temporary blanks may be initially fitted in the insets while a portion of the mouthguard is softened before an arch of teeth is pressed into the channel to make a custom impression. The inserts possess different physical properties than the carrier and may be positioned and shaped to mechanically buffer teeth of the arch from mechanical shocks as well as release beneficial agents. The inserts may be replaced or refreshed to maintain the beneficial agent. A dental device having a core carrying a beneficial agent inside a liquid-permeable shell functions as an infant's teething device.

  • Patent number: 8312884
    Abstract: An intra-oral device used for people that snore or have sleep apnea is designed to move a user's lower jaw forward relative to the user's immovable upper jaw and to prevent the user's mouth from inadvertently opening while sleeping. The device includes upper and lower appliances fitted to the user's respective upper and lower dental arches. The lower appliance possesses a partially embedded bracket. An adjustment element is integrated into the upper portion of the bracket. With the user's mouth closed and the upper and lower appliances positioned over the user's respective dental arches, the adjustment element is moved rearward by worm action into load bearing contact against the forward facing immovable vertical contact wall of the upper appliance. This action moves the lower appliance forward, and thus, the user's lower jaw with its anatomically attached tongue are also moved forward relative to the mouth which in turn opens the user's airway.
