Interactive, computer based orthodontist treatment planning, appliance design and appliance manufacturing is described. A scanner is described which acquires images of the dentition which are converted to three-dimensional frames of data. The data from the several frames are registered to each other to provide a complete three-dimensional virtual model of the dentition. Individual tooth objects are obtained from the virtual model. A computer-interactive software program provides for treatment planning, diagnosis and appliance from the virtual tooth models. A desired occlusion for the patient is obtained from the treatment planning software. The virtual model of the desired occlusion and the virtual model of the original dentition provide a base of information for custom manufacture of an orthodontic appliance. A variety of possible appliance and appliance manufacturing systems are contemplated, including customized archwires and customized devices for placement of off-the shelf brackets on the archwires, and removable orthodontic appliances.

A combination mouth and nasal mask (40) for assisted respiration or CPAP is disclosed. The combination mask (40) has a frame (42) to the rear side of which is mounted a separate nasal cushion (44) and mouth cushion (46). Both the nasal cushion (44) and the mouth cushion (46) separately form a rolled edge seal around the patient's face in the vicinity of the nose and in the vicinity of the lips. Inlet air is communicated from within the housing (48) to the mouth chamber, circumscribed by the mouth cushion (46) by means of one or more interconnecting tubes (62). The proportion of air communicated to the mouth chamber (48) is controlled by the sizing and number of the tube(s), thus providing for free flow of air, restricted flow of air and pressure equalization, or zero flow of air. A mouth mask (10) for assisted respiration or CPAP also is disclosed.

A medical treatment method comprises orally inserting a first endoscope having a first treatment tool provided thereto into a body cavity, inserting a first insertion member insertion support tool from at least one of abdominal and transdermal cavities into the body cavity, inserting a second endoscope having a second treatment tool provided thereto into the body cavity through the first insertion member insertion support tool, grasping a lesioned part by the second treatment tool inserted into the body cavity by the second endoscope, cutting the lesioned part by the first treatment tool inserted into the body cavity by the first endoscope, and collecting the lesioned part.

A patient interface for communicating fluids to and/or from a patient's nasal cavity and/or oral cavity is disclosed. In addition, a patient interface for fluid and physiological function monitoring proximate to the patient's nasal cavity and/or oral cavity is disclosed. An apnea monitor and a method for monitoring apnea are also disclosed.

An oral hygiene device including, in combination, a system for relatively effortlessly and effectively cleansing dental, inter-dental, gingival and deep-gum surfaces and crevices, and a convenient teeth bleaching system that may be selectively implemented following cleansing of the oral surfaces, wherein the present invention may be utilized in conjunction with, or in lieu of, conventional brushing and/or flossing practices.

Systems and related methods treat snoring and other sleep related disorders by stabilizing the position of a tongue in an oral cavity. The systems and methods employ an operative element sized and configured to be fitted to less mobile tissue in the oral cavity. The operative element is further constructed and arranged to interact with a tongue in the airway to stabilize a preferred tissue orientation. The operative element can comprise a suction source sized and configured to draw more mobile tongue tissue toward the suction source. The operative element can comprise a magnetic source sized and configured to magnetically attract material fitted to more mobile tongue tissue in the airway.

A method for providing data useful in procedures associated with the oral cavity, in which at least one numerical entity representative of the three-dimensional surface geometry and color of at least part of the intra-oral cavity is provided and then manipulated to provide desired data therefrom.

An oral care implement with a handle includes a head with a tissue cleanser. The tissue cleanser may be a pad composed of an elastomeric material. The pad is disposed on the head on a surface opposite the tooth cleaning elements. The tissue cleanser may include a plurality of nubs extending for cleaning between the papillae of the tongue. The tissue cleanser may include a plurality of conically shaped nubs. A tissue cleanser can be used to reduce oral malodor problems and remove oral epithelial cells.
