Publication number: 20110129791Abstract: Certain embodiments of the present invention provide an apparatus to facilitate obtaining a dental impression including a compressible body. The compressible body has a top surface, a bottom surface, and an outer border. The bottom surface is configured to abut a maxillary dental impression tray. The top surface of the compressible body is configured to substantially contact and conform to a surface of a patient's hard palate. As the top surface contacts and conforms to the hard palate, it causes the compressible body to compress. The top surface forms a seal with the patient's hard palate. This seal discourages dental impression material from flowing into the patient's palatal vault. The seal may also discourage the dental impression material from flowing into the back of the patient's mouth. Consequently, the hydrodynamic pressure of the dental impression material may be advantageously increased and the patient's comfort may be reduced.Type: ApplicationFiled: November 26, 2010Publication date: June 2, 2011Inventor: Gary Rabinowitz

Patent number: 7704074Abstract: The present invention is a thermally formable plastic anatomical form for dentistry and a holder for the same. The holder is specially adapted to accommodate the plastic form in that it is heat resistant and features a bite guide to assure an even distribution of the plastic around the teeth of the patient and thickened occlusal surfaces to register specific tooth impressions more readily. The form according to the present invention may be used in any conventional dental work where a form may be needed, such as tray creation and stone molds, or may be utilized with therapeutic plastics so as to become a therapeutic dental device in and of itself.Type: GrantFiled: May 26, 2006Date of Patent: April 27, 2010Assignee: CAO Group, IncInventor: Steven D Jensen

Publication number: 20100021858Abstract: An injection correction impression tray (18) serves for producing dental impressions for the subsequent manufacture of crowns, bridges and other dental prostheses. The tray (18) includes a base body (23) containing impression material and a profile bottom plate (27). The plate (27) includes a first channel (41) and a second channel (43) being arranged in the bottom side of the plate (27). The plate (27) is connected to the base body (23) in a way to close the bottom opening (6) of the tray (18) and such that the bottom side and the channels (41, 43) face the interior of the base body (23). The first channel (41) forms a rib of a first impression material being introduced into the interior of the base body (23) and flowing through the bottom opening (6) into the first channel (41).Type: ApplicationFiled: September 11, 2009Publication date: January 28, 2010Inventor: Gerd Neuschäfer

Patent number: 7599538Abstract: 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 the at least one tooth is acquired using the intra-oral sensor and the spatial location information is automatically associated with the acquired digital image.Type: GrantFiled: July 24, 2006Date of Patent: October 6, 2009Assignee: Apteryx, Inc.Inventor: Kevin M.

Patent number: 7571727Abstract: A mouthguard includes two sections, a vertical component and a horizontal component. The foam is molded into a configuration such that the vertical component curves around the anterior section of the maxillary dental arch to the lateral aspects, just beyond the canine teeth. At the mouth temperature of 98.6 degrees F., the vertical component is held perfectly between the upper lip and teeth by the general pressure of lip musculature. There is a V-shaped notch in the midline of the vertical section to accommodate the maxillary labial frenum. The horizontal component provides a bite platform and a slit is located along the midline forming two rearwardly extending tabs to facilitate the curvature of the bite platform. Accommodative curvature of the vertical section is provided by spaces between the horizontal component and the ends of the vertical component forming deflectable wings in these regions.Type: GrantFiled: October 6, 2005Date of Patent: August 11, 2009Inventor: Theodore P Croll

Patent number: 7537451Abstract: A dental hygiene apparatus including a mouthpiece formed of a flexible arcuate channel defining and inner space designed for receiving an upper or lower set of human teeth. The channel is provided with longitudinally extending tunnels interconnected by communicating passageways. Each of the tunnels is provided with a longitudinally extending track and a guide slot communicating with the inner space. A carriage assembly includes motor assemblies joined by rigid chassis rods. The carriage assembly is designed such that the motor assemblies may be disposed in the tunnels while the chassis rods are disposed in the passageways. The motor assemblies have a shaft extending through one of the guide slots and carrying a rotatably mounted cleaning head on a distal end. The motor assemblies also include a driven wheel resting on a one of the tracks, for propelling the carriage assembly along the tracks. The cleaning heads rotate to clean the teeth and travel along the tracks to clean each tooth in sequence.Type: GrantFiled: November 29, 2007Date of Patent: May 26, 2009Inventor: Amrish Ramnarine
