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

A viscous material such as an acrylic is added to the selected dental template and the dental template with the added viscous material is placed on the patient's alveolar edentulous ridge. The viscous material is then allowed to solidify to form a rigid or semi-rigid material with the template in proper position in three planes and properly border molded. After solidification a denture is formed that consists of a first base acrylic portion in conterminous relation with a second portion formed of the solidified material that had been added as a viscous material, and with teeth joined to the base acrylic portion.Type: ApplicationFiled: November 19, 2008Publication date: November 25, 2010Applicant: LARELL SURGICAL CONSULTANTS, INC.Inventor: Lawrence Norman Wallace

Publication number: 20100269836Abstract: Oral appliances adapted to for spacing the occlusal surfaces of the teeth of a user are disclosed. The oral appliances have an integral retention band interconnecting a first bite pad and a second bite pad. The first bite pad can include a first spacer and the second bite pad can include a second spacer that are configured to maintain the spacing of the occlusal surfaces of opposing teeth of a user during clenching or upon an impact to the jaw. Methods for the manufacture of composite oral appliances are also disclosed. The methods include forming a composite oral appliance over a model of a user's mouth.Type: ApplicationFiled: August 26, 2009Publication date: October 28, 2010Inventors: Mark Roettger, Robert C. Molhoek, Jon D. Kittlesen, Henry D. Cross, III, Paul A. Broadbent, Paul L. Bradshaw, Paul C. Belvedere, William L. Ballanoff

Patent number: 7819963Abstract: To provide a dental alginate impression material composition capable of solving a problem that the permeation rate of water with respect to the whole powder of an alginate impression material is slow at the time of use so that a kneading time is long and a sufficient operational time cannot be secured, and a problem that a kneaded material drops into a throat due to aging of the material at the time of taking an impression, the dental alginate impression material composition comprises 0.001 to 1% by weight of one or more kinds selected from oils mainly consisting of a fatty acid and an ester of alcohol, waxes mainly consisting of a fatty acid and an ester of glycerin, and a fatty acid ester; 0.01 to 10% by weight of a surfactant; and 0.01 to 10% by weight of one or more kinds of specific polysaccharides.Type: GrantFiled: August 29, 2007Date of Patent: October 26, 2010Assignee: GC CorporationInventors: Hiroshi Kamohara, Hiroki Morita

Patent number: 7806687Abstract: An occlusal state correction-supporting apparatus, a program therefor, and a recording medium thereof are provided, which can generate necessary, effective information in order to complete the shape of teeth excellently bitten. A shape-extracting means 10 extracts and stores shaped data of an upper jaw and a lower jaw. A position-extracting means 20 extracts and stores absolute coordinate data of reference points. A condition setting and distance-computing means 30 computes the distance between a upper jaw model 100 and a lower jaw model 200 while gradually bringing them close in a perpendicular direction. The condition setting and distance-computing means 30 also sets a condition of occlusal contact point, executes such approach movement again, and computes the distance.Type: GrantFiled: August 18, 2006Date of Patent: October 5, 2010Assignee: National University Corporation Okayama UniversityInventors: Shogo Minagi, Kazuhiro Oki

Publication number: 20100248180Abstract: A dental implant abutment arrangement for use with a dental implant has an abutment with a proximal retaining member and an axial bore. The retaining member is rotationally asymmetrical and has a transverse area that is large enough to resist rotation and axial motion of the abutment in a dental impression material. The axial bore has a tapered distal bore portion with an inner taper for matching an outer taper of an abutment receiving portion of an implant, a cylindrical proximal bore portion and an intermediate threaded portion having a small diameter than the distal and proximal bore portions and a larger diameter than an internal thread of the implant. The axial bore has distal and proximal steps between the distal bore portion and a distal end of the threaded portion and between the proximal bore portion and a proximal end of the threaded portion.Type: ApplicationFiled: September 9, 2008Publication date: September 30, 2010Inventor: Vitali Bondar

Patent number: 7789664Abstract: Apparatus and method enabling implant supported dental prostheses to be fabricated for reconstruction of both maxillary and mandibular arches from a procedure requiring only one surgery. At least three pairs of reference points in the maxillary arch and in the mandibular arch are connected by adjustable members which are subsequently fixed in length and in mutual orientation to enable necessary impressions and casts to be made. The adjustable members engage anchoring members such as ball headed screws which are fixed to the maxillary and mandibular anatomy. Subsequently fabricated mechanical models of the patient anatomy, such as impressions and casts, capture critical geometric relationships from the adjustable members and their associated anchoring members, thereby enabling both maxillary and mandibular implant mountable prostheses to be fabricated from information gathered during only one surgical session.Type: GrantFiled: February 16, 2007Date of Patent: September 7, 2010Inventor: Richard W. Toth
