Publication number: 20080096158Abstract: Impression trays for taking dental impression of a subject are discussed herein with particular discussion extended to impression trays know as triple trays. Triple trays are so coined for their ability to simultaneously capture the upper and lower impressions and the bite registration of a subject during a same dental procedure. The trays described elsewhere herein incorporate features that strengthen or increase the rigidity of the frame so that an impression taken of the dentition of the subject using one of the trays described elsewhere herein is not distorted and is therefore an accurate reflection of the true dentition.Type: ApplicationFiled: October 30, 2007Publication date: April 24, 2008Applicant: Discus Dental, LLCInventors: William Dorfman, Kasey Soll

Publication number: 20080064001Abstract: The present invention relates to a retracting device for retracting at least a portion of a user's mouth. The retracting device includes formations, which may be inter-engaging and/or non-inter-engaging with other dental tools or apparatus. The formations are adapted for repeatably positioning a subject's mouth with respect to a light system, and/or an imaging film, and/or a dental tray.Type: ApplicationFiled: October 30, 2007Publication date: March 13, 2008Applicant: DISCUS DENTAL, LLCInventors: William Dorfman, Robert Hayman, Eric Rose, Dennis Schroeder, Steve Piorek, Nancy Quan, Stuart Karten, Kenneth Rosenblood

Publication number: 20050171406Abstract: Retractors discussed herein include lip retractors that have four channel retainers to retain four portions of the lips. The four channel retainers are attached to four resilient members, which are adapted to bias the four channel retainers outwardly away from one another, which in turn retract the portions of the lips that are retained by the four channel retainers to expose the teeth and/or mouth. Optionally, the retractors may be equipped with a tongue retainer. If equipped, the tongue retainer is adapted to limit the tongue to further expose the backside of the teeth.Type: ApplicationFiled: February 21, 2003Publication date: August 4, 2005Inventor: William Dorfman
