The elongated arm extends towards and couples with a rear portion of the receptor holding member, opposite the collimation plate, such that an unobstructed path is defined between the substantially rectangular opening of the collimation plate and the receptor. A biting surface is fixedly attached to a distal end of the elongated arm and adjacent to the receptor holding member such that the receptor is positioned behind the teeth on which the radiographs are being taken while the biting surface is gripped by the teeth on the opposite side of the patient's mouth.Type: GrantFiled: March 24, 2003Date of Patent: June 6, 2006Inventor: Jennifer A. Diederich

Patent number: 7033075Abstract: A radiographic sensor retention apparatus for retaining a radiographic sensor and allowing it to be properly positioned within the mouth of a dental patient during x-ray image registration. The apparatus is held in position within the mouth of the patient in response to biting pressure from the upper and lower dental surfaces, and comprises a bite block with an extending first jaw member, a second jaw member slidably engaged with the bite block, and a threadable member connecting the second jaw member to either the bite block or the first jaw member, wherein the separation between the jaws is continuously variable in response to the rotation of the threadable member. Compliant members are preferably joined to one or both of the jaw members to aid in distributing the retention forces and to reduce sensor slippage. The bite block is preferably configured for the attachment of at least one alignment guide.Type: GrantFiled: November 25, 2003Date of Patent: April 25, 2006Assignee: OP-D-OP, Inc.Inventors: Timothy J. Landis, Clay D. Allen

Patent number: 6974253Abstract: In an arrangement for connecting a dental X-ray imaging sensor to a holder; the sensor (9) is a flat piece (11) having a planar radiation sensitive area, and at least one communication line (12) connected to said radiation sensitive area for data transfer; and the holder (8) is an elongated body having a first end provided with means for detachable connection of said sensor. The sensor has a peg (3) projecting from said flat piece. The peg is provided with a widened outer end and a neck between said outer end and said flat piece. Further, the neck has a configuration with a plurality of alternate larger diameters and smaller diameters. The holder has at its first end a fork (4) with a gap, which is adapted to fit onto said neck at least in two different positions. The interaction between the fork and the larger and smaller diameters of the neck prohibits unintended pivot of said sensor in respect to the holder.Type: GrantFiled: April 12, 2004Date of Patent: December 13, 2005Assignee: Instrumentarium Corp.Inventor: Pekka Ihalainen
