Definitions

  • the subject invention is a prop for holding the mouth open to be used during oral surgery and during dental treatment and repair.
  • the device is particularly valuable when caring for an uncooperative or incompetent patient.
  • the prop can also be used for giving care to unconscious or mentally impaired persons.
  • U.S. Patent 3,924,333 discloses a dental appliance for evacuating debris and liquid from the mouth.
  • the device is a bite block with an opening in the transverse direction through the block to permit passage of a tube to provide for evacuation of the oral cavity.
  • the device is used with an attached dam. No handle for holding the device is seen.
  • U.S. Patent 4,167,814 discloses a bite block having a means for attachment of a suction tube that bends to provide a U-shaped portion with suction holes to evacuate fluid from the oral cavity. No handle extends outside the mouth for holding the device in place.
  • U.S. Patent 4,192,071 discloses a dam connected to a bite block through which there passes a tube for suctioning the oral cavity. The device is quite complex and lacks a handle for holding the device in place.
  • U. S. Patent 4,975,057 discloses a bite block with openings to admit suction tubing.
  • the device has an aperture in the transverse direction from the exterior of the bite block though the block into the oral cavity.
  • the device that enjoys continued use is the bite block of
  • Fig. 1 is a view of the prop device from the aspect which is medial when the device is in place.
  • Fig. 2 is a view of the block from the aspect which is lateral when the device is in place.
  • Fig. 3 is a view through the cross section of the prop when the block is in place between the jaws.
  • Fig. 4 is a medial view of the block in place.
  • Fig. 5 shows a cross section of the bite block with replaceable bite surfaces.
  • the purpose of the invention is to provide an improved device for supporting the jaws in the open position during dental surgery and treatment in a manner that will facilitate use of instruments by the dental practitioner and will protect the assistant from being bitten or injured by instruments in the patient's mouth during dental procedures while improving the comfort of the patient undergoing treatment.
  • the device is simple and economical enough to occasion wide use. Because the device is inexpensive, it can be sold as a disposable unit. Use of such disposable devices avoids expense of cleaning and spread of infection.
  • the device of the invention makes it much easier for the patient to relax his jaw muscles during prolonged dental procedures.
  • the device of the invention can also be used to prop the mouth open during application of medications to the back of the mouth and the throat or during collection of samples from that region. It would also be possible to use the device during lavage of the throat.
  • the device is also useful to care givers attempting to give oral hygiene to patients who are unable to cooperate with the care giver. Because the device is symmetri ⁇ cal, only one device is needed since it can be used in either side of the mouth. The devices could be provided for each patient for use with his other oral hygiene equipment.
  • the device of the invention consists essentially of a bite block with an elongated portion that is deflected to provide a turn of about 180° so that the elongated portion extends around the outside of the cheek with the end of the extension pointing backward from the mouth to form a handle by which the bite block is held in position. Because of the shape and position of the handle, the view of the dental practitioner is not obstructed by the hand holding the bite block in place. Furthermore, instruments introduced into the mouth do not come into close proximity with the hand holding the bite block in place. Since sharp instruments and needles can be a source of infection, the instant invention is useful in preventing spread of infection to care givers. Referring to the drawings, Fig.
  • FIG. 1 is a view of the device from the medial aspect, that is, the view from the side that is positioned against the tongue when the block is in place.
  • the surface against which the tongue will rest when the block is in use (1) (also referred to as the medial face or surface) may have a groove (4) which can hold a suction tube.
  • the block provides two bite surfaces (2) which may have ridges or other irregularities which increase efficiency of the grip when the block is in place.
  • the handle (3) is formed by the elongated portion extending from the block and bent at a 180° angle.
  • Fig. 2 is a view of the block from the lateral aspect, that is, the view from the side that is positioned against the cheek when the block is in use (5) (also referred to as the lateral face or surface) . Extensions from the medial and lateral faces of the block provide flanges (6) on either side of the bite surfaces which help to hold the block in place.
  • Fig. 3 is a cross section of the block in place between the jaws.
  • the ridges (6) hold the teeth against the bite surfaces (2) and the suction tube (7) is in position.
  • Fig. 4 provides a medial view of the block with the suction tube (7) wherein the tip of the suction tube (8) is resting against the floor of the side of the mouth beside the tongue (9) .
  • a suction tubing may be an integral part of the block, it is often more convenient simply to have a groove into which the suction tubing fits. This allows the dental practitioner to position the tubing as needed for the individual patient.
  • the bite block may have an opening in the transverse direction though which the suction tubing is passed.
  • the cap 10 is a rubber or rubber-like material that is a cap that fits over a protru ⁇ sion of the block.
  • the cap 11 fits over a smaller protrusion.
  • the bite body may have the indentation and the nipple may be on the bite cap. Any means by which a rubber cap may be fitted over a more rigid body would be appropriate.
  • the suction tubing when part of the block, may pass through the body of the bite block alone or may pass through both the handle and the bite block.
  • the use of a separate tube attached through the groove gives the practitio ⁇ ner greater latitude to adjust the suction tubing to meet the needs of the particular situation.
  • the drawings show a bite block having a groove with a tube lying within the groove, the suction tubing may be placed through a transverse aperture in the mouth block, with the tubing passing between the lips and transversely through the mouth block.
  • the devices of the invention can be made in several sizes for use with different patients. Because the blocks are symmetrical, they may be used on either side of the mouth. The devices may be used along with the traditional rubber dams or other isolation procedures used during dental treatment.
  • the bite block can be made of any material that will provide sufficient support for the jaw, preferred materials allow some deforming upon biting by the patient.
  • Such materi- als include resilient plastic or rubber materials.
  • a particu ⁇ larly preferred material is polystyrene which permits initial deformation to conform to the bite of the particular patient.
  • resilient materials such as plastics or rubbers (natural or synthetic) of varying rigidity.
  • the devices should be made of material that can be easily cleaned and sterilized. The method of sterilization may be chemical or physical (thermal, irradia ⁇ tion, ultrasound, etc.) and will depend on the equipment available and the material used to make the bite block.
  • a metal core covered with silicone rubber ⁇ like material or other similar material may be used.
  • the prop may be constructed of a strong, long-lasting substance such as metal or rigid plastic with detachable, replaceable bite surfaces of softer, deformable materials for long-term use for patients that can not cooperate with health care workers.
  • the device could be made with or without the groove for the suction tube. However, the device without the groove having a smooth surface would be more appropriate where suction was not needed, since a smooth surface would be easier to clean and sterilize.
  • the device may be provided with appropriate brushes and/or swabs, dental floss and compositions for oral care such as cleaning pastes or powders, lemon oil, and oral rinses such as Listerine or fluoride rinses in a kit form.
  • a kit could be provided for bedside use.
