摘要： Anesthetic is delivered in a substantially continuous manner through a hole drilled in a jaw bone of a dental surgery patient. The hole is drilled in a conventional manner and a fixture embedded in the bone. An adapter is attached to the fixture and anesthetic is delivered substantially continuously through a tube connected to the adapter. An interference fit between the fixture and the adapter provides a liquid seal. The tube may be connected to the fixture by an interference fit, by adhesive or by molding.

摘要： A series of devices for medical, therapeutic and odontological treatments, which employ impulse-therapy or transcutaneous nervous electrostimulation as a means of physical, rational and non-invasive relaxation of specific muscle areas; the developed basic electrostimulating device consists of a triangular signal generator, followed by an amplifier, which is connected to a modulation controller. A squared signal generator is connected to a first stage conditioner which, in turn, is connected in parallel to a frequency divider, to a final amplifier, and to another second stage signal conditioner, and another final amplifier follows the latter. The referred frequency divider is also connected to a third stage signal conditioner through a key of three positions (A, B, C) which provides for varied frequency settings. A third stage signal conditioner is connected to a low frequency signal controller.

摘要： A dental apparatus for applying fluid to the teeth and gums includes as one of its principle components a U-shaped flexible, rubber-like tray having side walls and a bottom wall which define a channel into which the teeth and gums can extend. Attached to the inside perimeter of the side walls near the upper edge of the tray is a flexible, elastic tube. One end of the elastic tube is sealed. The other end of the elastic tube extends through the side wall at the front of the tray and is open for connection to a source of pressurized fluid for inflating the elastic tube. Attached to the bottom wall and communicating with the channel are conduit tubes. A method using the above apparatus to apply a fluid, such as an anesthetic, to the teeth and gums is also disclosed.

摘要： An improved manual pressure syringe for odontological use, includes a handgrip provided with a control lever, a barrel for a cartridge, and a bushing arranged on the longitudinal extension of the barrel. It also includes a shaft having a pushbutton at one end which is slidable in the bushing and acts on the piston of the cartridge, a thrust lever for the shaft operated by the control lever, and a coil spring arranged between the thrust lever and the bushing. The coil spring is formed of two end parts, the turns of which are of a larger diameter than that of the shaft, and an intermediate part, the turns of which are substantially of the same diameter as that of the shaft.

摘要： An absorbent insert of compressed matrix of absorbent material, including a filler dispersed therein to improve stiffness/rigidity of the insert and controls the absorbency of the compressed absorbent material. The insert is pre-shaped and sized for inserting into a tooth cavity, such as a pulp chamber or a root canal space. The compressed insert expands or swells upon absorbing fluid within the tooth cavity, so as to more completely dry the tooth cavity. The absorbent insert also serves as a substrate of an applicator for medical agent to be applied to a tooth cavity. The absorbent insert is provided (e.g., coated or impregnated) with a medical agent, which medical agent is released into the tooth cavity as the absorbent material absorbs fluid in the tooth cavity.

摘要： This disclosure relates to dental anesthetic delivery devices and associated methods for using the same. In certain embodiments, an anesthetic delivery device may comprise a pressure-driven needleless injector configured to deliver anesthetic deeply into the gingiva, allowing for a deep numbing and anesthetic effect and reducing pain from subsequent anesthetic injections and/or dental procedures. In some embodiments, the anesthetic delivery device may be T-shaped allowing for a shorter longitude axis length of the syringe body, improved clinician view of the oral cavity during use, single hand and/or ambidextrous use, and/or improved control during positioning.

摘要： A light for use with an oral anesthesia syringe that is received into a passageway of a barrel of the light. When the syringe is received into a first opening in a proximal end of the barrel's passageway, the needle of the syringe extends through a second opening at the proximal end of the barrel. At least one lamp and preferably a plurality of lamps at the distal end of the barrel illuminate the needle and the interior of a patient's mouth. A battery is included in the light for powering the lamps. The insertion of the syringe into the barrel may a pair of contacts to cause the battery to power the lamps, or the battery may be removed to remove power from the lamps. A disposable integrated syringe and light combination is also described.
