Abstract: A dental space and periodontal cavity measuring instrument for insertion in interdental or interproximal spaces between teeth and in periodontal cavities in both the upper and lower dental arches to determine the width of such spaces and the depth of the cavities, respectively, for appropriate treatment. The dental space and periodontal cavity measuring instrument is characterized by a centrally located handle provided with a pair of oppositely-extending single tips or multiple, elongated, graduated cylinders which terminate in graduated ends, for insertion in the interdental spaces and periodontal cavities. The calibrated cylinders and graduated ends may be extended in a straight line from the handle, or one or more cylinders in one or both of the calibrated and graduated tips may be angulated and the diameter of each cylinder may be indicated on the handle for size-identification purposes. The ends of the cylinder or stem tips may also be "waffled" with striations for ligature tucking purposes.

Abstract: A personal information carrier (10) having a radiographically readable code (12) uniquely identifying a person which is installed in a cavity (34) in the side (30) of the person's tooth (32) which is then filled with a radiolucent composite filler (50) to protectively seal the carrier (10) within the cavity (40). Detecting the location of a missing child is achieved by using a filler (50) which matches the color of the surrounding tooth surface (30) to conceal the presence of the personal information carrier (10) from a potential kidnapper and distributing the code (12) of the missing child to the authorities and professional dental community. Amnesics and corpses are also identified by radiographically reading the carrier (10) and comparing the code (12) to a list of codes (12) of missing persons which are listed in alphanumeric order.

Abstract: A system and method is provided for implanting tooth analogues in the jawbone resulting in aesthetically and functionally desirable gingival tissue contours after restoration. The system permits modification and adaptation of the tooth analogue to meet intraoral demands in a manner similar to that used in the preparation and restoration of natural teeth. The system comprises a standard fixture and cover screw passed through opened gingival tissue and implanted in the jawbone. After the osseointegration of the fixture, the gingiva is reopened, the cover screw removed and a healing cap having a predetermined contour, is attached to the fixture. The reopened gingiva re-heals in a shape determined by the contour of the healing cap. The healing cap is then removed and replaced by an abutment having an emergence profile matching that of the healing cap. An immediate snug fit between the gingival tissues and the abutment is thereby provided at the time of connection of the abutment to the fixture.

Abstract: A device for supplying individual ligature wires inserted as a pack of wires in a casing of the device has an operating arm. A pack of ligature wires is inserted into a recess provided in the casing. Pressure is exerted onto the pack of wires by a push rod. In each case the lowermost ligature wire in the pack is pressed into a recess formed in the bottom of the casing. Then the wire from this readiness position is advanced into a transfer position by a driving pawl mounted in a slide. The movement is carried out by pressing the operating arm, the free end of which projects into a slot of the slide and, on pressing the operating arm, advances the slide and therefore the ligature wire into the transfer position. In the transfer position, the end portions of the ligature wire can be grasped by a tool, e.g. a twister and removed from the casing to be placed into the area of use.

Abstract: A dental appliance safety-line consists of a line, one end of which contains a flexible vinyl handle and with an attachment end. The vinyl handle is used to grasp onto and manipulate the safety line, and the attachment end provides an adequate amount of retentive surface area for an adhesive to penetrate and adhere to and imparts substantial strength between the safety line and a dental device such as a dental restoration or appliance. The safety line is left attached to the dental device during the fitting and adjustment procedures. Once the dental device is permanently affixed in the oral cavity, the chair side practitioner takes any readily available instrument and removes the safety line by cleaving the adhesive at the junction of the attachment end and surface of the dental device. This removal is accomplished without the need for modifying or refinishing the surface of the dental device.
