摘要： A manikin assists a student in learning to perform root canal therapy on a primary tooth of a child without damaging the underlying adult tooth bud. The manikin includes one or more inserts including a model of an upper primary tooth with roots and a lower adult tooth bud. The manikin includes a jaw portion that is receivable into a hinged dental training aid, so as to simulate the mandible or maxilla of the child. The jaw includes bony portions with a plurality of insert-receiving sockets. The bony portions are covered by an elastic simulated gum tissue that engages the primary tooth of an installed insert.

摘要： A dental articulator for use in dental education simulates the human mouth and has an adjustable hinge that interconnects upper and lower carrier trays for movement to and from a closed position. Modules of imitation gums and teeth are secured in the carrier trays by neodymium magnets. The hinge structure in the articulator is selectively movable to shift the jaw axis to a position to provide the desired alignment of the upper and lower teeth when the jaw is closed or demonstrate a misaligned condition. A dental training module may be installed which, upon removal from the articulator, has a pair of separable sections encasing a tooth to permit release of the tooth and removal from the module so that a completed treatment may be evaluated.

摘要： A dental training aid and method which assists a student in learning how to determine the position of a root canal apex, repair of dental decay, and how to perform crown and bridge procedures. In certain embodiments, modular inserts are utilized that include structure thereon for performing root canal procedures, repair of dental decay procedures, crown and bridge procedures or other procedures. The inserts can be assembled and configured to all provide practice on the same procedure or on different procedures and can be exchanged for other inserts once they are no longer reusable or because the user wants to train on a different procedure.

摘要： A fixture and method for use in dental training is disclosed which assists a student in learning how to determine the position of a root canal apex. The fixture and method include a tooth having a root canal and root apex with an electrically-conductive medium set around the root and root apex and securing the tooth in a fixture. An alternative embodiment uses first and second conductive mediums wherein the first medium is set around the root and root apex. The tooth is set into a fixture containing a second electrically-conductive medium. An electronic apical position locator is connected to an endodontic reamer and to the electrically-conductive medium in the fixture so that when the reamer is advanced through the root canal to the root apex, the electronic locator so indicates. Some locators are sufficiently sophisticated to indicate the distance of the reamer tip from the apex. In others an electrical circuit is closed causing the apical position locator to so indicate. The electrically-conductive media may be selected to be partially radiographically opaque to aid in the training of the use of the apical position locator. The conductive media is, selected to match or approximate the impedance levels of human tissue and correspond to impedance levels capable of being sensed by the electronic circuit of the apical position locator. Practice with this fixture and method enables a student to gain experience in determining the location of a root apex without the necessity to practice upon a live patient.

摘要： An endodontic probe system comprises a measuring kit of a plurality of flexible rods for insertion as probes into a root canal for determining the apical aperture diameter. Each rod has a tip end with a diametrally enlarged end ball structure so that a user obtains a precise tactile sensation when passing the end ball through the apical aperture. A variety of different end ball shapes are disclosed. Measurement of the apical aperture diameter is important to determine so that the root canal may be properly and entirely cleaned without unnecessary reaming or enlarging the diameter of the apical aperture.
