Abstract
A training machine for intra-oral instrumentation for dental treatment which comprises a plate carrying an electrically conductive path on the surface thereof; an imitation dental instrument with an imitation dental tool detachably attached thereto, so that a trainee traces said conductive path with said tool; and means for measuring the time during which said conductive path is being traced with said tool. A shield is attachable to the machine so that the trainee can look at the pattern of the conductive path either directly without the shield or only through a mirror with the shield attached to the machine.
Claims20
A training machine for intra-oral instrumentation for dental treatment, comprising a plate carrying an electrically conductive path on the surface thereof;
- an imitation dental instrument with an imitation dental tool detachably attached thereto, so that a trainee traces said conductive path with said tool;
- means for measuring the time during which said conductive path is being traced with said tool;
- and means for shielding said plate so that said plate is visible to said trainee only through a mirror.
A training machine for intra-oral instrumentation for dental treatment, comprising a plate carrying an electrically conductive path on the surface thereof, an imitation dental instrument with an imitation dental tool detachably attached thereto, said tool being interchangeable with a different imitation tool, so that a trainee traces said conductive path with said tool;
- and means for measuring the time during which said conductive path is being traced with said tool.
