Abstract
A method and apparatus for treating hard dental substances wherein the work can be carried out in an indirect technique uses an intraoral video camera, whose images are reproduced on a monitor. To accomplish this and to prevent particles and bacteria in the patient's mouth from being spread, the apparatus includes a shielding which is arranged on the patient's mouth to prevent the emergence of particles but to allow the insertion of the treatment handpieces, the camera into the mouth and to the treatment location.
