Abstract
(EN)
A shell-shaped dental instrument (500) for correcting occlusal interference, being an integral shell shape, having a cavity (501) for accommodating multiple teeth of a first dentition (301), and being raised toward the jaw in the area between the cuspids and the molars to form a jaw pad (503), used for opening the first dentition (301) and a jaw dentition (303) to a sufficient extent in order to relieve the obstruction of the anterior teeth of the jaw dentition (303) to the adjustment of the anterior teeth of the first dentition (301); the cavity (501) has a geometric shape for repositioning the multiple teeth from a first layout to a second layout, the position of the anterior teeth in the second layout being different to the position thereof in the first layout.
