A base shaft 4 with a built-in magnet is rotatably projected on a base 1. A rocking body 7 has a square substrate 8, a sphere 9, a sphere holder 10 rotatable around an axis which extends through the center of the substrate and perpendicular to the substrate, and a stopper for fixing the sphere holder at a desired rotational position. The sphere holder holds the sphere in such a way that the sphere is fixed at a desired rotational position. A stage is attached to the sphere through a support rod 20. A lower portion of the sphere protrudes downward from the sphere holder and substrate. The rocking body is magnetically coupled to the base shaft at a lower end of the sphere. An elevating body 21 is fitted on the base shaft and fixed by a set collar 22 at a desired height. The elevating body has a recess for receiving the lower portion of the sphere. The rocking body takes a horizontal position when the elevating body is brought into contact with the substrate of the rocking body, but takes a tilt position when a side of the substrate is brought into contact with an upper surface of the elevating body after the elevating body is lowered. An angle display mechanism 23 displays a tilt angle at the tilt position of the rocking body depending on the height of the elevating body.

DENTAL DEVICES AND SYSTEMS AND METHODS FOR MAKING THE SAME
20170325920 · 2017-11-16 ·

Dental devices and systems and methods for making dental devices are described herein. In some embodiments, denture base material may be adapted to fit a model of a patient's mouth, and a pre-set arch of denture teeth may be adjusted the model. The pre-set arch may be impressed into the denture base material to create a channel. In some embodiments, the cure may be a partial cure and/or a releasing agent may be used such that the pre-set arch may be removed, if needed for further adjustments, after assessing the fit of the denture device. If the fit is correct, another cure may be performed to finish the denture device. If the fit is incorrect, a new bite registration and/or adjustments to the denture base material and/or pre-set arch of denture teeth may be made.
