Title: Aligning assembly for use in dentistry

What is claimed as new and desired to be protected by Letters Patent is set forth in the appended claims:

1. A method of determining correct mandibular position, particularly in prosthodontic and orthodontic work, comprising the steps of providing two prefabricated flat, rigid plates of a standard shape exceeding the inner contour of the parient's gums, and made of plastic material, one of said plates having a projection thereon; marking said plates according to the inner contour of existent teeth; adjusting the edges of the plates by cutting off the portions thereof exceeding the marked contours; positioning the adjusted plates in the oral cavity to rest on the upper gum and the lower gum, respectively, whereby the projection abuts the other plate; having the patient move his jaws from opposite directions until the projection provides a centering mark on the other plate; removing at least the other plate from the oral cavity; forming a recess in the place of the centering mark; repositioning the other plate in the oral cavity; having the patient move his jaws until the projection partially enters the recess; and connecting the plates to each other to form a compact aligning assembly prior to the removal thereof from the oral cavity.

2. A method of determining correct mandibular position particularly in prosthodontic and orthodontic work, comprising the steps of providing two prefabricated, substantially flat, rigid plates of a standard shape and made of plastic material, one of said plates having a bore therein, and an externally threaded pin fixed in the bore, the free end of said pin being of ball-shaped configuration; marking the edges of said plates according to the inner contour of existent teeth; adjusting the edges of the plates by cutting off the portions thereof exceeding the marked contours; positioning the adjusted plates in the oral cavity to rest on the upper gum and the lower gum, respectively whereby the ball-shaped end of the pin abuts the other plate; having the patient move his jaws from opposite directions until the ball-shaped end provides a centering mark on the other plate; removing at least the other plate from the oral cavity; forming a bore having a diameter slightly smaller than the diameter of the ball-shaped end in a place determined by the centering mark; repositioning the other plate in the oral cavity; having the patient move his jaws until the ball-shaped end partially enters the bore; and connecting the plates to each other by synthetic plastic material to form a compact aligning assembly prior to the removal thereof from the oral cavity.
