Abstract
Abstract A vise for transfer of check-bites characterized in that clutches fastened to the respective upper and lower arches of the patient's teeth or to the patient's alveolar ridges have screw-actuated vise means which, when loosened, enable protrusive and right and left excursions of the mandible, said vise means being tightened after each such excursion to lock the clutches in the respective check-bite positions for adjusting a dental articulator.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
101 words
A vise for transfer of check-bites of a dental patient to a dental articulator comprising upper and lower center bearing plates carrying clutches fitting the patient's upper and lower arches and having forwardly extending exterior portions; upper and lower transverse bars having spherical ends secured between said ends to the respective exterior portions; the spherical ends of said lower transverse bar being spaced below the corresponding spherical ends of said upper transverse bar; and screw-actuated vise means spanning the corresponding ends of said bars for releasably frictionally gripping said spherical ends in any selected check-bite position of said plates and clutches.
Claim 2
Dependent Claim
101 words
A vise for transfer of check-bites of a dental patient to a dental articulator comprising upper and lower center bearing plates carrying clutches fitting the patient's upper and lower arches and having forwardly extending exterior portions; upper and lower transverse bars having spherical ends secured between said ends to the respective exterior portions; the spherical ends of said lower transverse bar being spaced below the corresponding spherical ends of said upper transverse bar; and screw-actuated vise means spanning the corresponding ends of said bars for releasably frictionally gripping said spherical ends in any selected check-bite position of said plates and clutches.
Claim 3
Dependent Claim
25 words
The vise of claim 1 wherein each vise means comprises a pair of screw-actuated curved jaws which releasably frictionally grip said corresponding spherical ends therebetween.
Claim 4
Dependent Claim
24 words
The vise of claim 1 wherein said transverse bars carry cooperating tracing plate and styli means for recording jaw excursions for the respective check-bites.
Claim 5
Dependent Claim
21 words
The vise of claim 2 wherein each pair of jaws is screw-actuated by screw means thereacross between said corresponding spherical ends.
Claim 6
Dependent Claim
41 words
The vise of claim 4 wherein each pair of jaws has retaining means thereacross above the spherical end of said upper transverse bar to retain said jaws in downwardly depending relation for straddling the spherical end of said lower transverse bar.
Claim 7
Dependent Claim
34 words
The vise of claim 1 wherein one of said plates has a center bearing stud engaging the other one of said plates to space said plates apart a predetermined distance in all check-bite positions.
