Abstract
The present dental articulator provides a means for correcting most incorrect bites after the models have been mounted and permits the model to be removed and placed on another similar articulator in the same position. An articulator frame comprises a base having opposed side frame members but supports a pivoting frame attached thereto by pivot pin and coil spring arrangement. A bottom bracket removably mounted on the base supports a U-shaped model bar for the lower model with adjustment means thereon removably supporting the model frame. An upper bracket on the pivoting frame removably supports a U-shaped upper model bar for adjustment thereon. The upper and lower models are mounted and adjusted in fixed position and then may be removed and sent without the articulator to be remounted later in a similar articulator.
Claims19
In a dental articulator for mounting a dental model comprising upper teeth and lower teeth:
- a base frame having means thereon for supporting the base stably on a flat surface such as a table or desk,
- a pivoting frame on said base comprising an upper arm extending on said pivoting frame and having a transverse attaching plate formed integrally therewith, said plate having a pair of vertical adjusting slots therein,
- an upper plate having spaced mounting sleeves attached thereto,
- a removable upper model frame having respective terminal ends insertible into a respective sleeve,
- a pressure means for holding said removable upper model frame in place,
- attaching means on said plate to provide the vertical adjustment for the articulation of the upper and lower model thru the vertical movement of only the top,
- a lower bracket comprising a lower model frame and a lower plate,
- a pair of spaced mounting sleeves on said lower plate,
- said lower model frame having respective terminal ends insertible in the respective openings in the mounting sleeves and adjustable pressure means for holding said lower model frame in place.
In a dental articulator device for holding an upper model and a lower model representing the upper teeth and lower teeth:
- a base,
- a movable upper frame on said base for supporting the upper model,
- a pair of spaced frame retaining portions on said movable upper frame and each having an opening extending therethrough,
- an upper model frame support having terminal end portions respectively removably inserted in said openings whereby said model frame support may be permanently attached to the upper model such as by plaster,
- pressure means for removably locking said terminal ends of said upper model frame on said base whereby said upper model frame may be adjusted.
In a dental articulator device for holding an upper model and a lower model representing upper teeth and the lower teeth:
- a base, a pivoting frame mounted on said base for supporting the upper model thereon, an upper mounting support for said upper model, means for removably mounting said upper mounting support on said pivoting frame whereby the upper mounting support may be removed and repositioned on the same or another identical articulator device, means for vertically adjusting said upper mounting support with respect to said base whereby said upper model may be vertically adjusted, means for adjusting and setting the angle of said pivoting frame on said base, a lower mounting support on said base for said lower model, means for removably mounting said lower mounting support on said base whereby said lower model may be removed and repositioned on the same or another identical articulator device, and means for horizontally adjusting said lower mounting support with respect to said base.
In a dental articulator device for holding an upper model and a lower model representing upper teeth and the lower teeth:
- a base, a pivoting frame mounted on said base and said pivoting frame comprising an upper arm and a lower arm, said lower arm being engageable with said base, a pivot pin on said pivoting frame extending from opposite sides thereof, said pivot pin being mounted on said base extending transversely thereacross, a guide member on said pivot pin, a groove on said base in which said guide member is mounted to align said pivoting frame on said base, a mounting pin on said base engageable with said pivoting frame, spring means interposed between said mounting pin and said pivoting frame, an upper portion on said pivoting frame, a pair of vertical slots in said upper portion, a mounting plate having a pair of spaced openings therein, an upper mounting support for said upper model having terminal ends inserted in said spaced openings, a lower mounting plate, a horizontal slot in said base, adjustment means such as a bolt for mounting said lower mounting plate in said slot, a pair of spaced openings in said lower mounting plate, a lower mounting support for said lower model having terminal ends inserted in the spaced openings, and pressure means such as a bolt for adjustably mounting said lower mounting plate in said slot.
