Abstract
The invention relates to an improved articulator (1) to realize gypsum models comprising a fixed lower arm (2) and an articulated upper arm (3), a respective impression bearing plate (5, 6) being provided on said lower (2) and upper (3) arms, removably coupled with the same, said articulator (1) being characterized in that the coupling between each arm (2, 3) and the respective plate (5, 6) is realized by means (9, 10; 12, 13) allowing the adjustment of the position of the plate (6, 6) with respect to the relevant arm (2, 3).
Claims17
Improved articulator to realise gypsum models comprising a fixed lower arm and an articulated upper arm, a respective impression bearing plate being provided on said lower and upper arms, removably coupled with the same, said articulator being characterised in that the coupling between each arm and the respective plate is realised by means allowing the adjustment of the position of the plate with respect to the relevant arm, and characterised in that said means for the adjustment of the position of the plate with respect to the relevant arm are comprised of a plurality of ribs and of a plurality of corresponding grooves, realised on the lower or upper arm and on the respective plate, or vice versa, and a plurality of holes being provided on the plate with respect to the relevant arm for the removable coupling with the relevant arm.
An articulator for use in dental model formation, comprising:
- a lower arm;
- an upper arm, articulable with respect to said lower arm;
- an upper impression plate;
- a first coupling means for removably coupling said upper impression plate with said upper arm;
- a lower impression plate;
- a second coupling means for removably coupling said lower impression plate with said lower arm;
- said first coupling means including first adjustment means for positional adjustment of the upper impression plate with respect to said upper arm, said first adjustment means including an engageable projection and projection reception combination provided on the upper arm and upper plate for mutual adjustable engagement of the upper impression plate with respect to said upper arm, and said first coupling means including a plurality of holes in said upper impression plate for use in releasably coupling, in different positions, said upper impression plate with said upper arm;
- said second coupling means including second adjustment means for positional adjustment of the lower impression plate with respect to said lower arm, said second adjustment means including an engageable projection and projection reception combination provided on the lower arm and lower plate for mutual adjustable engagement of the lower impression plate with respect to said lower arm, and said second coupling means including a plurality of holes in said lower impression plate for use in releasably coupling, in different positions, said lower impression plate with said lower arm.
