3.1.2 - Articulator Model A7 Plus
To facilitate the mounting of the casts, adjust the Condylar Guides angles at 30º and the Bennet
at 0º (fig. 29 and 30). Then push back the upper part of the central lock until feel the “click”
(locked position fig. 31).
PS.: In order to make sure that the Articulator A7 Plus is totally locked at the centric position,
check if the 2 locks (left and right) are at the locked position.

3.1.3 - Articulator Model A7 Fix
Aiming as main characteristic simplicity and easiness to work, the A7 Fix Articulator was
developed with the Bennet and Condyle angles fixed at the average of 15° and 30°,
respectively. The intercondilar distance was also fixed at the average of 110 mm. Therefore,
this model does not require preliminary adjustments for these components, such as the other
models previously mentioned. In order to lock the Articulator A7 Fix in the centric position, there
is an innovative system with two lateral pins, denominated: “centric lock pin”. This pin has 3
main positions: first position - totally closed (locks the articulator in the centric position - picture
32); second position - intermediate (releases the articulation movements - picture 33) and third
position (allows to remove the upper from the lower frame - picture 34).
