Articulator—semiadjustable, arcon with lower and upper parts that could be detached from one another or interconnected, with two mechanical joints. An upper horizontal shoulder (5) is fixed to an elevator (4), said elevator (4) is connected to an upper vertical body (11) and can move vertically to adjust the vertical position. A lower vertical body (10) is fixed to the base (1) and holds an axis with two joint heads (14). The upper vertical body (11) is pivotably connected to the lower vertical body (10) through the two joint heads (14), the distance between the joint heads can vary due to an elastic element (18), thus reproducing the lateral shift. The articulation between the vertical bodies (11 and 10) can be locked and unlocked via an elbow shaped piece (13). The articulator lower part has an incisive platform (8) with a position angle that could be adapted. |

1. Articulator—semiadjustable, arcon, consisting of lower 21 and upper 22 parts that could be detached from each other or interconnected with two mechanical joints, as the lower part 21 consists of base 1, over which working plate 6 is located, with incisive platform 8 assembled at the front of it, and at the rear the base is immovably connected to vertical body 10, to which horizontal axis is fixed with joint heads 14, to which two bodies of the joint cavities are adapted 3, connected in the middle with plank 2, which is immovably connected to the upper vertical body 11, connected at the front to upper horizontal shoulder 5, under which the magnetically connected working plate 6 is located with incisive pin 7 assembled at the front, propping up the incisive platform 8 with the following features: the upper horizontal shoulder 5 is immovably connected to elevator 4 that is fixed at the front of the upper vertical body 11 and is able of moving up and down, until propping up the upper working model and connecting to it, as the upper vertical body 11 and vertical body 10, which is immovably connected to the base 1 could be blocked and de-blocked, via elbow 13, which ensures continuous inter-parallel location of the base 1 and the upper horizontal shoulder 5 during the process of operating the articulator. |
