V. Read and translate the text, entitle it. Say if the following statements are true or false, correct the false statements to make them true.

Articulators are used for application processes indirectly, outside the patient’s mouth. This is very economic and time saving because many procedures can’t be done inside the patient’s mouth. Benefits of articulators are:

• Patient’s cooperation is not a factor: we work on them while the patient is not there. So we are not affected by the patient’s status.

• It provides a constant centric relation and proper positioning of the TMJ.

• We can see the occlusion completely.

• We can examine the lingual areas.

• It is a time saver.

Different articulator types are used depending on the type of restoration being fabricated as well as personal preference of the clinician or dental technician.

Adjustable dental articulators enable the technician to individually set the joint angles are necessary in a dental lab to fabricate prosthodontic and orthodontic restorations and appliances. An adjustable dental articulators enable the technician to individually set the joint angles to exactly match patient measurements to get the perfect fit.

A non-adjustable articulator allows fixation of casts of the maxillary and mandibular teeth, showing recorded positions of the mandible in relation to the maxilla. These measurements assist in the fabrication of various dental appliances. Non-adjustable articulators only open and close in a fixed horizontal axis, they can simulate lateral and protrusive jaw movement.

1. Articulators are used for application processes inside the patient’s mouth.

2. Using articulators is time saving.

3. We can work on articulators only with patient’s presence.

4. It’s used to check the bite.

5. Dental technicians have a variety of articulators to choose from.

6. Non- adjustable dental articulators enable the technician to individually set the joint angles.

7. Adjustable dental articulators can simulate lateral and protrusive jaw movement.
