An Articulator is a mechanical device used in dentistry Semi-adjustable, fully adjustable, Anatomical Articulator.
An articulator helpful in planning and predicting patients jaw relation. Patient's number of visit reduces.
But still errors are like slight alterations in jaw relation due to lack of exact anatomy.

1. THE NEED OF ARTICULATORS
IN DENTAL RESTORATION
PROCESS
2. An articulator is a
mechanical device used
in dentistry to which
casts of the maxillary
(upper) and mandibular
(lower) teeth are fixed,
reproducing recorded
positions of the
mandible in relation to
the maxilla.
4. Types of Articulators
Semi-adjustable articulator
As the name suggests, it is
adjustable partially in
one or more areas but
not all of the following
areas: condylar angle,
Bennett side-shift, incisal
and cuspid guidance, and
shape of the glenoid
fossae
5. Fully Adjustable
Articulator
It is completely
adjustable and
capable of
reproducing more
than one movement
including extrusive
and protrusive
movements.
6. Anatomical articulator
It helps the dentists to
create lower jaw
movement that the
patient experiences
during his normal
chewing.
7. • Disposable articulators
There are two types of disposable articulators
Stone base - The model of
patient’s lower and upper jaw
mounted on a stone base are
articulated. It requires making
two pours using a rubber mold.
Single-pour – The operator casts
the jaw impression directly on a
plastic base. There is no need of
stone base
8. PURPOSE OF USING ARTICULATORS
• For arrangement of teeth setting in case
of removable and complete dentures.
• Inacting of jaw movements like
opening and closing
• Fabricating occlusal surface required for
restorative purpose.
9. • For initial and overall treatment
planning of the procedure.
• To help in modifying restorations
• For predicting the state of occlusion
• For teaching jaw relation to students
11. WHY DENTISTS SHOULD CONSIDER
USING ARTICULATORS
• As articulators can be helpful in planning the
procedure and predicting patients jaw
relation, it often reduces visits made by
patients and decrease the procedural time.
• Many of the problems faced during the visit
like controlling tongue mobility of the patient,
retraction of cheek, saliva overflow are
completely bypassed through articulators.
12. • Prosthetic work can be done in absence
of patient.
• Sometimes , visualizing the lingual side
is not easy in a patient, but this
situation can be coped up with the use
of articulators.
• For modification and correction of
restorations.
13. HOW TO CHOOSE FOR AN IDEAL
ARTICULATOR
• Opening and closing in hinge
movement.
• The parts that have to move should be
in a moving motion and the parts that
do not require to move should be
stable.
14. • It should be adaptable to a face bow
transfer record
• It should be able to position the cast in
correct vertical and horizontal
relationships.
• Lateral movements and protrusive
movements should be taken into
consideration.
• Positioning of incisal pin should be
accurate.
16. • Being a mechanical model, errors are
do subjected to occur due to wear and
fatigue.
• As the exact anatomy of oral cavity is
missing, there may be slight alterations
in jaw relation.
• Articulators cannot mimic complete
functional movements.
