Diagnosis impression
İmp. Made for purpose of diagnoses
For construction of Special tray
Primary imp.
For fabrication of custom tray, border molding and making wash impresiion
Secondary impression
İt is plaster reproduction of teeth and their surrounding soft tissue that provide a reasonable
representation
of occlussion of patient
Study models
Simple appliances, accept single static recording(hinge mov.)
Class 1articulator
Gariot
Class1
Vertical horizontal mov. Not oriented to tmj
Art. Adı
Class2
bonwill, gysi simplex
Class2
Which articulator can orient models according to joint and simulate condyle paths
Class 3
According to joint and 3d dynamic recording
Class4 denar,tmj
Only correct position centric occlusion
Eccentric mov.
Non adjustable art. Class1
can duplicate not only the centric occlusion but also the eccentric movements of the patient very similarly
Semi-adjustable articulators
Condylar element is attached to upper
member of the articulator and the condylar
guidance (articular eminence) is attached to
the lower member
Only straightcondylar guidance
