There are 3 types of adjustable articulators:
i, Non adjustable articulators - makes all the movements of the tmj, but all the movements are at fixed averages.
- example ; Hanua mate
- the simple hinge would also be an example - the only movement this articulator can simulate is an opening and closing action
i.e. vertical
ii, Semi adjustable articulator - these articulators are more accurate tthan the non adjustable articulators
- this articulator is set to the bite registration recorded by the dentist - even with this registration the articulator will not make or simulate the anitomical curvature of the tmj, nor are these movements exact.
-example; Hanau model H
- is able to move in transverse, vertical, saggital and horizontal planes
iii, Fully adjustable articulator - able to simulate the movements of the tmj more accurately than the other articulators
- bite registrations are constructed by means of a pantograph, which reconstructs the condylar and Bennett angles.
- this represents the exact anatomical movement of the tmj.
- more able to simulate the patient's anatomical conditions intransverse, vertical saggital and horizontal planes to a greater degree of accuracy than is the semi-adjustable articulator.
- example; Denar Mk II and the Pantograph
