Articulators are hinged frames that mimic the movement of the human jaw. There are many types with varying forms of adjustment. Aside to each image below is a brief description, a more descriptive document has been attached here: Articulators (pdf).
The Mortimer
Over sixty years old but still in use today!.
Early Plasterless
A plasterless articulator similar to the Mortimer.
Galetti
A plasterless articulator. A lab favourite introduced in the early 1980's. Used for quick reference. Has 3 point guidance.
Unident ASA
The current basic lab articulator. Has average angles and 3 point guidance. An industry standard.
Dinar
The most widely used "artic" in the UK. An industry standard in both semi and fully adjustable form. Widely used in Crown and Bridge work.
Ivoclar Stratos
One of the top of the range artics used in the UK. Semi adjustable, it handles particularly well. It is especially suited to modern prosthetic techniques.
Kavo
Arguably the finest and most versatile Articulator available. It is very expensive and not widely used, but is in our opinion - top of the class.
