Treatment of severely worn teeth
(page 2)

After it is determined that an increase in the facial height can be accomplished, wax is added to the plaster casts and carved to simulate what the teeth should look like if no wear had occurred. This procedure is called a diagnostic wax-up and is a critical stage of the diagnostic and treatment process. This wax-up acts as the guide to the dentist for all susequent procedures and allows the patient to get an idea of what the final result will look like prior to any irreversible procedures being performed.

Severely worn teeth.

Diagnostic cast.

An impression is made of the teeth and plaster is poured into it to produce a cast.

The front teeth have been reshaped by adding a tooth colored wax to give an idea of the final esthetic result. The back teeth are commonly waxed with a darker color wax to allow better visualization of the anatomy of the chewing surfaces to the dentist and the laboratory technician.

Finished case.

Note how closely the final result resembles the above wax-up.

Plastic template.

Upon completion of the wax-up, a clear plastic template of the same shape as the wax-up is made. This template serves as an aid to the dentist during the preparation of the teeth, fabrication of temporary crowns, and the during the construction of the final crowns or veneers.

The amount of anticipated lenghtening of the teeth is clearly seen. (Space between the two arrows.
