Where to position the upper incisal plane

The incisal plane (occlusal plane viewed from the front) of the upper artificial teeth generally looks correct when parallel with the interpupillary line.

If the patient’s eye position is asymmetric lining up the incisal plane with the interpupillary line may look wrong and experimentation is required.

The incisal plane shown in a photograph of the patient when they had natural teeth can be mimicked when trimming the wax rim. The rim prescribes the position of the denture teeth.

In the accompanying photograph the incsial plane of the patient’s natural teeth was NOT parallel to the interpupillary line. We copied this in the complete upper denture at her request. The patient guides this process and is the final arbiter.
