When fitting a patient with a full denture, the Fox’s Bite Plane establishes the orientation of the occlusal plane in an anteroposterior direction (Spee curve) and also the frontal plane with the interpupillary line. It ensures the patient ends up with an even set of dentures that are going to have a more reliable occlusal relationship.

What’s good about it

When working with a patient that needs full dentures, you don’t have any reference for ascertaining the occlusal plane. The Fox’s Bite Plane gives you the correct orientation and level. It prevents larger problems in the future when the patient starts to wear the denture.

When the patient comes in to try in the wax, it’s still possible to make some adjustments before the setting of acrylic teeth. Sometimes I use a pencil and draw a line from the lateral side of the nose to the ear to make an orientation of the Frankfurt plane measurement. When they hold the Fox Bite Plane in their mouth, there are parallel wings extending from both sides of the unit. This gives you an indication of any discrepancies and you can add or reduce the wax. It is obviously much better to make the adjustments at this point rather than when the acrylic teeth are set or even when the denture is made.

This tool helps create a much more reliable denture for the patient. Patients actually seem to enjoy the process as they know it’s going to provide the best result for them.

It’s a very cheap tool that is essential when working with full dentures or full rehabilitation.

What’s not so good

This tool is easy to use, does what it’s supposed to do and gives a good result. I hope that it never undergoes any changes.
