Wax Try-in

Dentist markings on the bite registration block 

Midline, middle of the face

This line is not necessarily identical to the upper and lower lip tendons or the midline of the model.

Canine line

This determines the width of the upper anterior, and where the tips of the canines are to be positioned. Also, their positioning can be determined on the basis of the corners of the mouth or a vertical extension of the outer nasal wings.

Smile line

This is decisive for the length of the upper anterior. The tooth necks should normally be above this line.

Occlusal plane

It follows the upper edge of the lower wax bite rim, i.e.: between the lower incisal edges in the anterior area and the distobuccal cusps of the lower second molar. It intersects the midline which is the fixpoint for the incisal pin and runs parallel with Camper`s plane.
