Step 1 Initial Layer of Wax
|
|
|
With the prepared tooth in your hand (not screwed into the typodont), apply a thin layer of BLUE wax to the preparation. The wax should be of even thickness (approximately 0.5mm) and cover the labial surface of the crown and the incisal portion of the preparation (prepared tooth surface). The wax should go to and slightly beyond the cavosurface margin of the preparation initially. Remove gross excess wax now. The final finishing and refinement of the margins will be managed at a later stage in the waxing procedure. The margins will be sealed and properly contoured using the beavertail portion of the BEAVERTAIL/ACORN burnisher in one of the last steps of the procedure. Use the PKT1 instrument to apply the wax. There should be no voids in the wax.

Step 2 Establishing the Incisal Ridge
|
|
|
Screw the prepared tooth into the typodont. Using a PKT1 and GREEN wax, establish the incisal ridge. Evaluate amount and location of wax from the labial, lingual and incisal views. Adjustments may be made with the tooth in or out of the typodont. The goal is to add the correct amount of wax in the correct location using your wax instruments. Minimal carving should be required. Evaluate amount and location of wax from the labial, lingual and incisal views.

Step 3 Establishing the Contour Bars
|
|
|
Remove the tooth from the typodont to begin this step. Using a PKT1 and RED wax, establish the mesiolabial contour bar, middle labial contour bar and the distolabial contour bar. Only the labial and incisal of this tooth has been reduced. Evaluate amount and location of wax from the labial and incisal views. Assess the contact after adding the incisal ridge. Carefully close the typodont. If the contact is heavy, heat up the wax to achieve an ideal location, size and magnitude of the contact. See the final picture for the location and size of the contacts.

Fill in the remaining missing tooth structure using the PKT1 or PKT2 instruments using WHITE wax. Most of this step can be completed with the tooth out of the typodont. In this preparation, the contact has not been touched. Therefore, only the labial and incisal surfaces have been restored with wax. Use the BEAVERTAIL/ACORN burnisher, the CD 4/5 (discoid cleoid) carver to complete the final contour and finish of the wax-added exercise. Use a piece of nylon stocking or pantyhose to complete the finish. Screw the tooth back into the typodont and evaluate. Make sure margins are sealed, contour is ideal, and the surface is smooth.

Contact position and size
The distal marginal ridge of the maxillary left central incisor and the mesial marginal ridge of the maxillary lateral incisor are in contact with the incisal ridge of the mandibular left lateral incisor in maximum intercuspation.
