Bite Registration Wax
Carmel Bite Registration Wax Sheets are used for accurate impressions and bites, and resists distortion and deformation. Available in sheets that can be cut and molded into desired shapes.
How to Register Central Occlusion (CO)
Beauty Pink and Light Blue
1) Take the previously plasticized wax from the thermal bath 53ºC (127.4ºF) and mold it with your fingers to the surface of the upper teeth, just enough to keep it in position.
2) Ask the patient to close down tightly until the teeth surfaces are felt to be in contact. Cool the wax with the air syringe.
3) Before the wax completely hardens, remove it from the mouth and trim it with scissors. Trim everything that exceeds in the lateral and posterior sections.
4) Put the wax back in the mouth and verify that the patient bites down the same as they would without the wax.
5) Cool the wax with an air syringe. Remove it and leave it in the rubber cup with cold (refrigerated) water.
6) Put the hardened wax back into the mouth and repeat step 4. This last extra step is important since we have been able to verify that of all the steps involved in assembling models, the one in which the most errors are made is in the CO register. Finally, store the wax in a safe place, as it will later be used to measure the discrepancy between CO and RC, through a procedure known as MCD (Measures Condyle Displacement). This allows the condylar position to be recorded at the time the teeth are in maximum intercuspation.
Possible solutions include:
A) Place the wax on the upper plaster model and use a scalpel to scrape away the parts that contact the palate. Note that if there is a lot of wax to shave off, the register could thin excessively, and can fracture.
B) Repeat the registration with new wax while taking care to heat only the edges where the indentations will be made in the thermal bath. The tongue's influence diminishes as the central portion becomes rigid.
C) Finally, we advise not to mention the tongue to the patient. In some cases, by trying to cooperate, they will move their tongue even more, distorting our register.
