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.
Technique for Hard Bite Registration Wax:
Registration of Centric Occlusion (CO) Centric Occlusion (CO) is the interocclusal relationship in which the greatest number of contact points are established, independent of condylar position. It is also known as Habitual Occlusion (HO), Maximum Intercuspation
(MIC) or Intercuspal Position (ICP). Unlike Centric Relation (CR), which represents an articular relation, the OC corresponds to an exclusively dental relationship. Extra hard wax has thermoplastic properties, it plasticizes at 53ºC (127.4ºF), acquiring a softer consistency without losing the original properties suitable for bite registration. This allows for a very good cuspidic impression. Once cooled, the wax regains its hardness such that it fractures before deforming.
Prepare each wax sheet by folding it in half in the upper dental arch, thus obtaining a wax cookie, which is 2 wax sheets thick. The wax will then be individualized for each patient with the help of the upper model, covering the occlusal face and incisal edges of all teeth.
How to Register Central Occlusion (CO)
1) Take the previously plasticized wax from the thermal bath 53ºC (127.4ºF) and adapt it with your fingers to the surface of the upper teeth, just enough to keep it in position.
2) Ask the patient to occlude tightly in their usual closed position, until the opposing occlusal 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 sectors.
4) Put the wax back in the mouth and verify that the patient occludes 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 OC register. Finally, store the wax in a safe place, as it will later be used to measure the discrepancy between OC 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.
THE MOST COMMON ERRORS IN CO REGISTRY
Some patients report having “several bites” and are not clear which of them is more comfortable, so they can occlude in different positions at the time of the OC registration. The solution is to teach the patient to define a single occlusion that is comfortable for them, and which represents the best fit between the upper and lower teeth. Once the patient is clear about their OC and is able to repeat it, proceed to record it. For greater security, we suggest always doing the OC registration before the CR registration, because in some cases (to cooperate), the patient will unconsciously try to repeat the CR position. If the wax temperature is not adequate, it will not be possible to take a clear record of the indentations. However, it is sometimes difficult to maintain the water temperature at 53ºC, due to the fact that the thermal bath tends to be frequently deregulated. This yields a very soft wax which loses its shine and becomes opaque. Losing part of its properties makes it difficult to properly adapt the wax to the plaster models, which in some cases makes it difficult to register the CPI. That is why it is essential to work with a perfectly calibrated thermal bath.
Wax contact with the palate
Despite the wax being at the right temperature, in some patients the tongue tends to curve the wax, bringing it closer to the palate, and even coming into contact with it. In plaster models, the contact of the hardened wax with the "palatal mucosa" of the cast prevents the correct adaptation of the wax to the teeth, and consequently renders the Central Occlusion registration useless. The possible solutions to this problem include:
A) Place the wax on the upper plaster model and abrade with a scalpel the parts that contact the palate. This solution is not always feasible, since if there is a lot of wax to wear off, the register thins excessively, sometimes even fracturing.
B) Repeat the registration with a new wax, while taking care to heat only the edges where the indentations will be made in the thermal bath. As the central portion becomes more rigid, the influence of the tongue is attenuated.
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.
