Bite Templates in Dentistry

 

Watch Dental Video about Bite Template

Bite templates are used in order to determine the jaw position/relation in people without teeth or with severely reduced teeth.

The position of the lower jaw is not constant. An example of this phenomenon is when you wake up in the morning and your two jaws don’t fit as well with each other as they did previous day. It’s only after a few chewing motions that our jaw musculature once again finds the proper jaw position by means of the sensitive pressure receptors in the periodontium. The day can begin!

More on that in the video Bite Template.

Thus, the position of our lower jaw is not constant and must be relearned again and again. If the lower jaw is “forced” into an unfavorable position, e.g., due to a bad dental prosthesis, this may cause facial, jaw joint pain, or even headaches.

In cases of toothless individuals or in those with very few teeth, the technician needs a reference point that shows how the jaws generally position/relate with each other; this reference point is provided by the bite template.

In the video you see how such a bite template is produced with the aid of a plaster model. The dentist first takes impressions of both jaws. The dentist provides the technician with a rough positioning/relation of the jaws by means of a so-called squeezer, a silicone compound that is placed between both jaws and then hardens. Once hardened, the impressions and the squeezer are given to the technician, who can now produce plaster models, position them roughly towards each other, and ultimately, produce a proper bite template.

As soon as the dentist receives the bite templates from the technician, the patient visits the dentist a second time so that his bite can be taken. The dentist places the bite template in the patient’s mouth; bite templates can be produced for both lower and upper jaws, depending on the remaining teeth. The patient bites carefully, thus creating impressions in the wax wall of the bite template. The dental technician is now able to position the plaster models in a definite relationship to each other.

Now the prosthesis can be produced in the articulator. In most cases, a so-called wax set-up is created, meaning that the teeth in the prosthesis are not yet mounted in plastic, but in wax. When the patient tries on the the wax set-up, the dentist checks whether the data transmitted by the bite template was correct. The patient must feel comfortable with his teeth; thanks to the wax set-up, the teeth can still be moved slightly and the bite can be corrected. It’s only when everything fits perfectly that the prosthesis is considered complete.
