Teeth under pressure: what grinders should consider when restoring their dentures

According to estimates, every fifth person in Germany suffers from bruxism, the subconscious and usually nightly pressing of the upper and lower jaw. "Enormous forces act on both the natural tooth enamel and the dentures," emphasizes Dr. Christoph Sliwowski, Head of the Dental Implant Clinic Düsseldorf at St. Vinzenz Hospital.

"Those affected who need dentures should therefore always use materials that can withstand or at least reduce this involuntary biting pressure." Contrary to what many people think, all-ceramic is not the first choice for patients who have gnashed teeth.

Reduce cracks and cracks

When it comes to aesthetics, compatibility and stability, ceramics, i.e. zirconium oxide, are the first choice for dentures. But it is precisely because of this pronounced hardness that cracks and cracks often occur in the material under extreme pressure loads, such as those caused by crunching. Repairs then usually involve a high financial outlay.

In some cases, the dentures even have to be completely removed and made again. And the opposite natural tooth surfaces are also damaged when they are pressed together with ceramic crowns: “Our natural tooth enamel is softer than zirconium oxide. So if the crown and healthy tooth meet, the latter wears out much faster, ”explains Dr. Sliwowski. He therefore advises those affected to use more flexible materials such as plastic or metal alloys made of gold.

Protect healthy tooth enamel

For crowns for patients suffering from bruxism, we recommend either a metallic restoration without a ceramic coating or the alternative made of plastic. Both materials are considered flexible and thus reduce the risk of damage to natural tooth enamel. “We prefer a supply of plastic. One of the advantages of this is that it resembles the natural tooth color, ”says Dr. Sliwowski.

“In particular, front teeth can be easily supplied with veneers made of plastic. For prostheses and partial prostheses, grinders should also use this soft alternative. ” In order to protect both the dentures and the natural enamel when grinding, many sufferers also wear special plastic splints at night.
