What are Pressure Points in Dentistry?

Watch Dental Video about Pressure Points

In dentistry, the term “pressure point” refers to prosthesis pressure points.

If the base of a prosthesis doesn’t fit the jaw precisely or if the prosthesis was not well executed, this may lead to prosthesis pressure points.

In the video "Pressure Points" you see such a pressure point – in this case, the patient recently had his remaining teeth extracted due to damage to his periodontium.

Immediately after such tooth extractions, the alveolar ridge undergoes serious restructuring, which in turn leads to a poorly-fitting prosthesis and the development of pressure points. Anyone who has ever experienced a pressure point knows how painful these small wounds can be.

The prosthesis is either cut at that particular point or is relined. Furthermore, the dentist checks whether it is a static or dynamic pressure point. If it’s a static pressure point, the prosthesis has a good hold and only one part of the jaw is being stressed by the uneven support. By leveling the base of the prosthesis, the pressure point is removed.

Pressure Points

In a dynamic pressure point, the prosthesis does not have a good hold and the occlusion is often not correct. Because of this, the prosthesis moves around and rubs against the oral mucosa and pressure points develop. Removing dynamic pressure points makes no sense because the pressure point reoccurs later at a different location. In this case, the prosthesis has to be replaced or at least relined. Oftentimes, prostheses with a soft prosthesis base material, called a soft relining, are offered. Such prostheses are well-suited to condition the mucous membrane when the prosthesis is initially settling in.

However, the soft relining should be exchanged for a hard one as quickly as possible, because the soft plastic compounds aren’t good for the oral mucosa. Finally, it should be pointed out that a malignant tumor of the oral mucosa can begin like a pressure point. If the assumed pressure point doesn’t heal despite cutting and/or replacement of the prosthesis, then a biopsy of the oral mucosa should be performed in a specialized hospital in order to exclude the possibility of a tumor.
