Occlusion and the potential effects of
occlusal interferences on patients
The occlusion (any contact between maxillary teeth and mandibular teeth) is exposed to constant
change. Every restoration, extraction (teeth migration), prosthetic care and oral surgery always
implies a change in occlusal proportions. Constant monitoring of the latter and an understanding
of all related factors provide the basis for good dentistry.

physiologically unsound position. This new bite of
convenience causes irregular muscle activity which can
eventually lead to temporomandibular joint pain and
myalgia. Frequent headaches as well as bruxism and
grinding may ensue. If the symptoms persist long-term, it
becomes increasingly difficult to diagnose the condition.
The source of the problem, i.e. the incorrect adjustment of the inserted bridge, may even be
masked. Ultimately, the dysfunction can be traced back to the dentist.

Accurate detection of High Spots
Only ultra-thin test films, such as those available in our product range, are frequently used to test
the occlusion. It is generally believed that grinding should only be carried out with ultra-thin test
films which, in theory, can be recommended, but in practice is extremely difficult and timeconsuming.
Occlusal contacts are very often no bigger than the size of a needle point and
therefore should be represented with precise test materials which leave a clearly delineated color
transfer. For example, on an articulator model, clear reflection using a test film on dry occlusal
surfaces poses no problem. But as soon as the occlusal surfaces are moistened with saliva, the
reflection of films, especially on ceramics or polished metal masticatory surfaces, can hardly be
seen. This explains why many dentists assume that there are no high spots since nothing is visible.
The color transfer of articulating films on moist surfaces is inadequate on chemical and physical
grounds. The color coating of all articulating test films and even of some of the articulating papers
consists of wax, oil and pigment, a hydrophobic mixture which repels saliva (hydrophilic)
consisting mainly of water.
