Definitions

• the invention relates to an occlusionoma according to the preamble of claim 1.
• the local joint allows an adaptation of the bite fork about a horizontal axis which extends perpendicular to the condylar axis, although no detection of the angular position is provided.
• reference bows are still used today which are associated with bifurcated forks and are termed a bite fork set, either via a joint or in one piece, with the bite fork sets often having a reduced length.
• the bite fork sets are often formed of metal strips that extend horizontally. It is at the discretion of the dentist or possibly the dental technician, whether he wants to bend the metal strip, if necessary, to his liking, or wants to "extend" for example by means of a piece of wood until the condyle joint is reached. While such solutions are inexpensive, they are ergonomic and unsatisfactory in terms of accuracy of fit.
• Campersche level is known to pass through the Subnasaltician and Tragus. In many cases, it is considered to be parallel to the occlusal plane, although, upon closer inspection, it is also possible to detect angular deviations that vary from patient to patient.
• a wax template is used, which is set to an average value as an empirical value, for which an occlusionoma can be used.
• auxiliary devices for articulators have been proposed which have scales to account for any deviations from common values.
• auxiliary stirrups are also used.
