according to Prof. Dr. Dr. Arnim Godt & Daniel Schweizer, Certified Dental Technician
Intraoral diagnostic set-up for neurocentric registration.The wax spacer is a physiological registration for determining predefined bite heights. The wax spacer precisely measures the exact position of the lower jaw to the upper jaw. The bite-resistant insert (spacer) incorporated in the wax wall ensures that the jaw relation is determined which includes the desired bite increase and a constant interocclusal distance. Therefore, the patient himself determines the positional relationship in the transverse and sagittal relation of both jaws with the intended bite height. During bite registration of dentulous jaws and prosthetic restorations the spacer ensures that the patient cannot bite through to the final occlusion, but only until the built-in stop (spacer). A cusp-to-cusp contact is therefore prevented.
-
The wax spacer determines a defined bite raise without complex measurement of the
temporomandibular joint rotation.
-
The wax spacer is available in different thicknesses (colour-coded) for different heights.
Thus, the exact positioning of the lower jaw can be ensured in the therapeutic position.
-
The wax spacer is a reliable physiological bite registration to register the position of the
temporomandibular joint in different distances between the rows of teeth to each other.
