  • Title: Do occlusal contact detection products alter the occlusion?
    Author: Helms RB, Katona TR, Eckert GJ.
    Journal: J Oral Rehabil; 2012 May; 39(5):357-63. PubMed ID: 22211464.
    Abstract:
    Clinicians rely on occlusal contact detection products to identify high contacts and to equilibrate occlusions. Concerns about these products have stimulated numerous investigations into marking reproducibility, accuracy and interpretation, but none have looked at their effects on the occlusion itself. The aim of this study was to assess whether these products alter the occlusion that they purport to measure by determining whether there are differences in the forces and moments experienced by occluding teeth with and without their presence. A matched pair of IPN Portrait 33° molar denture teeth was placed into occlusion with the mandibular tooth supported by a load sensor and the maxillary tooth mounted onto a vertically sliding assembly with a total weight of 15·1N. The three-dimensional force and moment components on the mandibular tooth were measured when the teeth were in direct crown-crown contact (control) and with the products in place. All six products, (Accufilm I, Accufilm II, Hanel Articulating Silk, Rudischhauser Thick and Thin, and T-scan) showed significant (P<0·05) differences in forces and moments from control.
