Occlusion of artificial teeth in complete dentures: population-based analysis.

Unlabelled: Occlusion is a central aspect of all prosthetic restorations, including complete dentures. Within the follow-up (SHIP 1) of the regional population-based "Study of Health in Pomerania" (SHIP), a number of 3300 study participants were examined concerning the occlusion of artificial teeth in purely mucosa and non-implant-borne complete dentures. These subjects were representative of the population.

Occlusion of artificial teeth in partial dentures in the "chewing center"--first exploratory population-based evaluations.

Occlusal performance is a substantial determinant of the quality of dental prosthetic restorations. In the follow-up (SHIP 1) to the Study of Health in Pomerania (SHIP), a representative population of 3300 subjects was studied in the first exploratory evaluation of the occlusion of artificial teeth in the chewing center (first molar region) of partial dentures. A digital analysis of interocclusal records of habitual intercuspation position (ICP) was performed using the Greifswald Digital Analyzing System (GEDAS), a software package that identifies contact points as transparent areas.

Variability of closing movements, dynamic occlusion, and occlusal contact patterns during mastication.

Virtual articulation makes it possible to overcome the limitations of mechanical articulation. Novel visualization techniques have great advantages. In this study, the occlusal surfaces of the upper and lower teeth were digitized with a 3D scanner, and real functional movements of the mandible were recorded using the Jaw Motion Analyzer (JMA), an ultrasonic measurement system.

GEDAS II--new possibilities in digital contact point analysis.

The following article describes a method for the clinical depiction and documentation of the strength, extent, and location of occlusal contact areas on the basis of digitized bite records. Bite records made of low-viscosity, addition-cured silicone in centric occlusion are digitized in a document scanner using incident and transmitted light scanning. Layer thicknesses < 20 microm were interpreted as occlusal contacts and classified as belonging to the anatomical structures of the occlusal surfaces.
