The total surface and number of occlusal contacts in the static and dynamic occlusion of the teeth. Development of the methods.

For reasons of different data in literature on occlusal parameters and their metric registration at the beginning of the eighties two methods, independent from each other, were developed to registrate the total occlusal contact area and the number of occlusal surfaces of contact on dental casts--the capacity measuring method and the quasi-planimetry method. The results obtained independently from each other show a high degree of correspondence. Because of its easy handling the method of quasi-planimetry was further developed and used for direct analysis of enorally obtained wafers of different characteristics. The total surface of occlusal contacts in the static occlusion ran up to 4-6 mm2, and the number of stops to 19-30. The method of qualitative and quantitative analysis of occlusal parameters is improved with a modern system of digital analysis. The results obtained up to now admit the conclusion that the occlusion of the teeth represents an individual condition of high variability.
