Abstract

The following considerations refer to the path of such movements of the mandible, at which execution the occlusal surfaces of the rows of teeth in contact or pressure, maybe with a thin layer of food between, are shifting along each other, also movements, which can be executed as a lateral version and sagittal shift of the mandible isolated or in connection with biting off it as happens often as a mandibular backward slide. The course of this movement, which serve specifically for the grinding of the food, depends not only on the mechanical aspect of the temporo-mandibular joints as such properly, but will be determined very strongly by the configuration of the occlusal surfaces of the teeth. Accordingly, both are in a harmonious way adapted to each other. However, this relation has not been detected by the previous researchers. The opinion ( however at a study of the lowering of the mandible) gained by Langer that the mandibular condyle moves in a sagittal direction around the lower surface of the Tuberculum Glenoid in a curve which is concentrical to the curve of this Tuberculum and who’s axis is inside of it, is not correct, at least conducting a movement with the teeth pressed against each other.
