Determination of jaw relationships in edentulous patients is a complex process which is determined by the reference position. Jaw relation we share on the determination of the vertical dimension, which we first determine and on determination of the horizontal dimension. The vertical dimension of occlusion is the height of the lower third part of the face. She is determined by physiological rest position and freeway interocclusal distance. In determining the vertical dimension can help us objective indicators such as old photographs, models, old dentures, radiographs and other. Methods to determine the rest position are muscle fatigue, speech, facial expression, parallelism of ridges. The horizontal dimension indicates the relationship of the mandible to the maxilla, and according to the temporomandibular joint in the horizontal plane. For her determination we use centric relation position in which we are trying to bring the mandible. Methods for determining the horizontal relation we sort in passive and active, and the methods of interocclusal registration and graphical methods of registration. The most accurate method is the method of determination by the gothic arch because we have reproducible graphic registrat border movements, which end at the same point, or in the centric relation position.
