A detailed consideration of the line of occlusion

With the re-evaluation of the concept of the "line of occlusion" the author proposes a contemporary definition: "a distinctively individual line at the incisobuccal contact, with a location, position, and form to which the teeth must conform to be in normal occlusion." In other words, it is that position which the teeth must occupy to be in stability and harmony with each other and with all other anatomic structures.
