It has been said that form and function are two halves of the developmental sphere that help guide normal growth. In a similar manner dysfunction and compensation are two halves of a dysfunctional growth and adaptation process.
The growth and adaptation of the upper quadrant is a relational process between the structural development of the component parts and the abilities of these components to function. When this process occurs in a relational manner there is minimal compromise in form or function.
The condyle should contact the central avascular portion of the disc which should function against the anterior slope of the eminence. There should be a consistent contact of these structures in all movements without any displacement or dislocation of the disk. The joint structure should be supported by normal muscle function with a Class I mutually protected occlusion.
