14. THE LAW OF GROWTH RELATIVITY – An extension of Wolff’s law “Bone architecture is influenced by the neuromuscular and the contiguous, non-muscular, viscoelastic tissues anchored to the glenoid fossa and the altered dynamics of the fluids enveloping bone.” Improved clinical use of Twin-block and Herbst as a result of radiating viscoelastic tissue forces on the condyle and fossa in treatment and long-term retention: Growth relativity John C.
