[Craniofacial growth under the influence of blood supply. 13. Local biomechanical aspects of bone morphogenesis].

The origin of formative forces is to be sought in genetically controlled growth processes. The forces generated by various system components are analyzed. The forces acting in mutual opposition can be illustrated by considering the brain as an intracranial force factor and the temporalis muscle as an external force factor. Apposition and resorption of bone is governed by the interaction between the stresses. The skull's primary growth centres such as the basicranial synchondroses must, like epiphyses of tubular bones, exert growth forces to overcome the restraining forces stemming from surrounding tissues. Growth can be suppressed by excessive counter-pressure, diverted by asymmetrically acting forces, and encouraged by the removal of suppressive forces.
