[Practical application of an anterior guidance reconstruction concept. 2. Clinical use of the C.C.F]

The knowledge of the biomechanical principles of position, relation and function of the anterior teeth must be used in the study of their diagnosis and restoration. The method presented here allows the simple use of functional characteristics to propose a diagnosis and ensure the restoration of the anterior guidance. The instrument necessary to achieve this goal--the C.C.F.--is easy to use with any articulator whatsoever; the non-arcon instruments nonetheless require a particular adaptation. Mounting and use of the C.C.F. are shown. In addition, the essential stages of guidance wax-up is explained. It is important to be attentive to changes in anterior teeth long axis directions, in the case of dento-maxillary dysmorphosis.
