Dental occlusion represent the function of dentomaxillary system at which realization participate all the components of that system holding the equilibrium between them. Setting up the treatment with dental bridges in partial edentuluous is rule by some principles that have aims like restore the morphology and functions change by edentuluous condition and also prevention disorders of remaining teeth and other structures and functions of dentomaxillary system. During the prosthetic treatment with fixed bridgeworks in clinical cases presents in this study , we used also terapeutical techniques specifically other dental domains like endodontology and oral surgery. For avoid the appearance of occlusal dysfunction is necessary a good knowledge and respecting the biomorphocinematic behaviour of dentomaxillary system structure under action of occlusal force during mastication and also biomechanical rules that influence the functional equilibrium of teeth and dental bridges.
