Evolution of articulators through the years has given an insight to the researchers trying to develop a mechanical device that simulates the jaw members and its movements.The purpose of using an articulator is to develop a prosthesis that will be harmonious in the oral cavity. Various articulators have been developed and are being improved upon as and when the functions of the jaws are understood better. Accordingly, in the present day, the availability of articulators range from simple hinge type to fully adjustable articulators. Selection of articulators depends upon the clinical...

Full mouth rehabilitation entails the performance of all the procedures necessary to produce healthy, esthetic, well functioning, and self-maintaining masticatory mechanism. Occlusal rehabilitation therefore involves restoring the dentate or a partially dentate mouth. The aim is to provide an orderly pattern of occlusal contact and articulation that will optimize oral function, occlusal stability and esthetics.Various factors, general and specific recommendation and procedural steps of occlusal rehabilitation have been discussed. We must also remember that not all patients can be successfully...

The success of fixed Prosthodontic restoration is largely dependent upon the long term health and stability of the surrounding periodontal structures. Marginal integrity is one of the basic criteria of principals of tooth preparation. The inability of the impression materials to adequately displace soft tissues, fluids or debris mandates adequate isolation. The gingival displacement procedures like use of retraction cord allows the impression material to flow apical to the subgingival finish line thereby exposing it and an area apical to it. These procedures lead to easy instrumentation,...
