In a situation where a vertical dimension has to be increased, the normal occlusion, function and aesthetics should be restored aftertaking into consideration the neuromuscular system and temporomandibular join. In order to do this, the provisional prosthesisshould be made according to the patient''s information. Moreover, the period of adjustment should be made through the provisionalprosthesis modification, if necessary. The patient is then transferred to the final prosthesis to obtain results that are satisfactory. In themodern-day world, provisional prosthesis are replicated using three dimensional scanning and computer aided design/computer aidedmanufacturing (CAD/CAM) then made into final prosthesis. The adaptability of stomatognathic system can be judged by the PMMAprovisional restoration. Functional and aesthetical aspect can be obtained. The adjustment period can be shortened by an intraoralcorrection and proper wear between provisional restorations. By using the CAD/CAM technology that transfers the information rightinto the final prosthesis.
