Tooth wear is loss of surface of teeth, and may be classified into physiological and pathologic wear. When tooth wear is accelerated excessively, it is pathologic tooth wear. Pathologic tooth wear may result in many problems including decrease of occlusal vertical dimension, as well as unacceptable damage to anterior guidance. In this study, the patient had loss of posterior teeth and anterior severely worn dentition. Vertical dimension analysis was conducted and 3 mm increase of vertical dimension was determined. After 8 weeks of stabilization period with temporary prostheses, definitive restoration with fixed dental prosthesis and partial removable denture prosthesis were accomplished and satisfactory outcomes were achieved in functional and esthetic aspects.

The patient was 58 years old male and visited for the treatment of missing teeth and aesthetic restoration resulted from abrasion. Full mouth rehabilitation with the increase of vertical dimension was planned through oral examination, radiographic examination, model examination and the evaluation of vertical dimension. The increasing amount of vertical dimension was determined 4mm by using facial measurement. Centric occlusion was determined. Then, vertical dimension was increased 4 mm on articulator. Diagnostic wax-up was conducted. To evaluate whether increase of vertical dimension is proper, follow-up after installation of provisional restoration was observed and continuous check and adjustment was conducted. In this period, prognostic poor teeth was extracted, and endodontic, periodontic treatment and implant was conducted. The group function which bear lateral force on natural teeth was set up to make stable occlusal contact at centric occlusion and reduce lateral force unfavorable to implant. After long term follow-up on patient mouth, the vertical dimension of provisional restoration was relocationed equally to final restoration. This case is reported that the patient, as mentioned above, who has decreased vertical dimension caused by excessive abrasion was recovered aesthetic, functional factors through prosthodontic treatment with increasing vertical dimension.
