Oral rehabilitation of excessive tooth wear patient usingzirconia fixed prosthesis with increased vertical dimension / 대한치과보철학회지

ABSTRACT

From the point of view of oral rehabilitation, the treatment of extensive tooth wear requires a prosthetic approach. Physiological tooth wear is considered as a normal processand generally does not require treatment, but excessive tooth wear causes problems like inadequate occlusion and esthetics. Changes of occlusal vertical dimension should bemade through accurate diagnosis and analysis. Also, the patient’s adaptation to the changed occlusal vertical dimension should be assessed over time. This case was a60-year-old male patient who complained of a decrease in chewing function and esthetics due to severe tooth wear. Full-mouth rehabilitation was performed with a tooth supportedfixed prosthesis. An occlusal stabilization splint and provisional restoration were used to evaluate the adaptation to increased occlusal vertical dimension and induce astable centric relation position. After that, monolithic zirconia prosthesis was delivered. We report this as a satisfactory functional recovery and esthetics. (J Korean AcadProsthodont 2020;58:121-9)
