Abstract
Patient: A 54-year-old male patient complained of masticatory disturbance caused by severe tooth wear. To address the decreased occlusal vertical dimension (OVD) and aesthetic disturbance, provisional restorations which provided an appropriate occlusal relationship aesthetically and functionally were applied. The provisional restorations were regularly adjusted based on the findings of Gothic arch tracing for 14 months. After verifying the improvement in aesthetic and masticatory function, the final prostheses were applied to the patient. The prognosis has been excellent during the 4-year follow-up.
Discussion: In this patient with oral rehabilitation including the correction of OVD, the adjustment of provisional restorations using Gothic arch significantly contributed to the determination of mandibular position. As a result, his occlusal relation after the occlusal reconstruction could be maintained stably.
Conclusion: In this patient with infraocclusion, a stable outcome was achieved by adjusting the provisional restorations based on the long-term assessment of mandibular movements.
