Abstract: PURPOSE: To investigate the feasibility of occlusal reconstruction with IPS e.max Press for patients suffering from severely worn dentition, and to summarize the technological experience. METHODS: IPS e.max Press was used to reconstruct occlusion for one patient with severely worn dentition. Provisional restorations were fitted in worn teeth to rehabilitate the vertical dimension and centric relationship almost 3 months before final treatment. Face bow was used to transfer the general information of provisional restorations to articulator, including the plane of occlusion, anatomical outline and intercuspal position of teeth. RESULTS: After 24 months of follow-up, the masticatory efficiency and facial appearance were improved significantly, and TMJ disorder was not observed. The patient was satisfied with the prostheses.CONCLUSIONS: IPS e.max Press is an effective and reliable treatment of occlusal reconstruction.The short term effect is promoting.
