Summary

To analyze in vivo occlusal accuracy and occlusal adjustment requirement, a cross-over clinical trial was designed. Two 3-unit tooth-supported posterior FDPs were planned to be made for each patient's single missing tooth gap, one with complete analog workflow (control group) and the other complete digital workflow (test group). The analog workflow aims for a porcelain fused to metal (PFM) FDP whereas the digital workflow aims for 3-unit monolithic Zr FDP. PFor half of the restorations, digital impression was planned to be taken first and to be followed by analog impression. As for the occlusal adjustment, in half of the study sites monolithic Zr FDPs were planned to be tried-in first, followed by metal-ceramic FDP and vice versa.

One investigator (DK) was assigned to prepare the restoration sites and deliver the FDPs. All monolithic Zr and all metal-ceramic FDPs were designed and fabricated by the same experienced dental technician. One investigator (HL), that was not involved in the treatment intervention was assigned to make the 3D analysis of the volumetric occlusal adjustment amount.

OTHER

Monolithic FDPs: after adjustment

After the occlusal adjustment, Occlusal relationship recording of the 3-unit monolithic FDPs which was fabricated following the complete digital work-flow.

OTHER

Metal fused porcelain FDPs: before adjustment

Before the occlusal adjustment, Occlusal relationship recording of the 3-unit metal fused porcelain FDPs which was fabricated following the complete conventional manufacturing procedure.

OTHER

Metal fused porcelain FDPs: after adjustment

After the occlusal adjustment, digital occlusal relationship recording was done of the 3-unit metal fused porcelain FDPs which was fabricated following the complete conventional manufacturing procedure.
