Keynote: Dentist Case Rep
Statement of the Problem: The immediate loading protocol has become increasingly popular due to the progressive growth in demand for a reduction in treatment times. The possibility of applying this protocol would be depending on certain important factors. Application of the digital workflow in the mentioned protocol guarantees the rapidity, precision, and aesthetics. This case series aims to describe a fully digital workflow using a dual scan impression technique to fabricate immediate fixed complete dentures for zygomatic and standard implants. Methodology: All patients were looking for fixed full mouth rehabilitation. Clinical and radio-graphical analyses were undertaken. The treatment planning was discussed with every patient and informed consents were sought and obtained. The treatment commenced by digital impressions of the upper and the lower prostheses. The scan information constituted the first stereolithography (STL) file. Both prostheses were removed, and another digital impression of soft issues was undertaken to create a second STL file. During the surgery, transmucosal abutments were placed on all implants, after suturing the positions of implants were recorded using the stereophotogrammetric technique and creating a third STL file, the soft tissues after suturing were rescanned creating a fourth STL file, all STL files were aligned to have the virtual final models. The pre-design after virtual modifications was aligned with the definitive models, the provisional prostheses were milled and placed after six hours from the surgery. Conclusion & Significance: The dual-scan technique presented in this report might be effective with immediate and definitive screw-retained fixed complete dentures (FCDs), with this technique the time is reduced, the cumulative errors of conventional impression technique and the stitching discrepancy of IOs can be avoided, the clinician and patients are highly satisfied.
