Restoration can be from single tooth replacement to 14-unit bridges
Where moderate to severe bone resorption has occurred
When screw retained restorations are desired
When potential retrievability is needed
For long lasting implant supported restorations
For the most discerning
Izir clinical and laboratory protocols are predictable, efficient and practical
Scanning includes scan of diagnostic wax ups or study models. Then CAD is complete using the industries best in class scanner and design software.
A PMMA provisional is milled using industrially processed acrylic. The gum material is layered by hand using composite. This bridge is used to ensure predictability of the final restoration.
The STL file is miiled again from a CAP FZ (full contour zirconia) disc. The milling process is done on a dental specific 5 axis mill. This will serve as the final restoration.
The green state zirconia is post processed and a multi shading process is done in the pre-sintered state. Once the coloring is complete the bridge will be sintered at around 1450 degrees centigrade for about 9 hours.
After sintering the final restoration, pink porcelain is applied to simulate lost soft tissue. The case is finalized and stain and glazed with GC Luster Paste.
The 2-CONnect titanium inserts are cemented into the zirconia bridge and the case is ready for insertion.
Final Izir bridge is screwed to place and the screw access hole are filled.
