Bernina's screw-retained crown insures successful restorations that last. With screw-retained crowns, crown failure due to excess sub-gingival cementation is a thing of the past. The full zirconia crown with titanium base is customized to fit directly to the implant, eliminating the need for an abutment, and thus, cement. Screw-retained crowns provide the stability of a fixed implant solution with the retrievability of a removable solution. Z-Tek™ Screw-Retained Full Zirconia Implant crowns can also be fabricated with a cutback and layered option.
