WARNING: Do not use this product until you have thoroughly read and understood these instructions.Repair of Porcelain-Fused-to-Metal or Zirconia/Alumina RestorationsStep1Always use a rubber dam. The use ofa rubber dam during porcelain repairprovides several benefits, includingisolation from saliva during bondingand soft-tissue protection when usinghydrofluoric acid intraorally.Step4Step7Step2Apply 1 coat of PORCELAIN PRIMER to theetched porcelain surface and allow to dwellfor 30 seconds. Dry with air syringe.Allow to self cure, or light cure for 5 seconds.An oxygen inhibited layer will be present onthe surface once the curing process hascompleted. This is normal for this material.Step5Step8Remove the glaze & bevel (45 degree) theporcelain around the area to be repaired.Place BARRIER GEL on gingival tissue thatmay be exposed or porcelain to protect areaswhere etching is not desired.Step3Apply 1-2 coats of Z-PRIME Plus to theexposed metal/zirconia/alumina & dry with anair syringe for 3-5 seconds.Apply a thin layer of PORCELAIN BONDINGRESIN to the repair site.
