INJECTION TECHNIQUE with Easy Form flask
Model preparation
A gypsum model with implant analogues has been casted using GC FUJIROCK. EXACLEAR, clear vinyl polysiloxane is used as gingiva mask. This will allow us to photo polymerise the basal part of the injected GRADIA PLUS composite.



Digital design
After scanning the model in the Aadva ® Lab Scan, a full anatomical, digital mock-up is designed and printed with GC Temp PRINT. The anatomical design of the mock-up was digitally reduced and milled in titanium.



Flask preparation
The mock-up is screwed onto the model and placed into a flask. Screwholes are then sealed with a bit of wax and the model is fixed into the flask with putty.
Fix the sprues onto the mock-up and carefully check their position with the top of the flask onto it. The sprues should be postioned in the middle of the hole.
A clear silicone is used to fill the entire flask. For easy removal of the top part after curing, coat the putty surface first with a bit of vaseline or a dedicated separator.



Framework preparation
After milling, the titanium framework is prepared, sandblasted, cleaned and METAL PRIMER Z is applied on the surface and letto dry. A first, thin layer of opaque is applied and light cured for 1 minute. Repeat this process until the metal is completely masked.
Cervical and occlusal areas are covered with small amounts of LB-orange to create a warm, in-depth effect. Light cure. Screw the framework on the model, push a clot of telfon in the screwholes and seal with wax.



Injection procedure
Check carefully if all wax residue from the sprues wasremoved. Light Body A can then be injected into the mold. Let the composite flow from sprue to sprue until it gently comes out. Place a finger onto the channels and slightly apply pressure.
