Here is a really simple case using an Astra 4.2 by 11 EV Implant with CEREC Guide and the new CEREC Guide 2 Sleeves you can purchase at the digital enamel store. Simple case, a bit deficient on the buccal.
I only have two sleeve sizes. Medium for the 4.2 and 3.6 and Large for the 4.8 and 5.4. I wanted to use a 4.8 but the ridge was just too thin.
Due to the tissue height we got an error in CEREC asking if I want to grind out the tube or leave it. Since I am laying a flap I opted to leave it. Medium guide sleeve cemented with crazy glue.
I really like how the rings on the Astra system guide the drill all the way through the drill length. Fully guided insertion.
Just a heads up, we ware filling up at out Oct 20/21 3D printing party and you can register at the link above!!
