I'm not here to question, just here to smile

Surgeon did a pretty decent job on this one, I corrected a bunch of angles as you can tell but this one will be a home run.

Very nice John, finish and geometry looks great much like stock abutments. What implant system are these on?

On second look are these a mix of stock and custom?

Troy you are right it's a combo of stock/custom and the stocks are as ideal as a stock can be, again good surgeon. We are making Pmma temps first and I believe it will be zi for the finals.

Looking forward to the design tomorrow it's getting duped with master does now just incase we need to change anything down the line.

The interesting thing is this case is a mixture of 3 different implant fixture and while the buc/ling m/d placement is about as text book as you could hope for the real challenge to get the emergance on the abutments as good as they are now was the the dissimilar heights to the table of the fixtures. The centrals alone have a 4mm depth difference which can not be seen with the tissue on. #9 is an astra #8 is a straumann. The post are astra

When we did a case like this by hand, the time it took to get this results was just staggering. I can remember originally hand waxing UCLA's to full contour then cutting back to get the emergance. I then started setting denture teeth and making a matrix to speed things up. Finally we come to CAD and the design constraints are easily known and problems can be solved and plans made for better results in a fraction of the time

Like the finish on the abutments - do you plan to air-abrade before delivery to the DDS?
For WIW, it is always better to have lone standing units so that the patient can floss individual crowns.

In the past we would wax out the margin and then alox the cementing surface to give that rough look. Now we are anodizing all of our ant ti gold and find the color you achieve is indicative to the surface finish. The higher the shine the better/richer the color.

We are now experimenting with a mini hobby lathe to turn horizontal groves on the abutment that will allow us to get additional surface area for the cement to lock in but truthfully on abutments designed like this the taper is so minimal and the walls super square that we have no fear of the restoration coming off. Thess groove will help on abutments that are short in height.

Good job. Did you mill some of those abutments at you lab John?.
No I do not mill Ti, don't think I will ever jump into that market unless certain things change for us.

These abutments were design in 3shape and sent to nobel to be milled.

These retention grooves I do by hand, if you'r carefull you could have good results. So why the milling center dose not create these grooves?. But again you need to work on case first. I answered myself.

Some do .You have the option for retentive grooves or not in the order form.

How are you cutting them by hand Taye?
