What implant system are these on?
On second look are these a mix of stock and custom?
Like the finish on the abutments - do you plan to air-abrade before delivery to the DDS?
Good job. Did you mill some of those abutments at you lab John?.
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.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.
