The question is what do you want to make to buy very expensive abutments from one of the major labels like Atlantis or cheaper in the same quality from for example Medentika they came to US too. Buy a ti abutment for 140 Euro ore make a zirkon hybrid for 120 Euro or a Ti for 100 Euro or less . I personaly make 95 % hybrid zirkon why should i make a ti abutment to have problems while the margin says asta la vista . You can go with the prep 1 mm under the margin no cementation problems and if the margin has a little rezidive no problem there is zirkon in the same color not this wonderful grey color. Up to 5 units you can create a split file making abutment an crown structure at on time if your mill works right an the ti interface has a nodge .for rotation secure . Behind every scanmarker is a placeholder this is adapted to the ti interface most of them are very different so same implant Nobel Replace scan markers , Wieland, Zirkonzahn , Nobel, Medentika, NT, all the scan markers are different the ti cement base are different only the old !!!! NT, and old Medentika scanmarkers and the old ti bases are the same. If you make a individual hybrid abutment there are sometimes adaptions in the placeholder ( part behind the scanmarker) you cant see depended on the production process . For example the NT ti cement bases are 30 my smaller than the placeholders its for the cement gap . If you want to make a ti abutment there is a conical srew seat behind at zirkon a flat, multi unit direct screw retained parts have different deep cut adaptions on the interface an so on and on !!!!!. Scanmarker have a different precision , if you want to make a bar you cant use a scanmarker with 20 my volume deviation rotation deviation is no problem, a laser scanner is different from white light problems with hard edges if you make only a single abutment no problem but on a 3 unit bridge split file ore screw retained part well.Their is a little bit more behind and most of it is secret. So if you by Atlantis you can send to Atlantis ore you find somebody who tells you i can do it too ???!!!. Same same but different .
