Single Crown Design Glidewell fastmill.io Mill

I make Bruxzir NOW crowns with this software and Fastmill and I can assure you that the -350 setting will take the crown out of occlusion. Better to have light occlusal contact on a molar than no contact. Natural teeth will supra-erupt into occlusion eventually but the result is not predictable. The -350 could make sense for an implant crown, an RCT treated tooth, or an ankylosed tooth, since these teeth don't compress like normal, healthy teeth. The healthy teeth have a proprioceptive ligament around them (PDL) to handle compression and give feedback. Also, it's better to adjust the occlusion of the crown until balanced and comfortable vs giving more work to the adjacent teeth. I would recommend recording your patients occlusion with occlusal ribbon/paper and an intraoral photo prior to starting a crown preparation, then trying to get a near identical occlusion (including adjacent teeth) when designing the crown. The software should show the occlusal contact measurements of the adjacent teeth so that you can design the crown to have a similar amount of contact.
This DOES NOT APPLY if you are planning to do occlusal adjustment of the arch due to an existing malocclusion.

So does new in office milling machine from Glidewell which can mill Bruxzir requires oven or not?
