[QUOTE="Chalky, post: 299929, member: 13047"] I mill a lot of splints on a motion 2 mill too (well 2 actually!),I have just ticked over 2000 in total this week. something to consider that we initially didn't factor properly was the tool use and cost associated. milling pmma will eat your tools compared to zirconia... I am yet to find an after market bur that performs as well as the AG burs so I have to pay premium for cutting tools that are reliable, all after market tools that I have tried break! this also costs time and money in repeating the program etc... it generally takes about 1 hour and 25 - 1hr 40 to mill one splint, in a wet strategy. going between milling dry and wet will take a bit of figuring out to make sure that you look after your mill, properly drying it out etc.. I would also be hesitant to go completely modeless in doing this, splints are a bit of a tricky thing to get right... each case needs to be assessed on its own merits, undercuts are very different from case to case and there is not 'one set of parameters that fits all' cases. you need to understand the parameter values and know definitively what it is you are adjusting in order to get things to work. this has taken me a lot of trial and error in the early days to understand and get right. having said all of this I very occasionally go modeless with pretty good success and have very reliable and consistent results.
