[QUOTE="doug, post: 84802, member: 1835"] Well, you opened a can of worms there. Not enough occlusal reduction. Trust the scanner when it tell you there's not enough room. More second angle cut on upper posteriors on the lingual. More second angle cut on lower posteriors on the buccal. Aim those functional cusp preparations towards the fossa. Move through function and look at the clearance on all preps. More "Scoop" on linguals of anteriors to accommodate long centric closure. allow "air space" on posterior preparations. There's a lot of open area on natural dentition in MIP, we need room to reproduce it in our crowns. Polish your preps. Thanks for being brave enough to ask. [/QUOTE]
