[QUOTE="cckowali, post: 360978, member: 6593"] Hello all, we have been having some very odd occlusal issues recently that have me flummoxed. We keep running into high occlusions that only exist in the patients mouth. Everything looks good on our models and designs but when the Dr. goes to insert he is sometimes grinding almost a mm away. The issue has occurred with both FCZ and PFM restorations and only occurs sporadically and only with some Drs. Due to it's occurrence in different materials and it's only occasional nature isolating the reason has become very difficult. This issues are only present on traditional impressions and not scanned cases. Have any of you run into an issue like this before and if so how were you able to correct it? We have double checked all our settings for our stone mix, recalibrated our mill and sintering furnace, checked to make sure that all shrinkage rates for zirconia were entered correctly and just about anything else that has crossed our minds to try to troubleshoot the issue. If anyone has any ideas that could save me from putting my head through a wall they would be greatly appreciated. [/QUOTE]
