Hi ,everyone who are preparing for ACS
i am preparing for the premolar metal ceramics preparation. For the metal ceramics, i have a question
Initially, i found some space(about 1.5mm) between upper second bicuspid mesial marginal ridge and lower one. So do i have to prepare just 0.5mm at the point of mesial marginal ridge while i cut the upper second bicuspid?
because ACS protocol indicates that incisal or occlusal reduction should be just 2mm. Actually,Don't you think it is weird slight reduction of marginal ridge could be marginal metal exposure due to the depth of the porcelain.
Please show me the answer! Thanks.
