, whenever possible we always recommend a custom abutment for this reason in particular, deep submucosal interfaces are a chalenge when shaping a stock abutment, often the predetermined margin is too ‘low'. lately we are making more ‘Atlantis' CAD abutments which are designed within the confines of a ‘virtual' finished crown to give perfect marginal position coupled with ideal emergence profile, all helps with cement management.
