I've got a client that likes to use temporary cement on his cement retained implant cases. This works ok for metal ceramic cases as the friction of the metal framework internally aids retention. Zr cases cement with temp cement just pop straight off. I'm looking at Ti Bases as an alternative and have a case I'd like to try it on, typically it's a platform with the least amount of components available, Ankylos.... I've found some Ti Bases that allow angle correction made by Arum, the only snag is the tissue depth is around 3.5 mm and the crown height is around 11mm. Is this going to be too much unsupported crown in relation to the Ti base?
