Occlusion is the last assessment to make for a fully seated crown. Articulating foils and shim stock are needed to check for occlusion. Both crown and adjacent teeth should hold shim stock firmly in the intercuspal position (ICP).A large flame shaped diamond bur is used to reduce high areas. Once ICP has been re-established the excursions can be checked preferably with a different coloured foil. Occasionally, it may be necessary to adjust the tooth opposing a restoration to avoid crown perforation or exposure of rough opaque porcelain.
