Photoelastic analysis of stresses in resin-bonded cingulum rest seats.
Two-dimensional photoelastic analysis of resin-bonded cingulum rest seats demonstrated improvement in stress distribution when the lingual surface of the tooth was prepared with a cingulum groove. This preparation is more important for teeth that are more vertically or lingually oriented and have flatter lingual surfaces, such as mandibular canines.
