[The convergence angle of crown preparations with clinically satisfactory retention].
A method was developed to measure the convergence angle on dies of complete crown preparations. The 132 dies measured revealed a surprising range in the convergence angles (15.5 to 30.2 degrees). The mandibular molar preparations had the greatest convergence angle. The design of mandibular molar preparations should be the subject of additional research.
