Table 1.

RoC of each of the cusps (sharp, medium or dull). T1–T18 represent the 18 teeth produced using the Taguchi method (i.e. T1 = first tooth produced using Taguchi method), optimum is the optimal tooth morphology, and SubOpt1–3 are the three suboptimal tooth morphologies. The subscripts next to RoC tell which cusp is being described (cusps a, b, c and d) and the direction in which the RoC is being described (1, mesiodistal plane; 2, buccolingual plane).
