Demand for aesthetic prosthetic appliances in addition to restoration of such functions as mastication and pronunciation has been increasing. As a result, anterior teeth with individual tooth forms have been made available commercially. This trend indeed made the range of selection of tooth form wider. There is however a question about ratio of tooth size of these commercially available anterior teeth. Therefore, widths of commercially available anterior teeth of three basic types, tapering, ovoid, and square, were measured and compared with the measurements of natural teeth which had been examined and compiled by our department. Livdent had small ratios for its lateral incisors in the ovoid type and small widths for its canines on the whole excluding the tapering type. Endura had small ratios for its lateral incisors in the tapering type and ovoid type and small canines on the whole. Its square type showed ratios similar to those of natural teeth. Duradent showed little difference in all forms for the upper anterior teeth. Its lateral incisors were slightly small. As described above, these artificial teeth showed quite small width ratios for the lateral incisors in general and small canines in nearly all types.
