The article discusses the use of posterior templates for cusp analysis of the symmetrical bilateral curves conceptualized by scientists Graf von Spee and Wilson. According to the concept, the maxillary dentition was like the surface of a sphere around which the mandibular teeth revolved. In 1981, an optician was engaged for accurately grinding convex radii on a set of glass disks for providing a series of configurations suitable for the analysis of the curves of the cusps of the mandibular teeth. It is stated that a template analysis of the cause for tooth fracture or loss will remove the error. It is mentioned that occlusal adjustment with selective grinding after template analysis of diagnostic casts gives improved curves of Spee and Wilson and a harmonious buccal arch form.
