The curve of Spee (COS) was first described by Spee in 1890, who used skulls with abraded teeth to define a line of occlusion. He defined the line of occlusion as the line on a cylinder tangent to the anterior border of the condyle, the occlusal surface of the second molar, and the incisal edges of the mandibular incisors.[] Spee …
