Number and location of occlusal contacts in intercuspal position.

Records of intercuspal position were made in 45 healthy young adults with morphologically normal occlusions. The observed perforations were analyzed according to the frequency of occlusal contacts. Most subjects had asymmetric distribution in number and location of occlusal contacts. Regardless of symmetry, a significantly higher number of subjects had approximately seven contacts on each side that were located between all posterior teeth. Contacts were most frequent between maxillary and mandibular first and second molars.
