The Significance of Inner Canthal distance in Prosthodontics.

Several anthropometric facial measurements have been suggested to aid in the estimation of the overall width of the maxillary six anterior teeth for edentulous patients. However, the inner canthal distance, which is an important anthropometric parameter, has not been investigated or reported. The inner canthal distance is the distance between the medial angles of the palpebral fissures. The relationship amongst the inner canthal distance, inter-alar width and the combined width of the maxillary anterior teeth of 310 subjects was investigated. The results indicated that the combined width of maxillary six anterior teeth may be estimated by multiplying the inner canthal distance by a factor of 1.35.King Saud Universit
