Relationship of the maxillary central incisors and canines to the incisive papilla

Summary Four hundred and thirty dentulous casts in normal alignment and Angle's Class I Relationship were examined. The results indicated a relationship between arch shape and the intercanine line with particular reference to the way the latter passed through the incisive papilla. The suggestion is made that in the preliminary location of the anterior teeth during construction of full dentures, the average distance of incisors and canines from the incisive papilla could be used as starting points.
