Evaluation of the incisive papilla as a guide to anterior tooth position.

The incisive papilla provides a reference point on the edentulous cast that may be helpful in determining the anteroposterior position of the artificial incisors. The results of the study suggest that the labial surface of the maxillary incisors should be 12 to 13 mm from the posterior border of the incisive papilla. This measurement was significantly smaller in the sample of dentures examined, which suggests a tendency for the anterior teeth to be placed too far posteriorly in artificial dentures.
