Mathematical Formulae to Predict the Horizontal Location of Maxillary Anterior Teeth in Edentulous People
Authors: ,
Abstract: The arrangement of anterior teeth has a significant impact on the patient's looks, communication, and
well-being. Maxillary prosthetic anterior teeth are put as close to their natural location as possible to maintain
proper anatomophysiology.The purpose of this study was to assess the relationship between the placement of
anterior teeth and the incisive papilla in dentate and then apply the findings to edentulous patients using linear
regression analysis. 114 maxillary dentate casts were selected according to predetermined inclusion criteria.
The antero-posterior length of the incisive papilla, the central and lateral incisors, and the intercanine line to the
posterior limit of the incisive papilla were all measured directly on the casts. The Pearson correlation
coefficient and linear regression analysis were used to verify the association and to develop linear regression
equations to calculate the location of the anterior teeth depending on the length of the incisive papilla. The
results showed that a significant positive linear relation was evident between the incisive papilla length and the
horizontal distances that separated the incisive papilla from the central, lateral, and intercanine lines,
respectively. As a result, three equations were formulated based on the linear model fit to calculate the
horizontal placement of central, lateral incisors, and canine tips in an edentulous patient.
