“To Evaluate The Correlation Between The Mesio-Distal Width Of The Maxillary Anterior Teeth And Different Measurements Of The Distal Maxillary Arch Width-An in vitro study.”

Abstract

Introduction: In the absence of pre-extraction records, the selection of maxillary anterior teeth for the edentulous patient is mostly subjective. Several techniques using anatomic landmarks have been suggested for determining the size of maxillary anterior teeth, but there is no universally accepted method that can be used reliably.

Aim: The study aims to find the correlation between the mesiodistal width of the individual maxillary anterior teeth and different measurements of the distal maxillary arch width.

Method: Impressions of fifty dentulous participants were made using irreversible hydrocolloid impression material, and casts were prepared with Type III dental stone. The mesio-distal width of individual maxillary anterior teeth and three maxillary arch width measurements—mesial marginal ridge, central fossa, and distal marginal ridge of first molars—were obtained using a digital vernier calliper. Data were analyzed using Karl Pearson correlation.

Result:  The mesial marginal ridge width showed the highest correlation (r = 0.166) with the mesio-distal width of maxillary anterior teeth, suggesting positive linear relationship compared to the central fossa and distal marginal ridge measurements

Conclusion: A positive correlation exists between the mesio-distal width of maxillary anterior teeth and distal arch width, particularly with the mesial marginal ridge. This relationship has substantial implications for prosthodontic and restorative practices, reinforcing the importance of precise measurements for teeth selection.
