Introduction: Maxillary collapse is defined as an alteration of the maxillary complex due to an excessive vertical growth of it in patients. (1) Some of the clinical differences manifested by patients are unilateral and bilateral posterior crossbite, crowded teeth, narrow palate, and a V-shaped arch. The Pont’s index, described by Dr. Pont in 1909 and developed in French population predicts the width necessary for the proper alignment of the teeth in the maxillary arch. (2, 3) The 3Shape® system and scanner collects information of the maxilla, denting or clay models. The 3D images it provides are a useful tool for estimating maxillary collapse since they allow us to carry out more accurate measuring at a lower difficulty. (4)
Objective: Classify and identify maxillary collapse in students aged between 9 and 12.
Results: A prevalence of 28 students was obtained who presented a transverse distance in the premolar and molar area that was less than that indicated by Pont’s index, representing 53% of the sample. 
Conclusions: The timely diagnosis of maxillary collapse in children provides us with a wide range of conservative treatments that would help in the correction of this condition.
