Resumen
Background: The transversal maxillary deficiency represents one of the most frequent skeletal discrepancies of the craniofacial region. The analysis of morphological characteristics of the maxilla can be detrimental for a correct diagnosis and treatment plan. Methods: This paper shows a user-friendly digital workflow involving mirroring, superimposition, and the deviation analysis of 3D models of the maxilla in order to identify the presence of symmetry/asymmetry of the palatal vault. Such information can be helpful to clinicians in order to design an appropriate orthodontic appliance for the treatment of transversal maxillary deficiency. We also describe a case report of a seven-year-old female affected by mild transversal maxillary deficiency associated with anterior openbite. The appliance is designed after a comprehensive evaluation of the morphology of the maxilla performed by using the presented diagnostic digital workflow. Additionally, the orthodontic treatment is assisted by photobiomodulation sessions that expedite the achievement of clinical outcomes.
