This study evaluates 2 Techniques of Surgically Assisted Rapid Maxillary Expansion (SARME) in the treatment of maxillary transverse deficiency. Half of participants will undergo an osteotomy between the maxillary central incisors, while the other half will undergo an osteotomy between the maxillary lateral incisors and canines (bilateral osteotomies).
Surgically Assisted Rapid Maxillary Expansion (SARME) can be performed by a osteotomy between the maxillary central incisors and by osteotomies between the maxillary lateral incisors and canines (bilateral). Both techniques treat transverse maxillary hypoplasia, but they do so with different effects on esthetics, periodontium, teeth and bone expansion.

Bone expansion and dental inclination
Assessment of bone expansion and dental inclination through Cone Beam computed tomography (CBCT) images
Time frame: 1-2 months post-expansion.
Patient´s perception
Patient´s cosmetic perception of his or her smile on a visual analogue scale (VAS) ranging from 0 to 10, where "0" represents total dissatisfaction and "10" represents total satisfaction with the postoperative smile.
Time frame: 2 months post-expansion.
Periodontal effects
Assessment of periodontal changes in the teeth adjacent to the segmentation, through periodontal probing
Time frame: 2 months post-expansion.
Surgery time
Time elapsed during surgery.
Time frame: During surgery
