Brief summary
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).
Detailed description
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.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Bone expansion and dental inclination | 1-2 months post-expansion. | Assessment of bone expansion and dental inclination through Cone Beam computed tomography (CBCT) images |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Patient´s perception | 2 months post-expansion. | 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. |
| Periodontal effects | 2 months post-expansion. | Assessment of periodontal changes in the teeth adjacent to the segmentation, through periodontal probing |
| Surgery time | During surgery | Time elapsed during surgery. |
