An interventional study of Osteotomy between the maxillary central incisors and Osteotomy between the maxillary lateral incisors and canines in Malocclusion, Maxillar Hypoplasia and Transverse Maxillary Deficiency, sponsored by Hospital Universitario Pedro Ernesto. Completed at 1 site in Brazil. Open to participants aged 18 Years and older, including healthy volunteers. Per ClinicalTrials.gov, last updated 2020-02-17.

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.
323 studies on the registry are indexed under Malocclusion; 85 are open to participants now.
This study's enrollment of 20 is below the median of 37 across 242 interventional studies indexed under Malocclusion.

Plan to share: No — I plan to share the data on March 24, 2020 when I going to present my Master degrees' thesis. I tried to submit an article with the data. I'm waiting for a reply
