Normal maxillary arch / palate but maxillary retrusion?
« on: July 24, 2017, 06:22:06 AM »
Hi,

I have a more basic theoretical question: is it possible to have a normal maxillary arch and palate, and good arch transpalatal width, and have a recessed maxilla? Or is a normally formed arch a sign that you don't have maxillary recession?

I ask because I do feel in terms of aesthetics that I fit the profile of having a recessed maxilla -- but my nasion to point A perpendicular is normal, and I went to one of the top orthodontists in my city (Boston) and she told me my palate was absolutely not narrow and would never recommend that I receive palatal expansion, surgical or otherwise.

Yes it's entirely possible. The two observations are only correlated because they are both symptomatic of poor facial growth patterns during childhood. Sagittal maxillary positioning is absolutely a function of genetics and can be solely a function of genetics.

So some people are just born ugly.  ;D ;D that's a relief compared to how the orthotropics community chalks all aesthetics up to oral habits and diet during childhood/adolescence.

It's also true from an ethnic aspect, no? Since maxillary hypoplasia is common in Asian groups, even though many of them probably have adequate dentition and maxillary transpalatal arch width.
