Maxilla bone structure
Forward maxillary projection lifts the midface and shortens the apparent lower third. The scan estimates where your maxilla sits on a profile-derived percentile against Farkas-normed references.
Three of the 17 metrics map to maxillary projection. The report tags which are soft-tissue modifiable and which are surgically gated.

What the maxilla actually does
The maxilla is the largest bone in the midface. It is paired (left and right halves fuse at the intermaxillary suture in early development), holds the upper teeth, forms the floor of the orbit and the lateral nasal wall, and provides the skeletal support for the cheekbone complex above and the upper lip below. Anything that influences the midface contour passes through the maxillary position.
Forward maxillary projection (sometimes called forward growth) lifts the midface upward and outward, supports cheekbone projection from underneath, shortens the apparent vertical lower third, and prevents the soft tissue under the eyes from pooling. Recessed maxillary position (maxillary hypoplasia) drops the midface support, flattens the cheekbones, lengthens the apparent lower third, and often associates with a tired-looking eye area and a pronounced lower jaw relative to the midface.
The reference standards for maxillary position come from two sources. Farkas 1994 (Anthropometry of the Head and Face) compiled cephalometric and surface anthropometric norms across populations. Rohrich and Pessa 2008 (Plastic and Reconstructive Surgery) documented the midfacial fat compartments that overlay the bony maxilla and contribute to perceived projection. The scan uses Farkas-derived profile geometry as its reference frame.
The three metrics that estimate maxillary projection
Midface ratio
Vertical proportion of the middle third of the face (nasion to nose base, divided by total face height). Forward maxilla compacts this ratio; recessed maxilla elongates it. Farkas-normed reference distribution.
Cheekbone projection
Forward-and-outward extension of the zygomatic complex, which sits on top of the maxillary support structure. High projection correlates with forward maxillary growth; flat or indented paranasal areas correlate with recession.
Mandibular plane angle
Lower jaw angle off horizontal in left-profile photos. Inversely correlates with maxillary projection in the profile photo. Steeper angles often indicate the midface is dropping while the chin is doing structural work alone.
Paranasal contour (proxy)
Surface contour around the alar base and the lateral nose. Flat or indented contours suggest maxillary hypoplasia; full or supportive contours suggest forward projection. Estimated from profile photo geometry.
Upper lip support
Vertical position of the upper lip relative to the lower lip in profile. Maxillary recession often causes the upper lip to fall behind the lower; forward projection brings it forward.
Eye area tiredness (proxy)
Pooling of soft tissue under the eyes that often correlates with weak maxillary support of the orbital floor. A confound metric, not a primary maxillary measurement.
What is modifiable and what is not
The bony maxillary position is fixed in adults outside of orthognathic surgery (LeFort I advancement for severe maxillary retrusion). The soft-tissue presentation over the underlying skeleton is meaningfully modifiable. Body fat reduction sharpens the apparent midface contour by removing the soft layer that smooths over the bone. Posture work (chin-tucked neutral) lifts the head and reveals more of the midface in profile. Lip seal correction prevents the chronic mouth-breathing posture that drops the perceived midface support.
The report explicitly tags each maxilla-adjacent metric as structural (surgically gated) or soft-tissue (modifiable in 60 to 90 days), so the prescription lands on the right slab. Most users score above what their cephalometric position would predict because soft-tissue work alone can lift the visible composite noticeably.
Honest limits
- True cephalometric maxillary position requires a lateral cephalogram or CBCT scan from an orthodontist or oral surgeon. The profile-photo scan is a useful estimate; it is not diagnostic.
- Severe maxillary hypoplasia (SNA angle below 78 degrees) often requires orthognathic surgical consultation. The scan flags this on the paid report when the composite midface estimate falls below a threshold.
- Adult maxillary position does not respond to mewing, jaw exercises, gua sha, or any non-surgical intervention. Soft-tissue and posture work can move the appearance of projection; the bone itself does not move.
- The Farkas reference is largely Caucasian-normed. Per-population percentile bands on the paid report use East Asian, South Asian, Black, and Latino reference distributions when available.
