Maxillary Protrusion and Retrusion
Maxillary protrusion and retrusion is how anteriorly positioned your palate is in relation to your neurocranium.
Whether a maxilla is recessed or not recessed depends on the relationship between the positions of the palate, eyes, and mandible. And the space in the airway.
Recessed maxilla indicators:
Maxillary 3Dness and Flatness
Maxillary “3D”ness is an aesthetic look that comes from:
Unlike protrusion/retrusion, 3Dness/flatness is an entirely aesthetic feature and has no bearing on health.
3Dness/flatness is closely related to the orbitomaxillary plane angle. More about that here:

Examples
The gorilla maxilla shows the difference between forward-grownness and 3Dness. The gorilla maxilla is extremely forward-protruding, but it’s flat as fuck, literally flatter than an Asian maxilla:
The human maxilla’s teeth are more retracted and tucked under the eyes, but the shape of the central maxilla is much less flat:
Mew Cope
Mouth breathing and shit oral posture can make the maxilla grow improperly, but that has to do with positioning (protrusion/retrusion) only. Mewing from birth would’ve done absolutely nothing for your maxilla’s 3Dness/flatness.

Recessed maxilla indicators:
- Negative orbital vector
- Nasolabial folds
- Retrognathic profile
- Underbite (class III malocclusion)
- Teeth look inwardly set when smiling
Maxillary 3Dness and Flatness
Maxillary “3D”ness is an aesthetic look that comes from:
- anterior projection of the paranasal area, nasal sill, anterior nasal spine, and pyriform aperture
- backwardly-angled zygomatic processes of the maxilla (the “connecting wings” that border the zygos) making the midface look fox-like as opposed to pancake
