DOME zero creates a larger “DOME-shaped” space in the palate. The DOME concept was invented by Dr. Stanley Liu, DDS, MD, who recognized that people with a DOME-shaped palate (vs. a high-vaulted palate) tend to have larger nasal airways and more tongue space. And that they often breathe better and sleep better.
What does “DOME-shaped palate” mean?
A DOME-shaped palate is not just bigger,” it’s also wider and more rounded than a high-vaulted palate. The dome shape creates a larger healthier space for the tongue in the palate and a large nasal airway above it. In contrast, a narrow or high-vaulted palate limits tongue space, contributes to crowding, and promotes mouth breathing versus nose breathing.
Why the DOME shape matters
- Larger nasal airway: the palate forms the floor of the nose, so widening the palate creates a larger nasal airway and better breathing.
- More tongue space: a wider palate gives the tongue room to rest up and forward into the palate where it belongs.
- Wider, more beautiful smile: expansion supports a naturally wider smile width and better facial balance.
- More comfortable bite: a wider jaw space has more room for the teeth to fit and function better, and bite in a more comfortable way.
Dr. Liu’s DOME research
Dr. Liu not only introduced the DOME concept—he also helped bring it into modern airway care through clinical research on adult maxillary expansion and its impact on the nasal airway. Today, the DOME concept is a foundation for airway orthodontics and airway-focused dentistry.

How DOME zero fits in
DOME zero applies the DOME concept in a modern, clinician-ready system by coordinating adult expansion and clear aligners at the same time. The goal is to create a larger palate and nasal airway while also finishing with a comfortable, stable, and beautiful bite and smile.
