11. The Tropic Premise
But if the tongue is chronically held away from the palate…
…the maxilla collapses in all three dimensions.

12. Then the Mandible Adapts
If the mandible stay with maxilla: Class I Crowded
12Thursday, June 6, 13
13. Then the Mandible Adapts
Mouthbreathing and/or tongue thrust hinders growth : Class II
13Thursday, June 6, 13
14. Then the Mandible Adapts
Low Tongue keeps mandible growing forward: Class III

18. The relationship
between retruded chins
and airway obstruction!
Both infants and
adults die from
obstructed airways!
(Grant’s Atlas of Anatomy, Fifth Edition, 1962, Williams & Wilkins)

20. Predictive factors that puts an
individual at risk for OSA include:
• Large body mass index (obese)
• Large neck size
• High palate
• Narrow dental arches
• Overjet (jaw back - retrognathic)
IF the individual does not have a large neck and/or body
mass, then the predictive value for being at risk for OSA is
based on a high palate, narrow dental arches and overjet.
From Kushia and Guilleminault, 1997

21. Pharyngeal Airspace
Three-dimensional assessment of pharyngeal airway
in nasal- and mouth-breathing children
Alves, M, et.al., Int J Ped ORL 75 (2011) 1195–1199
Cone Beam and Airway analysis tool

22. Pharyngeal Airspace
•Exam for Mouthbreathing
•the habitual posture of the lips
•size and shape of the nostrils
•control reflex of the Alar Nasalis
•Glatzel mirror test
•Rhinoscopy
•Adenoid hypertrophy
25 Nasal breathers, 25 mouth breathers,
Avg 8-9 y/o
22Thursday, June 6, 13
23. Pharyngeal Airspace
Mouthbreathers have significantly
smaller airway space.
(measurements PAS-OccL, PAS-UP, airway volume, area and minimum axial area)

27. Big Problem!
… except for
bimaxillary advancement surgery,
conventional orthodontics has
no workable protocols for
correcting this type of malocclusion
in the late mixed or permanent dentitions.
27Thursday, June 6, 13
28. Treatment
The one common feature of posture-related malocclusion is
Maxillary Collapse

29. Treatment
What is the appropriate treatment for a Collapsed Maxilla?
29Thursday, June 6, 13
40. Treatment
The appropriate treatment for a Collapsed Maxilla…
Moves the Maxilla up and forward…
AND the Mandible rotates and moves forward
