Summary of Dr Elie's research regarding space closure mechanics for missing upper lateral incisors

· Patients with missing upper lateral incisors usually have hypoplastic maxilla

· Clinical trial investigating mechanics to advance maxilla and close space

P: Class 1 / class 3 cases, non-extraction lower arch
I: Fixed appliances to close space in the upper arch
C: Nil
O: Maxillary advancement and inclination change in the upper arch

Method
· TADs in lower 3-4 region
· Class 3 elastics from TAD to upper 7s

Results
· Advancement of maxilla, SNA increase by 1.3o
· No changes to upper incisor inclination
· Mesial movement of upper molars 5mm

Conclusion
· Using treatment protocol, it is possible to advance the maxilla and close space for missing upper lateral incisors

Critique
· Side affects of counter clockwise rotation of maxilla
