• AULIUS CORNELENIUS CELSUS (25 BC-AD 50 )
“If a second tooth should happen to grow in children before the first has fallen out, that which ought to be shed is to be drawn out & the new one daily pushed towards its place by means of the finger until it arrives at its proper position”.

• His greatest contributions to be prosthetic correction of cleft palate.
- First to use light wires (.016-.018) Advocated extraction to correct facial deformities
Case’s 1911 paper provoked acrimonious debate that came to be known as “Great Extraction v/s non extraction debate”
![Page 45: ORTHODONTICS IN GREECE & ROME](https://reader036.vdocuments.net/reader036/viewer/2022062314/5681351a550346895d9c71b6/html5/thumbnails/45.jpg)

CASE :Appeared in Chicago before National Dental
Association’s annual meeting in July (1911) with his paper
