message board Tell Me About Extracting All the 5s A documented look at how a change in extraction philosophy can lead to a nice finish NY sent Member Since: 10/10/05 Post: 1 of 34 Final photos in post 28. I read on this board about opting to extract the 5s instead of 4s as a first choice. I seem to come across a lot more extraction cases in practice than I thought I would. Recently, I started thinking more about the 5s-vs.-4s decision. Here is one that seems like the 4s would be so easy to take, but the 5s might be a better choice. Upper 5s are so much smaller than the 4s, and the lower 5s are so much larger than the 4s. Patient is 16 years old and three of her second molars are slow to erupt. I will be recommending exposure of these so we can watch them during treatment. Solid Class I. 16 MAY 2017 // orthotown.comhttp://www.orthotown.com
