Is there a way to reverse extraction of the four biscupids in the middle of traditional orthodontics?

No: It is possible to close the spaces without retracting the front teeth. In 30 years of practice I have never seen this scenario. However, if it were to occur temporary anchorage devices (small temporary bone implants) can be utilized as anchors to move all of the back teeth forward. Be careful of listening to those who do no have university orthodontic training. Talk to your orthodontist.

No: Once teeth are removed, they are gone. The only way to replace them is place implants or bridge work. Discuss your options with your orthodontist.

No: Once teeth are extracted, they simply cannot be place back, which would be true reversal of extraction. By definition, extraction of teeth is "non-reversable".

Best Functional posi: Orthodontics should be done to the best upper quadrant functional position. If teeth have been removed, but treatments need to stabilize a different bite position, that bite position must first be established and them treated to with orthodontics and/or put the teeth back in if they are necessary.

Yes there is: The best answer to this question is to know why it is being asked. After extraction of four bicuspids the residual space is being closed. This space can be reopened if there is a valid reason to do it. I have a friend who is an orthodontist , he treated himself with extractions, then later retreated himself and had four implants placed. Many patients need extractions for best treatment.

Problem: The extraction of 4 perfect teeth is truly a technique for a by-gone era. In my many years of practice, a majority of these patients developed significant periodontal bone loss with many ending up losing their first molars. What a waste! with so many newer and better techniques, there is rarely a situation when this outdated treatment should be considered. Talk to a good restorative dentist.

Very hard: if you try to reverse treatment plans then you will be left with space associated with the extractions,however if for some reason you or your orthodontist feels the change is better the leave the space and treat to completion with spaces

Why?: Traditionally an Orthodontist will order extractions only in those few cases where there is significant protrusion or significant crowding. Assuming you are seeing a fully qualified Orthodontic Specialist for your Rx, discuss the issues with the Orthodontist and the reasons for your concerns.
