Effects of pre-applied orthodontic force on the regeneration of periodontal tissues in tooth replantation.

- Korean J Orthod 2019;49:299–309

The authors' efforts in doing a complicated experiment to find the biologic effect of pre-applied orthodontic force on the regeneration of periodontal ligament (PDL) tissues for tooth replantation procedure were appreciated. For better understanding of mine as a reader and an orthodontic clinician, I would like to ask some questions.

Q1. The authors luxated the teeth and replanted them in their original sockets. In this case, the donor site is the recipient site. That means that the preapplied orthodontic force might affect the donor site, the recipient site, or both at the same time. Could you please explain more in detail why you could interpret the result more focused at the effect on the donor site rather than the recipient site?

Q2. Would you please suggest a clinical protocol for preparing the donor and/or recipient site for auto-transplantation in a stepwise manner, which can be applicable to real treatment? Also, please discuss how much force and in which direction is recommended and how long we should wait after each step until proceeding to the next.

Q3. According to your interests and experience, if there are any, please share with us your opinion on how to make up a team to accomplish the successful auto-transplantation.
