“This book on early treatment should help even the most thoroughly trained residents and young practitioners to bypass many years of learning from their own mistakes. For those of us with more extensive experience, it offers the opportunity to reconsider concepts we thought we knew without a doubt, and possibly change how we do some things for the better....I expect it to become a required text in many residency programs, but I cannot imagine a course in residency or post-residency that would provide a better foundation in early orthodontic treatment.”Journal of Clinical Orthodontics, August 2023, by Robert Kazmierski, DMD, MS
