Introduction: Molar protraction can be used in several clinical situations. It provides a real service to the patient, when it makes it possible to replace an implant, for example, or in case of a very damaged molar compared to the patient’s age. Material and Method: In this article, the authors describe the different molar mesialization systems in the vestibular multi-attachment technique, outlining the biomechanics of each. Discussion: The mini-screws introduction in the practices has made it possible to improve the anchorage management, which is essential in this therapy. However, it is not always offered, depending on the patient’s wishes, but also sometimes of the orthodontist’s. Conclusion: The different biomechanical situations analyzed each have their own characteristics, advantages and disadvantages. A methodical reflection must lead the practitioner to choose the system that suits him, according to his experience and practice, in order to implement this therapy for the well-being of his patients.
