Introduction: Class III dysmorphia, classically distributed in hereditary or functional etiology, have often multifactorial causes. Breaking the dysmorpho-dysfunctional cascade with early treatment may seem to be an essential alternative to give growth a new orientation. Whether the treatments are preventive, interceptive with or without an appliance, orthodontic or surgical (early, first-line or late), this takes more account of the clinical form than of age. Materials and Methods: The authors, through clinical cases, will develop their therapeutic approach, based on clinical common sense. Conclusion: Waiting to act at the right time is essential to set up treatments based on proven therapies.
