The search for an esthetic appliance to treat Class III malocclusion has intrigued researchers for years. More recently, emphasis has been laid on the early correction of this malocclusion with the use of skeletal anchorage, associated with intermaxillary elastics with Class III orientation. Although this technique has revolutionized Orthodontics, there is still a need for surgical intervention. Some patients have accepted this proposal well, and others have not. Therefore, the initial problem goes back to “square one”, raising a new question. How to treat this malocclusion without surgical intervention, but at the same time, without the appliance being anti-esthetic? In seeking improvement in the esthetics of protractor appliances, an infinite number of new designs have appeared, among these the mini maxillary protractor appliance (Fig 1). But would this appliance with reduced dimensions be effective in protracting the maxilla? Searching an answer to this question, Turkish1 researchers conducted a clinical study, in which they verified the effectiveness of this appliance, in comparison with a control group. The results obtained were encouraging, seeing that this device with reduced dimensions was capable of applying traction to the maxilla, leading to dental and facial skeletal changes. Therefore, this device has become another option for the orthodontist in the early treatment of Class III malocclusion. It is worth pointing out that long term studies must be conducted due to the great potential for relapse of this type of malocclusion.
