Background: Correcting Class II malocclusion with Class II elastics or functional appliances requires great patient collaboration. Here we describe two Class II cases successfully treated with an alternative approach using a fixed device designed to obviate compliance. Methods: We fitted specific Class II springs to the bilateral hooks on the stainless steel maxillary and mandibular archwires of a full fixed appliance to correct the Class II malocclusion and to promote mandibular growth. Results: The new device brought about full Class I canine and molar relationships in both treated cases and improved the maxillomandibular relationship without relying on patient collaboration. Conclusion: Class II springs appear to be a simple, fast, and effective alternative approach to Class II correction, facilitating mandibular growth even in noncompliant patients.
