Camouflage Treatment With Follow-Up And Palatal Cortical Bone Remodeling

The expanding application of skeletal anchorage systems has progressively broadened the therapeutic scope of orthodontic camouflage treatment. Nevertheless, clinicians must maintain cognizance that implant anchorage does not modify the fundamental anatomical architecture or biological properties of alveolar bone.However, we have revealed a case: Camouflage treatment of severe skeletal Class II malocclusion with maxillary protrusion led to dental overcompensation and subsequent palatal cortical bone remodeling. A case of severe maxillary protrusion with skeletal Class II malocclusion underwent camouflage orthodontic treatment, resulting in overcompensation of upper anterior teeth, with follow-up observation demonstrating remodeling of the palatal cortical bone. While Elnagar maintain that maxillary cortical bone remains relatively stable following anterior tooth retraction, Ten have observed concomitant recession of palatal alveolar bone during incisor retraction. Current evidence suggests that mechanical strain induces localized microdamage, which subsequently triggers bone remodeling through coordinated osteoclastic resorption and osteoblastic deposition to replace compromised bone regions. Substantial retraction of maxillary anterior teeth resulted in palatal cortical bone resorption. However, follow-up observations revealed stable root inclination and torque maintenance, with the surprising finding of cortical bone reformation in the palatal region. This suggests that bodily movement of anterior teeth may create favorable conditions for palatal cortical bone remodeling.
