Camouflage Treatment of Skeletal Class III Patient with Anterior Crossbite, Spaced Dentition and Missing Mandibular Left First Molar

Nonsurgical camouflage orthodontic treatment can be effective in carefully selected patients with mild to moderate Class III malocclusion. After growth is complete, the only way to camouflage the skeletal Class III malocclusion is through dentoalveolar compensation. And in this borderline case, the use of micro-implant is a viable option. This clinical case report presents the use of micro-implant to correct a skeletal Class III malocclusion with anterior crossbite and spaced dentition. Careful biomechanical consideration was used to close the missing mandibular left first molar space by protracting the second molar. After 28 months of treatment, adequate overbite and overjet relationship were obtained. Occlusion and smile esthetics were significantly improved.
