A case of camouflage orthodontic treatment using multi-bracket and aligner type orthodontic appliances in a patient with short-rooted teeth and skeletal class III malocclusion

This case report describes camouflage orthodontic treatment for skeletal class III malocclusion with short-rooted and crowded maxillary teeth.The patient was a 22-year-and-11-month-old woman with skeletal class III malocclusion.She had previously undergone extraction of an impacted maxillary left canine tooth.The occlusal relationship of the molars was Angle class I on both sides.The treatment goals were to establish a class I molar relationship, achieve proper overjet and overbite, and improve the dental midline.The right upper and lower second premolars and the left lower first premolar were extracted, and active orthodontic treatment was performed.After leveling with a multi-bracket appliance, the extraction spaces were closed.During this process, the maxillary incisors were treated without bracket placement.After removing the multi-bracket appliance, detailing was performed using an aligner-type orthodontic appliance.It is presumed that the consideration given to the orthodontic forces applied to the maxillary anterior teeth during active orthodontic treatment made it possible to suppress the progression of root resorption and achieve a good treatment outcome with a high level of patient satisfaction.
