Case Description
The patient presented with a skeletal and dental Class II malocclusion characterized by significant crowding in the lower dental arch, notable dental rotations, and protrusion of the upper dentition. The upper arch displayed flaring of the incisors contributing to the protrusive profile, while the lower arch exhibited insufficient space and misalignment due to moderate crowding.
A camouflage treatment plan was selected to correct the malocclusion without the need for orthognathic surgery. The treatment involved bilateral extraction of the lower first premolars to relieve crowding and allow proper alignment and retraction of the anterior teeth. Additionally, the upper dental arch underwent stabilization and alignment (“sterilization” interpreted as leveling, aligning, and coordinating the arch) to address the protrusion and establish proper interarch relationships.
Fixed orthodontic appliances were placed on both arches. Over the course of 24 months, progressive alignment, space closure, and arch coordination were carried out. Anchorage was carefully managed to ensure controlled retraction of the lower anterior segment and correction of the Class II dental relationship.
By the end of the two-year treatment period, the patient successfully achieved a stable Class I occlusion with improved dental alignment, corrected lower-arch crowding, harmonized arch forms, and an overall enhanced esthetic profile. The results demonstrated good functional occlusion and satisfactory orthodontic stability.
