title: En-masse retraction dependent on a temporary skeletal anchorage device without posterior bonding or banding in an adult with severe bidentoalveolar protrusion: seven years posttreatment.
abstract: This report describes a novel concept of en-masse retraction with temporary skeletal anchorage devices in place of posterior bonding or banding. The patient was a Korean woman, aged 24 years 4 months, with a Class II Division 1 malocclusion with severe mandibular anterior crowding. Both molars showed decalcification of the cervical areas. Partial osseointegration-based C-implants and C-tube plates were placed bilaterally between the maxillary second premolars and the first molars and in the posterior mandible. These temporary skeletal anchorage devices were used as independent appliances for full retraction of the maxillary and mandibular anterior teeth 3-dimensionally without the assistance of posterior bonded appliances. The posterior occlusion was not changed during treatment, and Class I occlusal relationships with optimal overjet and overbite were achieved. The 7-year posttreatment records showed a stable result.
