Background:
Orthodontic treatment carries potential risks and complications, especially if the path of tooth movement extends beyond the alveolar bone or if the patient has a thin bone plate. This amplifies the patient's risk of complications such as bone fenestration and bone dehiscence. Hence, orthodontists should consider the patient's periodontal and dental condition during treatment and opt for a multidisciplinary approach when necessary to achieve optimal results.
Case Presentation:
This case report describes a successfully treated case of Class III malocclusion using an adjuvant therapy known as periodontally accelerated osteogenic orthodontics (PAOO). A 25-year-old man sought treatment primarily due to an evident anterior negative overjet. The patient was diagnosed with a skeletal Class III relationship and mandibular prognathism. A clinical examination revealed a severe Class III molar relationship and an anterior negative overjet. Moreover, cone-beam computed tomography revealed a thin labial bone plate in relation to the mandibular anterior teeth. The molar relation was corrected through molar distalization using miniscrews, and the mandibular incisors were retracted in conjunction with the PAOO procedure. Post-treatment outcomes demonstrated improved occlusal relationship, thickened labial bone plate of the mandibular anterior teeth, and absence of bone fenestration or dehiscence.
Conclusions:
This clinical case shows that orthodontic treatment requires a multidisciplinary approach. The favorable results indicate that PAOO is effective in maintaining alveolar bone thickness and reducing the risk of periodontal complications.
