Background

Malocclusion affects the patient's aesthetics, periodontal and mental health. With the development of economy, more and more adults are treated with orthodontic treatment, but treatment time and cost lasting 2-3 years is a major challenge in adult orthodontics. How to shorten the tooth movement time and thus the time for the entire orthodontic treatment is the focus of research by many clinicians and researchers. In recent years, Periodontal Accelerated osteogenesis assisted orthodontic treatment (PAOO) has been effective in accelerating orthodontic tooth movement, and this technique purposefully cuts alveolar bone cortex through surgery to reduce the resistance of natural bone to movement of orthodontic teeth, thereby shortening the entire orthodontic treatment period. The technology can also reduce the traditional complications of orthodontic treatment such as tooth root absorption, demineralization and the like; meanwhile, the technology can effectively improve the quantity and quality of periodontal tissues because the bone grafting obtains more bone support.

The removal of cortical bone around the tooth root is the key of PAOO, and the operator should leave the crest of the alveolar ridge for 2-3mm during operation to avoid important anatomical structures such as maxillary sinus, inferior alveolar neural tube, mental foramen, tooth root and the like, thereby avoiding iatrogenic injury. Many times, the root portions are very close to each other due to crowding of the dentition, and great care must be taken to avoid unnecessary iatrogenic damage.

However, the current position location of the bone and cortex removal of the PAOO operation is that a periodontist combines with CBCT of a patient, and the determined result is that the anatomical structure of an operation area is lack of accurate knowledge, so that the operation efficiency is low, the risk is high, and the probability of occurrence of iatrogenic injuries such as tooth root injury and the like is high especially for a novice doctor who just starts to contact the operation.
