Surgically Facilitated Orthodontic Therapy
Surgically facilitated orthodontic therapy (SFOT) is a group of Orthodontics, orthodontic procedures; they can be broadly divided into two main categories. Types The less invasive type uses alveolar corticotomies and is aimed at augmenting the alveolar bone deficiencies and shortening the orthodontic treatment time. Such procedures may also be referred to as accelerated osteogenic orthodontics (AOO), periodontally accelerated osteogenic orthodontics (PAOO), corticotomy-assisted orthodontic treatment (CAOT), selective alveolar decortication (SAD), or corticotomy-facilitated orthodontics (CFO) a.k.a. speedy orthodontics. Various techniques have been introduced, but they mainly involve creating corticotomies in the alveolar bone, creating a Regional Acceleratory Phenomenon (RAP) that leads to increased bone turnover, decreased mineral content of the alveolar bone, and thus faster tooth movement and bone remodeling. These techniques also underlie PAOO, where simultaneous bone augmentatio ...

Orthodontics
Orthodontics is a dentistry specialty that addresses the diagnosis, prevention, management, and correction of mal-positioned teeth and jaws, and misaligned bite patterns. It may also address the modification of facial growth, known as dentofacial orthopedics. Abnormal alignment of the teeth and jaws is very common. Nearly 50% of the developed world's population, according to the American Association of Orthodontics, has malocclusions severe enough to benefit from orthodontic treatment: although this figure decreases to less than 10% according to the same AAO statement when referring to medically necessary orthodontics. However, conclusive scientific evidence for the health benefits of orthodontic treatment is lacking, although patients with completed orthodontic treatment have reported a higher quality of life than that of untreated patients undergoing orthodontic treatment. Treatment may require several months to a few years, and entails using dental braces and other appliances t ...

Regional Acceleratory Phenomenon
Regional acceleratory phenomenon (RAP) is a sudden acceleration of normal tissue processes in reaction to noxious stimuli. It has been exploited in treatments such as the healing of atrophic or oligotrophic nonunions and surgically facilitated orthodontic therapy. Background In the early 1980s, American orthopedist Harold Frost published a review article detailing then known experiences with regional acceleratory phenomena, which can be caused by injuries such as fractures and burns, afflictions such as acute paralysis and arthritis, bone movement such as implant placement and orthodontics, as well as vitamin D, thyroxine, and electrical stimuli. Once evoked, processes such as perfusion, the growth of skin, bone and other connective tissues, as well as their healing, turnover and remodeling can all accelerate beyond normal values. More overt manifestations include warmness of an affected region, decreased bone density, and increased bone plasticity. In rat tibia, more intense R ...

Piezoelectric Surgery
Piezoelectric bone surgery is a process that utilizes piezoelectric vibrations in the application of cutting bone tissue. The process was patented by Fernando Bianchetti, Domenico Vercellotti, and Tomaso Vercellotti. It was first used clinically in 1988. It is indicated for use in oral, maxillofacial, cranial and spinal procedures; but is mainly used in orthodontics and craniofacial surgery. By adjusting the ultrasonic frequency of the device, it is possible to cut hard tissue while leaving soft tissue untouched by the process. The ultrasonic frequency is modulated from 10, 30, and 60 cycles/s (Hz) to 29 kHz. The low frequency enables cutting of mineralized structures, not soft tissue. Power can be adjusted from 2.8 to 16 W, with preset power settings for various types of bone density. The tip vibrates within a range of 60–200 µm, which allows clean cutting with precise incisions. Recent articles on the topic of piezoelectricity have named piezoelectric surgery ...

Osteodistraction
Distraction osteogenesis (DO), also called callus distraction, callotasis and osteodistraction, is a process used in orthopedic surgery, podiatric surgery, and oral and maxillofacial surgery to repair skeletal deformities and in reconstructive surgery. The procedure involves cutting and slowly separating bone, allowing the bone healing process to fill in the gap. Medical uses Distraction osteogenesis (DO) is used in orthopedic surgery, and oral and maxillofacial surgery to repair skeletal deformities and in reconstructive surgery. It was originally used to treat problems like unequal leg length, but since the 1980s is most commonly used to treat issues like hemifacial microsomia, micrognathism (chin so small it causes health problems), craniofrontonasal dysplasias, craniosynostosis, as well as airway obstruction in babies caused by glossoptosis (tongue recessed too far back in the mouth) or micrognathism. In 2016, a systematic review of papers describing bone and soft ...
