Speedy Surgical Orthodontic Treatment With Skeletal Anchorage in Adults—Sagittal Correction and Open Bite Correction

Treatment outcome analysis of speedy surgical orthodontics for adults with maxillary protrusion

“…20 Frost's regional acceleratory phenomenon effect is, of course, also applied to corticotomy-facilitated orthodontics and speedy surgical orthodontics. [13][14][15][16][17][18]27,28 More specifically, after the speedy surgical orthodontics 3 to 6 months of the orthopedic retraction phase, the final phase of treatment is geared toward detailing the occlusion through conventional orthodontic forces and biomechanics. This orthodontic phase typically occurs in the regional acceleratory phenomenon's effective time frame, enabling the facilitated tooth movement.…”

“…15,16 The application of heavy forces in maxillary retraction was studied in an animal model with monkeys by Kawakami et al 19 and Yoshikawa 20 in Japan. They reported that a corticotomized maxillary segment could be effectively retracted using a heavy force of 400 g per side without damage to the intraoral or extraoral soft tissues, inferring that the orthopedic force after a perisegmental corticotomy could clinically apply to humans.…”

“…Expanding on the concept of Suya 11 to shorten conventional orthodontic treatment, Lee et al, 13 Chung et al, [14][15][16] Chung, 17 and Kanno et al 18 introduced the novel concept of "speedy surgical orthodontics," which involved a perisegmental corticotomy, a C-palatal miniplate, and a C-palatal retractor as key components in treating maxillary protrusion for adults. Although both speedy surgical orthodontics and corticotomyfacilitated orthodontics use a perisegmental corticotomy, in the former technique, the corticotomized bone block includes 6 maxillary anterior teeth instead of a single tooth.…”

“…More importantly, speedy surgical orthodontics can induce a bone-bending effect by applying the heavy orthopedic force against a palatal temporary skeletal anchorage device (Fig 1). 15,16,19,20 Recently, temporary skeletal anchorage devices such as orthodontic miniscrews and miniplates have replaced extraoral anchorage devices that rely significantly on patient compliance. [21][22][23] Advances in temporary skeletal anchorage device designs and applications have enabled orthodontists to use absolute anchorage and heavy forces without biomechanical side effects during orthodontic therapy.…”

“…24 This results in relatively faster tooth movement during the last stage of speedy surgical orthodontic therapy. Compared with the accelerated osteogenic orthodontics of Wilcko et al, 25 which rely primarily on Frost's regional acceleratory phenomenon to facilitate individual tooth movements during the total orthodontic therapy, the speedy surgical orthodontic technique of Chung [14][15][16][17] targets a dramatic change of tooth position by a perisegmental corticotomy and orthopedic bone bending followed by facilitated individual tooth movement. Although many studies have reported cephalometric evaluations of the various derivatives of surgically assisted orthodontic therapies, such as accelerated osteogenic orthodontics, corticotomyfacilitated orthodontics, anterior segmental osteotomy, and orthognathic surgery, few investigative efforts have qualitatively and quantitatively described the outcome of speedy surgical orthodontic treatment.…”
