Surgically Facilitated Orthodontic Therapy (SFOT) in combination with bone augmentation and the placement of anchorage devices installed into bone have been used to accelerate and facilitate orthodontic treatment. This is usually performed after flap surgery, which is associated with moderate morbidity, as well as possible negative sequale such as gingival recession. The present case report illustrates the clinical benefits of vestibular incision subperiosteal tunnel access (VISTA) for SFOT, and tissue augmentation to facilitate orthodontic therapy. VISTA entails making vertical incision(s) in the vestibule followed by subperiosteal elevation of tunnels to provide direct access to the facial alveolar bone. Unlike previously reported vestibular access surgical procedures, VISTA allows for wider elevation of an access tunnel for clear visual and surgical access to perform careful inter-radicular corticotomy. The present report describes VISTA for corticotomy surgery (anterior mandible and maxillary teeth) in combination with the placement of titanium fixation devices and bone augmentation to facilitate orthodontic treatment of an adult female with borderline Class II Division 1 malocclusion, with excessive overjet and deepbite. In view of the fact that VISTA does not require surface incisions in the gingival margins or papillae, it potentially minimizes gingival recession that sometimes accompanies flap surgery.
外科辅助正畸治疗（SFOT）结合骨增量和植入骨内的锚固装置已被用于加速和促进正畸治疗。这通常在翻瓣手术后进行，翻瓣手术会带来中度的发病率，以及可能的负面后遗症，如牙龈退缩。本病例报告阐述了前庭切口骨膜下隧道入路（VISTA）用于SFOT以及组织增量以促进正畸治疗的临床益处。VISTA需要在前庭做垂直切口，随后进行骨膜下隧道剥离，以直接进入牙槽骨面部。与先前报道的前庭入路手术不同，VISTA允许更广泛地剥离入路隧道，以便清晰地进行视觉和手术操作，从而仔细地进行牙根间皮质切开术。本报告描述了用于皮质切开术（下颌前部和上颌牙齿）的VISTA，结合钛固定装置的放置和骨增量，以促进对一名患有临界II类1分类错牙合、前牙深覆盖和深覆牙合的成年女性的正畸治疗。鉴于VISTA不需要在牙龈边缘或乳头处做表面切口，它有可能将有时伴随翻瓣手术的牙龈退缩降至最低。
