Evaluation of Skeletal Stability After Surgical–Orthodontic Correction of Skeletal Open Bite With Mandibular Counterclockwise Rotation Using Modified Inverted L Osteotomy

Allogeneic Bone Graft for Stability of Inverted L Osteotomy Mandibular Ramus

“…In a study [4] with 12 patients who underwent counterclockwise rotation of the mandible for correcting anterior open bite through modified inverted 'L' osteotomy, results showed good long-term stability. The authors concluded that, when the maxilla is well positioned, correcting anterior open bite with mandibular counterclockwise rotation is a good option.…”

Surgery First

“…[14][15][16] The design has a buccal step laid adjacent to the mandibular second molar area. 12,13 Therefore other SF groups must apply more invasive two-jaw surgery in order to avoid the increase in posterior facial height. 22-6).…”

Mapping the Mandibular Lingula in Pierre Robin Sequence

“…[4][5][6][7][8][9][10] Furthermore, tooth root injury can occur during osteotomy, placement of screws/pins, or application of distraction forces, potentially causing changes in the mandibular molars, destruction of tooth follicles, altered dental development, long-term tooth loss, and dentigerous cyst formation. [11][12][13] In comparison, proponents of the inverted-L ramus osteotomy (ILRO), first described in 1927 by Wassmund, 10,14,15 and subsequently modified by others, [16][17][18][19][20] have championed the technique for avoiding injury to tooth roots and the inferior alveolar nerve. 19,[21][22][23] Furthermore, other advantages of the ILRO 21 include increased posterior facial height, 24 preserved position and retained balance of masticatory muscles, 23 and increased osseous stabilization.…”
