Treatment of unilateral buccal crossbite with mandibular symphyseal distraction osteogenesis

Abstract

The aim of this report is to present the treatment of a 14-year-old boy with scissors-bite. Mandibular symphyseal distraction osteogenesis (MSDO) with tooth-supported distractor was performed to expand the mandible, and intermaxillary cross elastics were used. The mandible was expanded approximately 9 mm. Asymmetric widening was done by using cross elastics and MSDO simultaneously. The buccal crossbite was corrected successfully. After a 2-year observation period, widening of the mandible using this procedure was judged to be stable. (Korean J Orthod 2011;41(1):59-69)

Unilateral Posterior Crossbite - Shoot It At Sight. A Review

“…Although it has several advantages, the surgeon must be careful because it could cause periodontal defects or ankylosis of the involved teeth if excess osseous tissue is removed or injuring the periodontal ligament. This also can cause phonetic problems and TMJ disorders (10) .…”

Three‐dimensional analysis of mandibular morphology asymmetry and temporomandibular joint position in patients with unilateral Brodie bite

“…6 Previous case reports have indicated that some patients with unilateral Brodie bite may suffer from temporomandibular joint disorders (TMD) 7 and facial asymmetry. [8][9][10][11][12] The condylar position and morphology were also suggested to be different in several cases of unilateral Brodie bite. 9,10 Accordingly, we hypothesized that unilateral Brodie bite might be correlated with the mandibular morphology and position in patients with unilateral Brodie bite.…”

“…It is worth noting that unilateral scissors‐bite can be asymptomatic initially and compromised by chewing on the healthy side 6 . Previous case reports have indicated that some patients with unilateral Brodie bite may suffer from temporomandibular joint disorders (TMD) 7 and facial asymmetry 8–12 . The condylar position and morphology were also suggested to be different in several cases of unilateral Brodie bite 9,10 .…”
