We present the treatment of an injured and avulsed incisor (which was afterwards ankylosed), by subapical osteotomy and conventional orthodontic mechanisms. A 9-year-old boy presented for orthodontic treatment with an injured and avulsed central incisor, which, after initial repositioning, ended up with ankylosis and severe root resorption. The case was treated by single tooth alveolar osteotomy and distraction osteogenesis through conventional orthodontics, advocating for the floating bone concept due to the short vertical distance by which the tooth alveolus part had to be relocated. Orthodontic treatment of the avulsed central incisor was completed after osteotomy and distraction osteogenesis, and the tooth was restored to its proper position, aiming to address issues of aesthetics and function for the time being. The patient was finally referred to a prosthodontist for future and final implant rehabilitation due to severe root resorption. Distraction osteogenesis after surgical procedures is a reliable solution for dealing with an ankylosed and submerged tooth.

The aim of this study was to explore the factors influencing the quality of new bone formation after distraction osteogenesis in children with Pierre Robin sequence (PRS). Using cone-beam computed tomography (CBCT), bone density relative grayscale values of the region of new bone formation before and 3 to 4 months after mandibular distraction osteogenesis (MDO) were measured in 80 children with PRS, and correlation analysis was conducted with the potential clinical influencing factors of the children. CBCT reconstruction of the panoramic film showed that the new bone formation was good at 3 to 4 months after MDO.

Purpose: Ollier's disease (multiple enchondromatosis) can cause severe lower limb length discrepancy and deformity in children. Osteotomy and limb lengthening with external fixation can correct the lower extremity deformity. There may be lesions in the osteotomy part (OP), and the internal fixation part of the external fixation(FP).

Objective: The surgical management of craniosynostosis varies without consensus on technique or standard outcomes reporting. The authors of this study aimed to investigate current surgical management of craniosynostosis in the United States.
Methods: Two hundred seventy-five surgeons actively treating craniosynostosis in the United States were surveyed.

Background: The purpose of this study was to report the clinical and psychological outcomes of using a locking compression plate (LCP) as a sequential external fixator following the distraction phase in the treatment of tibial bone defects caused by fracture-related infection (FRI).
Methods: We retrospectively analyzed the clinical records and consecutive X-ray images of patients with tibial bone defects who were treated with an LCP as a sequential external fixator following the distraction phase, between June 2017 and December 2022. The ASAMI criteria were applied to assess the bone and functional outcomes, and postoperative complications were evaluated by using the Paley classification.
