Finite model analysis of different anchorage sites for bone-supported facemask application in unilateral cleft lip and palate.
Am J Orthod Dentofacial Orthop

Department of Orthodontics, Faculty of Dentistry, Hacettepe University, Ankara, Turkey. Electronic address:
Introduction: The objective of this study was to evaluate the effects of the miniplate application sites in the maxilla and the applied force vector changes during skeletally supported facemask application in adolescent patients with unilateral cleft lip and palate (UCLP) using finite element model (FEM) analysis.
Methods: A FEM was obtained from a cone-beam computed tomography image of a 12-year-old female patient with UCLP. Miniplates were placed on 3 different sites of the maxilla; 500 g of advancement force was applied bilaterally, parallel (0°), and downward (-30°) to the occlusal plane.
Adaptation of virtual surgical planning to midface reconstruction with intraoperative navigation: "navigation mediated midface reconstruction".

Department of Biomedical Engineering, Ankara University, Ankara, Turkey.
Objective: The production of 3-dimensional models and materials according to preoperative virtual surgical planning is a time-consuming process and causes high costs. We aimed to demonstrate the navigation mediated reconstruction of the patients who underwent the removal of a tumoral mass in midfacial region according to their preoperatively prepared surgical plannings.
Study Design: Patients who underwent the removal of tumoral mass and reconstruction in their midfacial region were included in the study.
Secondary Reconstruction of Premaxilla With a π-Shaped Fibula Osteocutaneous Flap.

Department of Plastic and Reconstructive Surgery, The University of Tokyo.
Midface deformities due to oncologic bony defects are often difficult to secondarily correct. The authors herein report 2 cases of secondary reconstruction of an oncological premaxillary defect using a π-shaped fibula osteocutaneous flap. The authors divided the fibula into 3 pieces and made it π-shaped to reconstruct the curvature of the premaxilla.

Private Practice, Guilford, CT.
Objective: Profileplasty traditionally involves improving a nasal hump or an underprojected chin. However, this procedure can correct other facial defects like saddle nose or prognathism. To establish the best overall profile, the nose, the midface, and the chin should be considered altogether.

Department of Orthodontics, Faculty of Dentistry, Pontificia Universidad Católica de Chile, Santiago, Chile.
Background: The premaxillary-maxillary suture (PMS) is related to midface development, but its exact closure period remains undefined. Some authors consider the premaxilla as an independent bone with potential for orthopaedic stimulation, while others see it as a phylogenetic vestige.
Objective: To determine the prevalence of the premaxillary-maxillary suture (PMS) in cone beam computed tomography (CBCT) images of patients aged 6 to 16years, according to age and sex, treated at the Dental Clinic of the Pontificia Universidad Católica de Chile's Oral Imaging Service between 2015 and 2023.
