Maxillo-mandibular reconstruction in pediatric patients involves particular functional and cosmetic implications. Attention is required for the craniofacial growth over time, involvement of the permanent dentition, facial symmetry, and donor site morbidity. Our aim is to identify the best reconstructive options for maxilla-mandibular defects in children (<18 years) based on our experience with 25 pediatric patients. We believe that reconstruction has to be performed at the same time as resection in pediatric patients.

Aim: To present a minimally invasive approach to solve the impaction of palatal canines using computer-guided orthodontic miniscrews. Materials and methods: Miniscrew-supported appliances for palatal canine disimpaction are performed with CAD/CAM technology. With adequate software, it is possible to match the STL files of the dental arch with the DICOM images of the maxilla, previously transformed into STL files. The ideal points for miniscrew insertion can be identified on the STL 3D model file on the basis of the width and thickness of the palatal vault.

Background: An observational case-control study was designed to retrospectively assess the association among sex, skeletal and dental variables and the and the palatal maxillary canine impaction. Methods: The STROBE guidelines were followed. The records of 2195 subjects were analyzed. The data records of subjects with palatally displaced canine (PDC) were compared with the data of randomly selected subjects without PDC. Descriptive statistics, logistic regression model and χ2 test were used.
