Objectives: This prospective study evaluated the accuracy of mandibular reconstruction using free fibular flaps (by comparing virtual plans to the three-dimensional postoperative results), and the extent of bone-to-bone contact after computer-assisted surgery. Methods: We included 65 patients who underwent partial-continuity mandibular resections from February 2013 to January 2017, and evaluated virtual planning, surgical techniques, and accuracy. Results: Forty-seven patients were analysed. A total of 112 fibular segments received 54 implants.

OBJECTIVES The aim of the present clinical case is to describe an orthodontic treatment to gain space in the maxillary arch by using a bone-anchored molar distalization appliance (distal-jet). Computer-guided palatal orthodontic mini-screws were inserted in the palatal vault thanks the use of a surgical guide realized with CAD/CAM technology. MATERIALS AND METHODS In this case report two orthodontic mini-screws were inserted in the palatal area by means of a surgical guide by a specialist in orthodontic without oral surgery or computer-guided skills.

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.
