Static computer-assisted surgery (s-CAS) has been introduced to improve the results of implantology. A prospective cohort study was conducted following the STROBE guidelines to determine the presence of a learning curve in s-CAS. Six partially and six totally edentulous patients were treated by two surgeons experienced in implantology but completely inexperienced in s-CAS. Preoperative and postoperative computed tomography scans were matched to assess coronal, apical, and angular deviation and the positioning error. The accuracy data were used to evaluate the learning curve.

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.

Introduction: The primary aim of this study was to investigate and compare perceived pain intensity and oral health–related quality of life (OHRQOL) results during the activation phase of rapid maxillary expansion (RME), with tooth-borne and bone-borne devices. In addition, a secondary aim of this study was to evaluate the correlation between pain scales and the shortened Oral Health Impact Profile (OHIP-14) questionnaire. Methods: Thirty-six subjects (16 girls and 20 boys) with a mean age of 12.3 years (standard deviation, 0.82 years) were randomized into 2 groups.
