Abstract

New digital technologies, many involving 3D printing, bring benefits for clinical applications. This article reports on the clinical procedure and CAD/CAM fabrication of a skeletally anchored mesialization appliance (“Mesialslider”) used for the space closure of a congenitally missing lateral incisor in a 12-year-old female patient. The insertion of the mini-implants and of the appliance was done in a single appointment workflow. The case report showed that bodily movement of the molars was achieved with the Mesialslider. Anchorage loss, such as a deviation of the anterior midline or palatal tilting of the anterior teeth was completely avoided. The CAD/CAM procedure facilitates the safe and precise insertion of mini-implants. Furthermore, they can improve patients comfort by reducing office visits and avoiding the placement of orthodontic bands or the taking of physical impressions.

Keywords: Agenesis, Orthodontic mini-implant, tooth movement, CAD/CAM
