CAD-CAM Workflows for Palatal TAD Anchored Appliances

Mini-implants inserted in the anterior palate are showing the very high success rates of 91.5% - 99%. Compared to other insertion sites, they can be used effectively for molar distalization, space closure, rapid maxillary expansion and protraction, molar intrusion and alignment of impacted upper teeth. In recent years, CAD-CAM techniques such as printed insertions guides and 3D metal printing were integrated into full digital workflows. These new procedures allow mini-implant insertion and appliance fitting in one appointment and may give orthodontists more confidence to insert in the optimum site. Additionally, the CAD/CAM design process may offer the opportunity to further improve orthodontic appliances biomechanically.
