Computer-aided design and manufacturing of bone- and tooth-borne maxillary protraction with miniscrews and Class III elastics: Can we contemporize Class III treatments in growing patients?

The purpose of this clinical report is to illustrate an innovative treatment plan for a patient with Class III malocclusion. The plan combined the versatility of computer-aided design and manufacturing technology with miniscrews. Maxillary and mandibular fully customized metal framework anchored to 4 miniscrews was digitally designed and constructed for a growing patient with midface hypoplasia and a skeletal Class III malocclusion. The patient wore Class III elastics between hooks on the maxillary and mandibular frameworks full time for 10 months. Overcorrection was obtained with limited dental side effects, and a significant improvement of the profile was achieved. With the advantages of computer-aided design and manufacturing technology and less invasive insertion procedure compared with miniplate surgery, this patient-specific treatment approach was simple and effective.
