TAD - intrusion of the posterior maxillary molars - mild to moderate open bite cases

Recently, the minimally invasive placement of TADs (temporary anchorage devices) has allowed orthodontists to treat some of these patients without orthognathic surgery through intrusion of the posterior maxillary molars. While TADs are not a substitute for surgery in all cases, they do provide a treatment alternative for specific mild-to-moderate open bite cases without other skeletal malformations.
