The loss of anterior teeth leads to extreme psychological trauma, along with functional and esthetic debilitations. Healthy anterior teeth play an important role of protecting the posterior teeth during excursive mandibular movement. Loss of anterior teeth induces posterior interference with extended disocclusion time. Posterior disocclusion is critical to remove the harmful force on the teeth ...

Mechanics using a mid-palatal temporary anchorage device (TAD) and an intrusion transpalatal arch (TPA) were applied to correct the open bites. Two different patterns could be obtained according anteroposterior position of TADs. When TAD was placed posterior first molar, teeth intruded (“posterior intrusion”), bite corrected efficiently. This is commonly used in most However, sometimes, with gu...

A 17-year-old female presented with the chief complaint of inability to bite properly.
