WebbThe OBA has three palatal bars made of 1.5-mm round stainless steel wire. Palatal bars are 4-mm apart from the palatal mucosa. Palatal arches are bent on two layers of wax to avoid impingement to palatal mucosa during intrusion. Buccal bars are constructed using 0.8-mm round stainless steel wire. WebbThese loops correspond to the insertion sites for the MIs. This palatal wire arch is checked on the cast for correct transversal dimension and length (Fig. 29.1E). Two stop screws …
