Maxillary Corticotomies With Bone-to-Bone Retraction and Mandibular Segmental Osteotomy for Correcting an Anterior Double Protrusion

Abstract

A combination of maxillary corticotomies with skeletal anchorage for bone-to-bone retraction and a mandibular ASO under local anesthesia might be an alternative treatment option for excellent profile change in a short treatment period.

Clinical Application and Biomechanics of Various Lingual Retractors with Temporary Skeletal Anchorage Devices: A Narrative Review

“…An anterior lingual arch (connecting wire) is fabricated along the lingual surface of the six anterior teeth with a 0.032-inch or 0.036-inch stainless steel (SS) wire and soldered to the anterior attachment pad. The two lever arms are placed on both canines [10][11][12]25,26] or between the central and lateral incisor [2,9,[27][28][29][30], such that the force passes close to the CR of the anterior teeth and the fabricated retractor is bonded to the lingual surface of the anterior teeth. (Figure 1) To reinforce intra-arch anchorage, a transpalatal arch (TPA) with soldered hooks is fabricated with a 0.032-inch or 0.036-inch SS wire on both the first and second molars (Figure 2a) [1,11,12,25].…”

When absolute anchorage is required during retraction of the anterior teeth, TSADs, such as miniscrews (Figure 2b) or C-palatal plates (Figure 2c, Jin Biomed, Bucheon, South Korea) are inserted in the palatal area [1][2][3]9,27,29,30]. Since the appliances are not bonded to the posterior dentition when using the CLR with TSADs, the CLR is useful when the occlusion of the posterior dentition is normal and movement of the posterior teeth is desired to be minimal.…”
