Preliminary cone-beam computed tomography study evaluating dental and skeletal changes after treatment with a mandibular Schwarz appliance

3-Dimensional cone-beam computed tomography analysis of transverse changes with Schwarz appliances on both jaws

“…For example, the maxillary and mandibular first molar tipped approximately 8u and 8.7u, respectively, which was similar to our previous study. 19 A fixed RME appliance expands the nasal cavity width by an average 1.9 mm, but it widens it as much as 8-10 mm at the inferior turbinates, 20 while the more superior areas might move medially. 21 Increased nasal cavity width has important clinical implications with respect to nasal breathing because of increased permeability.…”

Cone beam computed tomography use in orthodontics

“…35,56 While all studies on rapid palatal expansion treatment demonstrated both dental and alveolar tipping, none found detrimental effects (such as dehiscences or fenestrations) to the alveolar bone supporting the posterior teeth. [57][58][59][60][61][62][63] CBCT images are clear enough to measure alveolar bone thickness to an accuracy of 0.6 mm. 64,65 In fact, one recent study suggested that CBCT images with a voxel size of 0.4 mm actually overestimate alveolar bone loss following rapid palatal expansion.…”

The nance lingual arch: an auxiliary device in solving lower anterior crowding

“…Other appliances could also be use to contribute to lower anterior crowding correction, such as lip bumper (15,16) and Schwarz appliance (17,18). However, they are not recommended in some cases for being removable appliances, thus depending on patient compliance.…”
