Analysis of orthopedic treatment of skeletal Class III malocclusion with Rapid Palatal Expansion and Face Mask therapy

Abstract

Aim: To demonstrate the main effects on maxillary and facial profile after treatment with expansion and face mask therapy in patients pattern III Class III. Material and Method: A cross-sectional study of maxillary expansion and reverse traction performed in 4 patients with maxillary deficiency, in the pre-peak pubertal growth stage and in the mixed dentition, with cephalograms before and after treatment, using angular measurements (SNA, SNENA, ANL and 1NA) and linear (S’-ENA, S’-A, 1-NA, OVERJET, S-LS and S-LI) and plot overlays. Results: Improvement in overjet was observed, going from negative to positive in all cases treated with incisor uncrossing, although it was not statistically significant. The upper and lower labial posture with respect to the base of the nose and the ment improved significantly, represented by the measurements S-LS and S-LI, with a change from the concave profile to slightly convex. Conclusion: Class III malocclusion with maxillary deficiency treated with rapid maxillary disjunction and reverse traction with facial mask was effective in both groups, with maxillary protraction and shifting in the concave to slightly convex profile.KeywordsFacial Mask; Rapid maxillary expansion; Class III.

Multidisciplinary action in a patient with cleft lip and palate: esthetic-functional dentofacial treatment for more than two decades

“…Orthodontic intervention is performed at different multidisciplinary treatment stages; a pre-surgical orthodontic approach is required in the early stages [9][10][11], and then the postsurgical orthodontic treatment is continued. At this point, it can be determined whether the patient's malocclusion can be treated with conventional orthodontic treatment, or whether another orthognathic procedure such as maxillary advancement will be necessary [1].…”
