ESPINAL-BOTERO, Gabriel et al. Condylar changes by Planas Indirect Compound Tracks on Class II malocclusion evaluated with Cone Beam. CES odontol. [online]. 2015, vol.28, n.2, pp.47-57. ISSN 0120-971X.

Abstract Introduction and objective: In malocclusion class II, a treatment option is the alteration of mandibular growth through the use of functional orthopedic appliances.To describe the changes in the condylar morphometry and morphology and clinical changes after a year of use of Planas Indirect Compound Tracks (PIPC) in patients with class II malocclusion. Materials and methods: Through tomography CT Cone - Beam and clinical reviews were assessed 8 patients with ages between 7 and 10 years, before (T1) and after a year (T2) the use of PIPC, describing changes in condylar morphology and morphometry in planes axial, coronal and sagital, as well as dental clinical changes. Results: Measurements right and left latero-medial in the axial cut and right latero-medial in the coronal cut showed statistically significant differences (p < 0,05) between T1 and T2. In the sagital cut the predominant form was the rounded 100% in both condyles before and after treatment. Clinical analysis the overjet decreased 2.88 ± 1.51 mm with the use of the appliance. Conclusions: In this study we observed that the condylar morphology was bilaterally symmetrical in all courts. After a year of treatment with Planas Indirect Compound, increased bilateral dimension latero medial condyle (morphometric changes ), decreased overjet and the overbite was observed , no changes were observed in the condylar morphology. According to these results, Planas Indirect Compound Tracks can be an alternative treatment for Class II malocclusion.
