Efficacy of Planas Direct Tracks for Early Treatment of Pseudo Class III Malocclusion: A Clinical and Cephalometric Study

Context: Anterior crossbite or pseudo Class III is one of such malocclusion which has potential to turn into facial deformity. Considering this, Planas direct tracks (PDTs) were selected to correct anterior crossbite. Aims To evaluate the efficacy of PDTs by studying pre- and post-treatment study models for correction in overjet and overbite and molar relationship.To evaluate cephalometrically, the treatment effect of PDTs on craniomaxillary and mandibular complex. Settings and design: A 6 months prospective cross-sectional study was conducted in the Department of Orthodontics and Dentofacial Orthopedics, Rural Dental College of Pravara Institute of Medical Sciences, Loni, from a period of April 2008 to October 2008. The total sample in the study consisted of seven subjects (3 males and 4 females) with a mean age of 5.3. Materials and methods: For all the subjects, all the diagnostic records were taken and maintained. The patient was immediately taken up for placement of PDTs in the oral cavity by indirect method. Statistical analysis used: Data was analyzed by applying student′s unpaired t-test at 5 and 1% level of significance. Results: Significant clinical change has occurred in all the subjects included in the study. There was significant reduction in the overbite and significant increase in overjet from negative to positive. The significant reduction in mesial step was observed. Cephalometrically, there was significant increase seen in the lower anterior facial height. There was significant change seen in inclination of upper and lower incisors. Significant change with lower lip was observed. Conclusion: PDT was an effective treatment modality for pseudo class III and anterior crossbite in early age.
