Title

EFFECT OF BIONATOR TREATMENT ON SKELETAL AND DENTAL CHANGES IN CL II PATIENTS

Pages

  170-180

Abstract

 Introduction: One of the techniques to treat skeletal CL II MALOCCLUSION is growth modification. bionator functional appliance brings about skeletal changes to resolve CL II MALOCCLUSION caused by mandibular deficiency by protruding the mandible and accelerating growth. The aim of this study was to evaluate skeletal and dental changes in patients with CL II MALOCCLUSION following treatment with Bionator and to compare the results with the control group.Materials& Methods: The present clinical trial was carried out on 17 patients (8 girls and 7 boys) aged 9-11, with CL II MALOCCLUSION. To properly register the mandible, a wax rim was used and the bionator appliance was fabricated based on the recorded relationship in an arrticulator and delivered to the patients. Lateral cephalometric radiographs were taken before and after treatment. Tracing was carried out and the necessary measurements were made. Data were analyzed was paired t-test (a<0.05).Results: Comparison of mean changes in the antero-posterior cranial length, maxilla, and maxilla and mandible relative to each other between the bionator and control groups showed no significant differences between the two groups. The means of upper and lower gonial angles (p value=0.001), SNB angle, SN-pog angle, Y axis and pog-NP in the lower jaw showed significant differences between the control and bionator groups (p value=0.01. The mean of Pal-OCC angle, SNB angle, articular angle and Jarabak index (JI) (p value=0.01) of the facial relationship variables exhibited significant differences between the control and bionator groups.Conclusion: Bionator can be used to correct antero-posterior mandibular deficiency and Cl II skeletal and dental malocclusion during the growth period.
