Abstract
Angle Class II division 1 malocclusion has been one of the most encountered problems in the orthodontic practice. In growing patients, mandibular repositioning appliances are the method of choice to induce mandibualr growth and are termed functional appliances. This study was carried out to evaluate the possible effect of the Sabbagh Universal Spring2(SUS2) on the dental and skeletal cephalometric measurements in the permanent dentition of ten growing patients of both genders with Class II division 1 malocclusion and to compare its effect with the similar available data of similar fixed functional appliances. It was concluded that The Sabbagh Universal Spring2 appliance works well with the treatment philosophy of Class II division 1 malocclusion with retruded mandible by advancing the mandible anteriorly.
