Title : The evaluation of the indirect skeletal anchorage in combination with class II elastics for treating class II malocclusion.

Abstract :

Intermaxillary elastics is used as a therapeutic method for treatment of the skeletal class II malocclusion because of its skeletal and dentoalveolar effects similar to those of functional appliances. However, the dental side effects prompted researchers to strenghthen the anchorage in order to overcome these side effects, especially after the spread of skeletal anchorage devices. The aim of this study is to evaluate the skeletal and dentoalveolar changes resulted from using class II intermaxillary elastics in combination with indirect skeletal anchorage. The sample consisted of 17 growing patients with skeletal class II malocclusion caused by mandibular deficiency. They would have permanent dentition or at the end of mixed dentition. All the patients treated with Class II elastics supported by miniscrews indirectly. cephalometric radiographs were taken just before and after mandibular advancement (T1 and T2 respectively). It was found by studying cephalometric radiographs that using class II elastics in combination with indirect skeletal anchorage by miniscrews caused forward movement of the mandible and increasing in its length. It also resulted an acceptable proclination of lower incisors and extrusion of the lower molars.
