title: Jefferson skeletal classification system (JSCS) and how it helps in extraction and non-extraction orthodontic cases.
abstract: Facial appearance depends mainly on bone support 1,2,3,4,5. Bone position is the first consideration when making an orthodontic treatment decision. The skeletal classification evolved to give us the opportunity for a better assessment and understanding of cases. Jefferson Skeletal Classification System (JSCS) shows the most common malpositioned jaws. This system will also help to asses extraction and non-extraction orthodontic cases.
