title: [SGTB orthopedic regime to correct protrusive skeletal anomalies: a developmental path through evolution, renovation and innovation].
abstract: Sagittal-guidance Twin-block appliance (SGTB), an orthopedic therapy that has been widely implemented in orthodontic practice since it was introduced by the author a decade ago. This overview was aimed to clarify the fundamental mechanism of SGTB in correction of skeletal malocclusions, i.e., retraction of the maxilla triggered by the muscular force generated from mandibular forward positioning. This overview was also designed to summarize the evolutionary pathway through which SGTB regime originated and developed from removable, bonded and to the latest form of clear aligner SGTB. It was concluded that SGTB promised to be an efficient orthopedic approach to manage complicated and severe dentofacial anomalies with skeletal element.
