Retreatment of Class II malocclusion with uncontrolled loss of anchorage by miniscrews and sliding jigs: A case report

The incorporation of miniscrews into orthodontic eld has allowed for more predictable anchorage control and increased the ability to correct severe skeletal and dental discrepancies. In addition to that, many of orthodontic cases with uncontrolled loss of anchorage became more reversible cases and the possibility for retreating them has increased with miniscrews. This case report describes upper molar distalization by the use of miniscrews and sliding jigs to retreat Class II malocclusion case with uncontrolled loss of anchorage. The use of sliding jigs supported by miniscrew in this case was helpful in distalization of upper molars and treatment of uncontrolled loss of anchorage
