Maxillary protaction with zygomatic anchorage in a growing class III patient

Abstract

Summary Maxillary protraction headgear with dental anchorage is commonly used in the treatment of class III malocclusion, but this treatment has been shown to have certain undesirable effects such as the loss of dental anchorage. These side effects can be reduced with the use of skeletal anchorage such as miniplates, mini screws and implants. This case report describes an orthopaedic treatment performed on a 10-year-old boy presenting a class III malocclusion with maxillary hypoplasia, for which a 10-month first phase of maxillary protraction was realised with zygomatic miniplates used as a skeletal anchorage. As a result, significant skeletal, dental and facial changes were observed.
