Treatment of maxillary deficiency by miniscrew implants – a case report

Abstract

This case report illustrates the treatment of a 12-year-old boy with maxillary deficiency using miniscrew implants. The patient rejected the use of extraoral appliances and future surgical correction; therefore the patient was treated using Class III elastics connected from two mandibular miniscrew implants to an upper removable appliance. The miniscrews were inserted between the permanent canines and first premolars under local anaesthesia. The treatment lasted for 8 months after which favourable correction of the malocclusion was observed. The SNA and ANB angles increased by 3 degrees and the IMPA increased by 4 degrees . This case demonstrates that miniscrews can be a suitable alternative method to extraoral appliances and possibly surgery in mild Class III cases.
