Orthopaedic Protraction of the Maxilla with Miniplates: Treatment of Midface Deficiency

Abstract

Class III malocclusion is a consequence of maxillary deficiency and/or mandibular prognathism, resulting in an anterior crossbite and a concave profile. Early class III malocclusion treatment with reverse pull headgear generally results in maxillary skeletal protraction but is frequently also accompanied by unfavourable dentoalveolar effects. Titanium miniplates used as temporary anchorage device might permit equivalent favourable skeletal changes without unwanted dentoalveolar effects. We report two cases having class III malocclusion with maxillary deficiency treated by using titanium miniplates. Cephalometric tracings were done pre and post treatment to determine the anatomic changes during the course of treatment.

“…Class III malocclusion can be treated by several different means depending on the diagnosis and age of the patient. During adolescence, orthopaedic growth modification such as chin cup therapy and reverse‐pull facemask therapy can be considered as well as a new technique involving bone‐anchored maxillary protraction plates …”

“…During adolescence, orthopaedic growth modification such as chin cup therapy 9 and reverse-pull facemask therapy 10 can be considered as well as a new technique involving bone-anchored maxillary protraction plates. 11 Dental Class III can commonly be treated with full fixed appliances and elastic wear 12 with or without interproximal reduction. 13 Orthognathic surgery, while often thought of as a "last resort," can in fact be the only reasonable option in a case with a severe skeletal imbalance and compromised facial aesthetics.…”
