Non-Osteotomy Treatment of Class III Skeletal Malocclusion Using Bollard Plates

A total of 14 patients were enrolled in the study at cervical vertebral maturation stage CVM2. Bilateral FDA approved miniplates (Bollard plates) were surgically inserted in the infrazygomatic crests of the maxilla and between the canine and the lateral incisor in the anterior mandible. The patients were treated by intermaxillary elastics for an average of 16 months. Cephalometric analysis was done before, during and at the end of the treatment. Intraoral and extraoral photographs were taken for comparisons. In this study, we analyze the effect of maxillary advancement in patients with class III skeletal malocclusions using a nonosteotomy technique that produces combined maxillary advancement and mandibular retraction using bone anchored Bollard plates (Tita-Link, Brussels, Belgium). We evaluate the change in WITS appraisal and ANB values for each patient before and after treatment. OMaxillary hypoplasia is frequently found in Class III Malocclusion patients O Traditional Treatment options include use of protraction face mask anchored to dentition or a more invasive Le Fort osteotomy OBone Anchored Maxillary Protraction devices provide skeletal anchorage O Requires active sutures in growth phase, skeletal anchorage buttress and remodeling of adjacent bone OLess invasive than osteomies
