“…If the premaxilla is elongated over the occlusal plane, intrusion of the front segment would be therapeutically indicated. However, if the anterior lateral segments are pivoted in the cranial direction [38], the bite should be raised by extruding the lateral segments. This is quite important, since the vertical deviations we observed seem to occur regardless of how and when the cleft palate is closed [10].…”

“…According to Töndury [36], the failure of the palatine, medial and lateral nasal processes to fuse results in the forward displacement of the premaxilla and hence to the collapse of the lateral maxillary segments in the anterior region towards the middle and upwards. Transversal underdevelopment of the anterior maxilla is just as much a consequence thereof as is the anterior rotation of the alveolar processes [38].…”

“…Durch das Ausbleiben der Verschmelzung der Gaumenfortsätze sowie der medialen und lateralen Nasenwülste kommt es nach Töndury [36] zum Ausweichen des Zwischenkiefers nach vorn und so zum Kollaps der lateralen Kiefersegmente im anterioren Teil zur Mitte hin und nach oben. Eine transversale Unterentwicklung der anterioren Maxilla ist ebenso die Folge wie eine anteriore Rotation der Alveolarfortsätze [38].…”

Bone-anchored maxillary protraction in patients with unilateral complete cleft lip and palate and Class III malocclusion

Objective This prospective controlled study evaluated the effect of bone-anchored maxillary protraction therapy in cleft children with Class III malocclusion using CBCT-derived 3D surface models. Materials and subjects Eighteen cleft patients between 10 and 12 years old were included. Intermaxillary elastics were worn after the placement of four zygoma bone plates for 18 months. Uniquely, three age-matched untreated groups including both cleft subjects and non-cleft subjects with Class III malocclusion served as controls. Profile photos and CBCT scans for each patient were taken before (T0) and 18 months after the protraction (T1). 3D measurements were made on CBCT surface models from the treatment group using tomographic color mapping method. Cephalometric measurements were made on lateral cephalogram reconstructed from the CBCT scans and were compared with those obtained from the control groups. Results Two thirds of the treatment subjects showed improved lip projection towards more convex facial profile. The most significant skeletal changes on 3D surface models were observed at the zygomatic regions (mean 1.5-mm forward, downward, and outward displacement) and at the maxillary complex (mean 1.5-mm forward displacement). Compared with the control groups, the treatment subjects showed significant increase in the SNA and ANB angles, increased Wits appraisal, a more forward movement of point A and overjet improvement (p < 0.05). Conclusions BAMP in cleft patients gives a significant forward displacement of the zygomaxillairy complex in favor of the Class III treatment. Clinical relevance This treatment method shows clearly favorable outcome in cleft patients after 1.5 years of BAMP.
