ABSTRACT

Rapid palatal expansion(RPE) with the tooth-born appliance is not sufficient to apply to the patients with periodontal problem or insufficient tooth anchorage, and it leads to tipping of the anchorage teeth and increasing teeth mobility and root resorption. To avoid these disadvantages, we present the case using palatal screws and custommade palatal expander. A 23-year-old patient underwent surgically assisted rapid maxillary expansion with the Hyrax expansion using 4 tent screws. The study models were used to measure the pre-/-post surgical width of the anterior and posterior dental arches with a digital sliding caliper. In the result, the custom-made palatal expander with 4 tent screws is suitable for delivering a force to the mid-palatal suture expansion. And it is low cost, small sized and simply applied. The results indicated that maxillary expansion with the custom-made palatal anchorage device is predictable and stable technique without significant complications in patients.

ABSTRACT

Patients who have repaired cleft lip and palate generally undergo restriction of maxillary growth. Concave facial profile is often exhibited with relatively normalized mandible. Horizontal and sagittal deficiency of the maxilla could cause anterior and posterior crossbites. In growing patients, orthodontic and orthopedic treatment is acceptable with maxillary expansion and protraction. However, surgical approach has to be accompanied with orthodontic treatment in skeletally matured patients. We used SARPE and BSSRO to expand the constricted maxilla and retract the mandible in a patient who had cleft palate repaired in infancy. Through SARPE, orthodontic treatment and BSSRO, we sufficiently expanded the maxillla and improved facial profile.
