A novel active intraoral appliance for presurgical orthopaedic treatment in patients with complete bilateral cleft lip and palate

摘要

Background: Management of the protruding/deviated premaxilla in patients with complete bilateral cleft lip and palate is a challenging problem for surgeons and orthodontists. Various passive and active methods have been developed for the presurgical orthopaedic treatment. However, most of these treatments are complicated and laborious for the patient's parents and clinicians. Here, we describe our original active intraoral appliance comprising two components, that is, the premaxillary and palatine process plates, connected with two elastic chains, and we assess its therapeutic efficacy.
