What this Trial Is About
Researchers are evaluating the effects of the Mousetrap appliance, a skeletally anchored device, on the intrusion of maxillary posterior teeth in adults with anterior open bite. This clinical study focuses on dental, skeletal, and soft tissue changes in patients aged 15 to 27 years who have skeletal Class I, II, or mild Class III relationships and an anterior open bite measured between 3 and 8 mm. The study is an uncontrolled clinical trial designed to better understand this orthodontic treatment approach. Participants will receive two mini-implants inserted into the anterior palate under topical and/or local anesthesia. The Mousetrap appliance, which includes lever arms connected to the mini-implants and a transpalatal arch to prevent molar tipping, will be placed and activated using power chains. Customized digital designs ensure the appliance fits with enough clearance to avoid irritation. Intraoral scans, radiographs, and clinical photographs will be taken before insertion and after molar intrusion. During the study, participants will undergo baseline and post-intrusion assessments including intraoral scans and imaging to monitor changes. The main outcome measured is the amount of molar intrusion over six months. Researchers will also track dental, skeletal, and soft tissue effects. The total study duration and safety monitoring details are based on these assessments to evaluate the appliance's impact on anterior open bite correction.
