Evaluation of Maxillary Posterior Teeth Intrusion by Skeletally Anchored Mousetrap Appliance in Adult Patient With Anterior Open Bite.

Aim of the study: This clinical study aims to evaluate the dental, skeletal, and soft tissue effects of the Mousetrap appliance on the intrusion of maxillary posterior teeth in adult patients with anterior open bite. Material and methods: An uncontrolled clinical trial will be conducted involving 20 participants aged 15 to 27 years with skeletal Class I, II, or mild Class III relationships and a measured AOB of 3-8 mm. Participants will receive mini-implants inserted in the anterior palate, with the Mousetrap appliance designed to promote molar intrusion while maintaining vertical dimension. Intraoral scans, radiographs, and clinical photographs will be recorded at baseline and post-intrusion.
