Using a Mousetrap Appliance to Intrude Maxillary Molars in Adults with Anterior Open Bite
Evaluation of Maxillary Posterior Teeth Intrusion by Skeletally Anchored Mousetrap Appliance in Adult Patient With Anterior Open Bite
NA · Mansoura University · NCT06757686
This study is testing if a special device can help move back upper back teeth in young adults with a specific bite problem to see if it improves their dental alignment.

What this trial studies
This clinical study evaluates the effects of a Mousetrap appliance on the intrusion of maxillary posterior teeth in adults with anterior open bite. The trial will involve 20 participants aged 15 to 27 years who will receive mini-implants inserted in the anterior palate to facilitate the treatment. The study will assess dental, skeletal, and soft tissue changes through intraoral scans, radiographs, and clinical photographs taken before and after the intrusion process. The Mousetrap appliance is designed to promote molar intrusion while maintaining the vertical dimension of the teeth.
Who should consider this trial
Good fit: Ideal candidates are healthy adults aged 15 to 27 years with skeletal Class I, II, or mild Class III relationships and an anterior open bite of 3-8 mm.
Not a fit: Patients with moderate to severe Class III skeletal relationships or those with periodontal issues may not benefit from this study.
Why it matters
Potential benefit: If successful, this approach could provide a novel orthodontic solution for adults with anterior open bite, improving their dental alignment and function.
How similar studies have performed: While the specific Mousetrap appliance approach may be novel, similar methods of using skeletal anchorage for molar intrusion have shown promise in previous studies.
Eligibility criteria
Show full inclusion / exclusion criteria
Inclusion Criteria: * Age ranging from 15 to 27 years. * High angle patients with skeletal Class I, II or mild Class III. * Patients with anterior open bite requiring maxillary posterior teeth intrusion as part of orthodontic treatment. * Anterior open bite: range from 3-8 mm. * Healthy adult patients. * No previous orthodontic treatment. * No evidence of either periodontal problems, gingival problems, or bruxism, at the beginning of orthodontic treatment. * No medical problems interfering with orthodontic treatment. Exclusion Criteria: * Moderate to severe Class III skeletal relationship patients were excluded, as the molars intrusion would lead to increase the severity of Class III malocclusion. * Patient with bad oral hygiene. * Periodontal problems.
