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

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

Sponsor

Mansoura University

Enrollment

20 participants

Start Date

Aug 25, 2024

Study Type

INTERVENTIONAL

Conditions

Maxillary Molar Intrusion

Summary

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.

Eligibility

Min Age: 15 YearsMax Age: 27 Years

Inclusion Criteria8

  • 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 Criteria3

  • 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.
