Summary

This randomized clinical trial aims to compare the effectiveness and patient acceptance of two orthodontic appliances-conventional palatal crib and bonded spurs-in the treatment of anterior open bite in children.Twenty children aged 7 to 12 years with anterior open bite and Class I skeletal and dental relationships will be randomly assigned to one of two groups The first group will receive a conventional palatal crib appliance fixed to the upper molars, while the second group will receive bonded spurs attached to the palatal surfaces of the upper incisors , All participants will be followed for 6 months. Clinical and digital measurements, including overbite ,The results of this study are expected to help determine which appliance provides better clinical outcomes and higher patient acceptance in the early treatment of anterior open bite.

Conditions

  • Anterior Open Bite

Interventions

DEVICE

Conventional Palatal Crib

A fixed orthodontic appliance made of 0.9 mm stainless steel wire with 5-7 loops and an acrylic button covering the base.It is cemented to the maxillary first molars using Ultra band cement and positioned 3-4 mm posterior to the cingula of maxillary incisors to prevent tongue thrusting. Treatment duration is 6 months.

DEVICE

Bonded Spurs

Bonded spurs are placed on the middle third of the palatal surfaces of the maxillary and mandibular incisors. They correct anterior open bite by preventing the tongue from contacting the upper and lower anterior teeth and reminding the patient to maintain proper tongue position. Treatment duration is 6 months.
