Details and patient eligibility

About

Comparing between the failure rates of molar tubes bonded with conventional bonding technique using resin adhesive and the alternative bonding technique using compomer (containing glass ionomer) adhesive by adding a layer of compomer adhesive at the molar/tube interface.

Enrollment: 30 estimated patients

Sex: All

Ages: 12+ years old

Volunteers: No Healthy Volunteers

Inclusion criteria

1. Patients requiring fixed appliance orthodontic treatment (with no previous orthodontic treatment).

2. Patients aged >12 years with full permanent dentition (excluding third molars).

   • Caries, abrasion, or any other crown defect (like hypoplasia).
   • Pretreatment chemical agents.
   • Restorations or fractures.
   • Morphological modifications or other crown alterations.

4. Patients who have the desire and ability to comply with the trial protocol.

Exclusion criteria

1. Treatments with planned extraction of first permanent molars.
2. Occlusal interference that prevents correct position of molar tube.
3. Patients with a craniofacial anomaly (like cleft lip and palate) and/or require orthognathic surgery.
4. Patients that require extra-oral or intra-oral anchorage device (headgear, palatal arch, lingual arch) or expander (quad-helix, hyrax).
5. Lack of consent to participate in the trial.
