Eligibility Criteria

Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.

Inclusion Criteria

* For group 1(Hybrid hyrax distalizer) Patients suffering maxillary collapse with a skeletal background with unilateral or bilateral posterior crossbite.
* For group 2 (Pendulum distalizer) Patients with skeletal class I or class II malocclusion who needed upper first and second molar distalization for incisor retraction or relieving of the upper arch crowding and minimum or no crowding in lower jaw were selected.
* All Patients had no systemic diseases that may affect bone quality or interfere with orthodontic treatment, periodontal disease and no previous orthodontic treatment.
* Age range was 13 to 17 years.
