Comparison Between Two Rates of Activation of Miniscrew-Supported Upper Jaw Expander in Adolescents

Egypt30 participantsStarted 2019-03-01

Plain-language summary

Miniscrew-supported maxillary expanders provide advantages over conventional tooth-supported expanders. However, there is no consensus in the literature regarding their activation protocol. The purpose of the clinical trial is to evaluate and compare the effects of slow and rapid activation rates of miniscrew-supported expanders on the skeletal changes, dento-alveolar changes and the pain experience.

Inclusion Criteria: * Permanent dentition. * Participants indicated for skeletal maxillary expansion due to unilateral or bilateral posterior cross bite or maxillary transverse deficiency * Good oral hygiene Exclusion Criteria: * History of previous orthodontic or orthopedic treatment * History of maxillary trauma * Patients with congenital craniofacial malformations * Patients receiving pharmacological agents or having systemic diseases that might affect the bone metabolism or the pain response

What they're measuring

Transverse skeletal changes from baseline to an average of 5 months after the initial activation, measured using cone beam computed tomography (CBCT)

Timeframe: At baseline and an average of 5 months after the initial activation

Dento-alveolar inclination changes from baseline to an average of 5 months after the initial activation, measured using CBCT

Timeframe: At baseline and an average of 5 months after the initial activation
