Condition(s) studied

Investigational drug(s) / intervention(s)

Rapid palatal expansion

Rapid palatal expansion: Patients undergone orthopedic treatment with rapid palatal expander

Study summary

Recruitment of patients treated using rapid maxillary expanders with dental anchorage, with pre-treatment panoramic X-rays and post-treatment models. In the initial phase of the study, the objective is to correlate the radiographic inclination of the upper permanent premolars in the pre-treatment orthopantomography to the expansion obtained at the end of therapy using a palatal expander with dental anchorage.

Inclusion Criteria: * Patients scheduled for orthopedic treatment with rapid palatal expander * Pre-treatment orthopantomography * Pre and post treatment intraoral scan Exclusion Criteria: * Previous maxillofacial surgery * cleft lip and palate * premolar agenesis or extraction for fracture ecc. * Previous orthopedic-orthodontic treatments

Primary outcome measure(s)

  • Number of required activation for maxillary expansion — T0 (pre-treatment casts/x-rays) and T1 (post-treatment casts/x-rays)
    Correlation between the number of activations of the rapid palatal expander and premolar inclination (angle between the long axis of the premolars with the occlusal plane)
