NCT04670211

Brief Summary

The investigators will perform a prospective, non-randomized observational study. The aim of this study is to evaluate stability of tooth-borne, bone-borne and hybrid expansion following SARPE by using data collected according to the existing SARPE follow-up protocol. The insights of this study might elucidate the preferred expansion technique and improve surgical technique.

Outcome Measures

Primary Outcomes (1)

  • Stability

    Stability of the maxillary expansion following SARPE. The stability will be evaluated by comparing the CBCT imaging which is taken at the time of maximal transversal maxillary expansion with the CBCT taken one year postoperatively. Width between the mesiobuccal cusps of the first molars and width between the cusps of the canines is measured. Moreover the width of the apertura piriformis and between the palatal foramen is examined in order to evaluate skeletal stability. This allows calculation of the dental and skeletal stability following SARPE.

Secondary Outcomes (1)

  • Complications

    1 year postoperatively
