Evaluation of The Stability of Orthodontic Treatment After First Premolar Extraction Using Combined Retention Protocol

Egypt24 participantsStarted 2024-03-10

Plain-language summary

The aim of this study is to compare between the stability of anterior and posterior segments in both arches using bonded lingual retainers versus a combined protocol of retention (bonded lingual retainer and vacuum formed retainers). The effect of different treatment changes achieved on the post-treatment stability will be studied in both groups. Hypothesis: No difference between BR and BR+VFR regarding the stability of anterior segment alignment and posterior segment alignment and interdigitation
