Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

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

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Retention is necessary to be done after orthodontic treatment. It aids to prevent the tendency for relapse of teeth toward their pretreatment position. Fixed or removable retention appliances can reduce the risk of relapse, but to date there is still limited evidence on treatment protocols, wearing time and duration. However, long-term retention with bonded lingual retainers is commonly recommended and often considered the gold standard (method of first choice) in orthodontic retention. Regardless of the expected benefits concerning tooth stabilization, aesthetic appearance and independency from the patient's compliance, there have been increasing numbers of reports on undesirable changes in tooth position in the presence of retainers. Since "active" lingual retainers are able to exert forces to teeth, they have been suspected of causing torque changes of adjacent incisors ("X-effect"). Therefore, several authors recommend to insert removable and fixed in both arches for maximum relapse prevention.
