Summary

Bimaxillary dental proclination is the condition where the upper and lower dental arches are procline thus increase lip fullness. Since the aim of orthodontic treatment in bimaxillary proclination in to get flatten profile where the incisor inclinations are purposely reduced or interincisal angle are increased, therefore it is guarded for corrected dentition to maintain stable or not post orthodontic treatment.Therefore, this study is looking into evidence which is the best retainer to maintain stability of bimaxillary proclination cases following fixed appliances treatment.

Conditions

  • Bimaxillary Proclination

Interventions

OTHER

Vacuum formed retainer, fixed bonded retainer, vacuum formed and fixed bonded retainer

Patients will be instructed to wear the removable vacuum form retainer for 8 to 10 hours per day and only removed the retainers during tooth brushing. (Thickett 2010), (Gill 2007). The vacuum formed retainer will be constructed using thermoplastic material that will be purchased from manufacturer at 1.0mm thickness. Meanwhile, bonded retainer will be done using Ormco ® response deadsoft retainer wire size 0.190 round, made in USA by ORMCO Corporation, the fixed bonded wire will be extended distal to the extraction spaces that were previously closed by fixed appliances on both the upper and lower arches. The bonded retainer will be wearing by patients for 24 hours. Double regime retainer that will be comprised of vacuum formed and bonded retainer will be constructed using the same properties as vacuum formed retainer and bonded retainer. A standard oral and written instruction will be given to patients regarding retainer's uses. (Shawesh M et.al, 2009).
