Filter by:Bimaxillary protrusion are common in Malaysia due to the prevalence in the two biggest races (Malay and Chinese). However, evidence for treatment methods and outcomes for bimaxillary protrusion patients are scarce. The need for high anchorage in bimaxillary protrusion cases also makes them perfect candidates for a study on the effectiveness of different anchorage methods commonly used in treatment of bimaxillary protrusion cases. The soft tissue outcomes from the use of these different methods are also our area of interest. Hence, the investigators aim is to prove that molar block anchorage similarly effective and has the same outcome as using other conventional auxiliary anchorage such as TPA and Nance button in treating patients with bimaxillary protrusion.
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.
The study is a single blind randomised control trial.The patients will be randomly assigned to have conventional brackets placed or self ligating brackets placed. All patients will undergo full Orthodontic records. This will include an Orthodontic assesment, study models relevant xrays (orthopantogram and a cephalomgram) and clinical photos. After records analysis, patients will be given a prophylaxis and oral hygiene instructions. Either 3m Victory Series™ Metal Braces or 3m SmartClip™ SL3 Self-Ligating Braces both bracket types will carry the MBT prescription 0.022 slot height, will be bonded using Transbond™ XT (3M Unitek, Monrovia, California, USA) composite resin according to the manufactuer's instruction. These patients will be recalled at monthly intervals for the duration of treatment time which will be 3 years. A cephalogram will be taken at the end of treatment
This study evaluates the profile changes and torque control using lingual lever arm vs conventional lingual mechanics. Half of the patients will receive lever arms and the other half will receive conventional lingual orthodontics.
