Filter by:The use of corticotomy surgery in addition to orthodontic standard treatment could accelerate the treatment. Corticotomy involves vertical interdental incisions of the gingiva and the bone with a very low thickness. Orthodontic appliances are placed immediately after the surgery. This study aims to compare the tooth movement when correcting mandibular dental crowding in two groups of patients: Test group: orthodontic treatment and minimally invasive corticotomy surgery. Control group: standard orthodontic treatment without surgery.
Fixed orthodontic braces are routinely used to straighten teeth and correct the bite of individuals. Once the braces are fit, the patient is recalled every few weeks to adjust or tighten the brace. Although convention states that the patient returns every 6-8 weeks to have the brace adjusted, there is no consensus or evidence to support a specific timeframe. Indeed some orthodontist see their patients as frequently as every 4 weeks and others as long as every 10 weeks. The aim of this investigation is to determine whether the amount of time between brace adjustment appointments has an effect on the overall treatment time. Knowing which appointment interval will lead to the shortest overall treatment time will be of benefit to patients as prolonged orthodontic treatment may be associated with an increased incidence of adverse effects associated with orthodontic treatment. Patients who are to be treated with fixed orthodontic braces at will be invited to take part in the study. Consenting subjects will be randomly allocated into one of four groups. The first will be seen to adjust their brace every 4 weeks, the second group every 6 weeks, the third group every 8 weeks and the fourth group every 10 weeks. The primary outcome measure is the total treatment time. The mean treatment time of each of the four groups will be compared to establish whether or not treatment appointment intervals affects treatment time. Secondary outcome measures will include difference in number of appointments required throughout the course of treatment between groups, differences in treatment outcomes, differences in patient compliance.
In orthodontics, conventional fixed appliances, usually consisting of prefabricated components, require step-by-step adjustment in order to move teeth in the planned direction. May treatment be improved with customized archwires? Study hypotheses: - By using CAD/CAM in planning and fabrication of customized archwires, unnecessary tooth movements can be avoided and teeth can be moved on their direct path to the intended position. - The application of CAD/CAM improves reproducibility, efficiency, and quality of orthodontic treatment.
