Background
Well-finished orthodontic treatment begins with accurate positioning of the brackets on the teeth.
Aims
To compare the positions of orthodontic brackets placed by experienced clinicians and inexperienced trainees.
Methods
Twenty orthodontists (13 male, 7 female) representing experienced specialists, and 20 final year dental students (10 male, 10 female) representing inexperienced trainees, were asked to bond pre-adjusted straight-wire brackets at the centres of the clinical crowns of the teeth in a Class I crowded typodont set-up. The teeth were removed from the typodont, placed in a standardised jig and photographed. The vertical, mesio-distal and angular (tip) positions of the brackets, relative to the centres of the clinical crowns, were measured with the aid of imaging software. The accuracy of bracket placement by the groups was compared.
Results
The dental students took significantly longer than orthodontists to place the brackets (50.65 ± 16.33 minutes vs 28.53 ± 9.51 minutes,
Conclusions
Accurate direct bonding of orthodontic brackets to teeth does not appear to be related to clinical experience or specialist training.
