Abstract
The accuracy of brackets placement is a key factor in successful orthodontic therapy. An in vitro study was conducted in ten models from a natural maxillary teeth model in order to compare the accuracy of brac- kets placement between two direct bonding instru- ments: the Pole-like Bracket Positioning Gauge and the Star-like Bracket Positioning Gauge. Our results have shown that: The Star-like Bracket Positioning Gauge is more precise in placing brackets vertically, whereas the Pole-like Bracket Positioning Gauge al-lows a better angulation of the bracket. Considering each tooth separately, there is no statistically signifi-cant difference between the two positioning gauges, except that the Star-like gauge gives better results in bracket’s height for the second premolar and the ca-nine, whereas the Pole-like gauge allows for a better positioning and a better vertical angulation of the brackets for the lateral incisor. No statistically signi- ficant difference was found between the two gauges on the mesiodistal position. Overall, the Star-like gau- ge showed a better accuracy in positioning brackets.

Mesiodistal positioning: The comparison between the group of teeth bonded with the star-like gauge and the pole-like gauge shows a significant difference for the first premolar and the lateral incisor (Table 4)
Summary
Good placement of orthodontic brackets guarantees a successful mechanical treatment [1]. Direct bonding is the technique that is most used by orthodontists in their daily practice [2]. Two positioning instruments are available to the practitioner, the pole like gauge and the star like gauge known as Boone gauge. The question that arises is which of these two instruments is more accurate in terms of positioning orthodontic brackets. There are no studies comparing the pole like gauge and the star like gauge in bonding brackets. Our work has taken as objective to compare the accuracy of orthodontic bracket placement between two instruments of direct bonding: the star like and the pole like gauges
