Evaluation of Bracket Positioning; A Customized System Versus the Conventional Method

KSKübra SucuUniversity of Health Science MÖMete ÖzerIstanbul Metropolitan Municipality

Key Result

The Insignia system and Kalange's method position anterior brackets more incisally compared to posterior brackets relative to Andrews' FA point.

Key Points

This research evaluates how brackets are positioned in a customized vs. a conventional system.
Compared bracket positioning in the Insignia system and Kalange's method.
Measured the positioning relative to Andrews' FA point.
Analyzed the placement differences between anterior and posterior brackets.
Brackets in both methods were placed more incisally/occlusally than Andrews' FA point.
Anterior brackets are positioned more incisally than posterior brackets in both systems.

Structured PICO

Does the Insignia system or modified Kalange method result in different vertical bracket positioning compared to Andrews' FA point in patients undergoing fixed orthodontic treatment?

Population

26 patients with permanent dentition from first molar to first molar and Little's Irregularity Index ≤3 mm (minimal crowding), mean age 15.38, 73.1% female.

Intervention

Insignia Advantage system (custom self-ligating brackets, Damon Q) with digital treatment planning and indirect bonding

Comparator

Modified Kalange method (virtual brackets, Damon Q) with digital placement and indirect bonding

Outcome

Deviation of bracket position from the ideal position (Andrews' FA point) along the vertical axissurrogate

Both the Insignia system and the modified Kalange method position orthodontic brackets more incisally/occlusally compared to the conventional Andrews' FA point, particularly in the anterior region.

Main Result

Absolute Event Rate: 0% vs 0%

Abstract

In the Insignia system and Kalange's method, brackets are positioned more incisally/occlusally relative to Andrews' FA point. In both methods, anterior brackets are positioned more incisally than posterior brackets.
