Abstract
Bracket positioning is a fundamental aspect of orthodontics, resulting in force delivery in three planes of space using the straight wire appliance. Ideal bracket placement aims to achieve esthetic and functional tooth position, with a consonant smile arc, as well as level marginal ridges and interdigitated buccal segments. Variation in bracket positioning alters the expression of the prescription of the straight wire appliance, and consequently tooth position in three planes of space. A variety of approaches have been proposed for ideal bracket positioning, however, shortcomings are evident and detailed in this paper, which reviews the different positioning methods and identifies their shortcomings. Described is a new method of bracket positioning, Smile Arc and Marginal Ridge Approach (SAMRA), designed to achieve the goals of bracket positioning consistently and reliably.
