OBJECTIVE: Some of the most significant aspects in orthodontics for achieving favorable treatment outcomes include correct bracket positioning and a shorter period to accomplish bracket bonding. Two different brackets bonding techniques – direct and indirect bonding – are described in the literature. The aim of this review is to evaluate the differences, advantages, and disadvantages of the two techniques.

MATERIALS AND METHODS: A literature search was conducted on PubMed, Scopus, and Web of Science databases in a period from January 2013 to April 2023 with English language restriction using the following Boolean keywords: “orthodontic bracket* AND (bonding OR placement)”.

RESULTS: A total of 3,820 articles were identified by the electronic search, and after duplicate removal, screening, and eligibility, a total of 11 papers were included for the qualitative analysis.

CONCLUSIONS: Indirect bonding is more predictable and precise than direct bonding. Indirect bonding has a greater impact on minimizing bracket placement errors than direct bonding, but it still takes longer to complete than the traditional procedure. However, further studies on the differences between direct and indirect bonding, as well as digital bonding, are needed.
