This study examined factors affecting bracket detachment in 197 orthodontic patients (116 females, 81 males; mean age 16.3 years) treated with stainless steel non-self-ligating brackets over an average of 23.7 months. Bracket failure was recorded as the main outcome. Variables included patient demographics, oral hygiene, treatment duration, and cephalometric measures such as overjet, overbite, and skeletal relationships. Overall, 4.4% of brackets failed, with higher rates on posterior teeth and the right side. Male patients, poor oral hygiene, and increased overjet or overbite were associated with greater risk.
