Ortodontide Alerji: Güncel Bulgular, Risk Faktörleri ve Klinik Yönetim
Synopsis
The choice between 0.018-inch and 0.022-inch slot conventional bracket systems has been debated for decades. Laboratory studies have demonstrated that the 0.018-inch slot provides earlier full torque expression. However, whether this biomechanical difference translates into clinical outcomes remained unclear until recently. This review integrates the biomechanical rationale regarding slot dimension, manufacturing tolerances in commercial brackets, and current clinical evidence. Manufacturing variability, active ligation with stainless steel ligatures, and the adaptive response of the periodontal ligament explain why differences measured in the laboratory do not manifest clinically. Current evidence indicates that bracket slot size selection can be based on practical considerations such as archwire inventory and clinical workflow rather than a presumed biomechanical superiority.
