Evaluation of Stress Distribution and Displacement in the Affected Periodontium of Mandibular Incisors Using Utility Intrusion and Reverse Curve of Spee Arch Wires: A Finite Element Analysis

Elevated bone loss in mandibular incisors resulted in increased stress distribution and decreased displacement, implying a tendency toward labial tipping. The utility intrusion arch wire consistently exhibited higher stress distribution but minimized displacement compared to the RCS arch wire, highlighting its potential for better torque control and reduced labial tipping, particularly with the progression of horizontal bone loss.
