Abstract :
Background and Objective: The simplicity of placing Temporary Anchorage Devices (TADs) has made them popular for controlling anchorage and treating vertical maxillary excess. This study aimed to compare the effects of stainless-steel ligature wire and elastic chain on maxillary incisor intrusion and root resorption in patients with Angle’s Class I maxillary dentoalveolar protrusion requiring simultaneous retraction and intrusion.Materials and Methods: Twenty-two patients were divided into two groups of eleven. Group 1 was treated with midline mini-implants and intrusive force via ligature wire. Group 2 received the mini-implants and intrusive force applied via elastic chain. Lateral cephalograms and Radiovisiographs were taken at the start (T1) and after space closure (T2) to evaluate intrusion and root resorption.Results: Group 1, utilizing midline mini-implants with ligature tie, demonstrated an average intrusion of approximately 2.66±1.67 mm and 2.72±1.48mm with respect to SN plane and Palatal plane PP respectively. Meanwhile, Group 2, employing midline mini-implants with elastic chain, exhibited an average intrusion of 3±1.32mm and 3.06±1.22mm with respect to SN plane and PP respectively. Amount of root resorption was 0.40±0.19 mm in Group 1 and 0.82±0.77 mm in Group 2, and was found to be statistically significant (P
