Abstract
Introduction: Simultaneous intrusion and retraction results in correction of proclination of incisors, reduction in overjet and overbite with closure of space. This can be achieved by K-SIR arch.
Aims and Objectives: To evaluate the skeletal, dental, soft tissue changes and amount of anchor loss during simultaneous intrusion and retraction with K-SIR arch.
Materials and Methods: Total 20 subjects were selected from the patients visiting department of orthodontics. Simultaneous intrusion and retraction was carried out using K-SIR arch. Two lateral cephalograms were taken one, at the beginning of the treatment (T1) and other at the completion of the retraction and intrusion (T2).
Results: There was significant amount of intrusion and retraction was seen.
Conclusion: The K-SIR arch showed significant amount of retraction and intrusion of upper incisors and showed some amount of extrusion of molars, change in FMA and anchor loss.
Keywords: K-SIR arch, retraction, intrusion
