Behind the Smile: Managing Class I Malocclusion and Protrusive Upper Incisors With Kalra Simultaneous Intrusion and...

Malocclusion is defined as any deviation from the ideal occlusal positions and the position of the specific teeth. Those that are common are numerous and affect a patient's stomatology and dental structures in appearance and utility. Class I is the most common type and favors the anterior relationship of both jaws, which lies between the second and third quartiles. Its cause is still unknown at the moment. It is even more frequent than usual occlusion. Class I malocclusion with an overjet of upper incisors less than 4 mm accompanied by type 2 of Dewey's modification also displays protruded upper incisors and a deep overbite. This case report's focus is to provide an extensive evaluation of the diagnostic process, management plan, and outcome for a patient who had presented with this specific dental abnormality and simultaneous intrusion and retraction mechanics for an anterior segment with Kalra Simultaneous Intrusion and Retraction (K-SIR) loops.
