Clinical Insights Into Lower Incisor Extraction for Orthodontic Treatment: A Case Report

Extracting a single lower front tooth can be an appropriate treatment for class I malocclusions when the alignment of the upper teeth is normal and there is an adequate overlap of the teeth. This approach is particularly effective in cases of significant crowding in the lower front teeth, especially when the space deficiency exceeds 4-5 mm and the combined width of the lower front teeth surpasses 83 mm. It is also a viable option for malocclusions resulting from discrepancies in tooth size, such as narrower upper front teeth or larger lower front teeth. Research suggests that this method leads to better post-treatment stability compared to the conventional approach of premolar extraction. The success of this treatment is contingent upon meticulous diagnosis, comprehensive planning, and the expertise of the orthodontic professional. This method not only addresses specific issues of space and alignment but also provides a more stable and predictable long-term outcome for patients with these particular orthodontic challenges.
