What is one repercussion of lower incisor positioning?

Positioning of the lower incisors has significant implications for periodontal health. When incisors are incorrectly positioned, it can affect the way forces are distributed during biting and chewing. This can lead to localized areas of increased stress on the periodontal tissues, potentially causing gum recession or periodontal disease over time. Proper alignment of the lower incisors helps to ensure that occlusal forces are more evenly distributed across the teeth, thereby promoting better periodontal health.

In contrast, improved aesthetics, functional enhancement, and reduced treatment time are not direct repercussions of incisor positioning. While better positioning can contribute to improved aesthetics or functional outcomes in the long run, these are secondary effects rather than immediate repercussions. Similarly, treatment time may vary based on many factors, including the complexity of the case and the treatment plan, rather than solely on the positioning of the lower incisors. Thus, while they may be positive aspects of orthodontic treatment, they do not capture the major concern associated with the positioning of lower incisors as it relates to periodontal health.
