Which scenario describes the best approach for dealing with non-ankylosed missing L5's?

Maintaining and using interproximal reduction (IPR) represents the best approach for dealing with non-ankylosed missing L5's because it allows for the preservation of the surrounding dental and periodontal structures while minimizing the need for more invasive procedures. In cases of missing teeth, such as the L5, preserving the existing dentition is crucial for maintaining occlusion and facilitating proper function.

Using IPR provides a way to create sufficient space to achieve ideal interarch relationships without resorting to extraction or implants. This method can help to contour the adjacent teeth, improving esthetics and function while often being less traumatic for the patient. Furthermore, IPR can aid in maintaining the health of the periodontal tissue by reducing the risk of overcrowding or misalignment caused by the shift of teeth into the empty space.

In contrast, extracting and replacing with implants requires surgical intervention and may involve greater patient discomfort and a longer treatment timeline. This approach may not always be necessary if IPR can achieve the desired results with less complexity. Closing the space completely through extraction without having a comprehensive plan can lead to alignment and occlusion issues. Waiting for natural eruption may not be feasible or effective, especially if the missing L5 has implications for the overall dental health and alignment of
