What is the proper orthodontic approach for a defect with flat bone level and uneven marginal ridges?

The proper orthodontic approach in the case of a defect characterized by a flat bone level and uneven marginal ridges is to equilibrate the crown and consider endodontic treatment. This approach is advantageous because it focuses on achieving a balance between the restorative needs and the underlying structural integrity of the teeth in question.

Equilibrating the crown can address the uneven marginal ridges by adjusting the occlusion, thereby enhancing the functional and aesthetic aspect of the teeth. If a tooth exhibits significant wear or structural compromise that may lead to further issues such as pulp necrosis, considering endodontic treatment may prevent future complications and prolong the tooth's viability.

This method acknowledges the importance of maintaining the teeth rather than opting for more invasive measures, such as extracting the involved teeth or performing bone grafts, which may not be necessary and could have more complicated implications for the patient's oral health and treatment plan. Leveling the marginal ridges with the bone is generally not viable in this context, as it does not directly address the primary concerns regarding the structural health of the teeth involved.

In this case, focusing on the crowns and restoring proper alignment and function while monitoring the overall dental health is the preferred orthodontic approach.
