During orthodontic treatment, some patients need to undergo significant labiolingual movement of the anterior teeth. Patients with pre-existing alveolar bone defects in the anterior teeth, due to the thin morphology of the soft and hard tissues around these teeth, are prone to exacerbating the original bone defects (bone fenestration, bone dehiscence) during the orthodontic process. Commonly, issu
