Management of the dento-periodontomuscular imbalances in the incisor–canine mandibular region by labiomental weakening surgery and corticotomy

Incisor and canine mandibular regions are a key mechanical vault, which strives with strong muscle and occlusal centripetal forces. In cases of dental and / or periodontal weakness and / or excessive mechanical stress, situations of imbalance can affect the stability of orthodontic treatments and periodontal durability.This article reports two surgical techniques to prevent and treat these situations: The labiomental weakening in growing children and adolescents; Alveolar corticotomy with vestibular allograft bone in adults;Both techniques allow functional management of mechanical imbalance, improvement of the periodontal biotype, and promote lower incisors’ relocation.
