Abstract

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.
