Abstract
Labially positioned mandibular incisors with traumatic occlusion easily cause localized gingival recession and hypermobility, because they tend to have thin alveolar bone in the labial.
In two cases of anterior crossbite with the labially positioned mandibular incisors at an early stage, we improved the crossbite with orthodontic treatment.
The result was that the localized gingival recession recovered and the hypermobility of the teeth disappeared.
We reported on the clinical signs and the process of the treatment of these two cases. We also investigated the relation between the improvement in the anterior crossbite at an early stage and the recovery and maintenance of the periodontal health.
It is thought that orthodontic treatment and professional plaque control at an early stage appeared to be the most important factors in the treatment of localized gingival recession and hypermobility of the mandibular incisors with anterior crossbite.
The "development" was a characteristic of children, and was necessary for the recovery of gingival recession. Orthodontic treatment at an early stage made the best of the "development".
Toward this treatment at an early stage contributed maintaining the normality of the occlusion and the periodontal health all through the life cycle.
