Long-term follow-up of a patient with deepbite and severely resorbed maxillary central incisors treated by maxillary premolar and mandibular incisor extraction.

Deepbite is a common type of malocclusion, but it leads to difficulties in treatment and retention. We report the treatment of an adult patient with deepbite and severe crowding of teeth. Several teeth had to be restored, and the maxillary central incisors had short roots.

Risk factors associated with open gingival embrasures after orthodontic treatment.

Objectives: To investigate the incidence of and contributing factors to open gingival embrasures between the central incisors after orthodontic treatment.

Materials And Methods: One hundred posttreatment patients (29 men and 71 women; mean age, 24.7 years) were divided retrospectively into occurrence and nonoccurrence groups based on intraoral photographs.
