Orthodontic and surgical intervention to arrest tooth loss secondary to subgingival elastic.

Elastic bonds used for orthodontic tooth movement without benefit of attached mechanisms have been shown to migrate apically, causing severe periodontal damage and eventual tooth mobility and tooth loss. The literature indicates high mortality rates for such involved teeth. A case report is presented, illustrating initial successful retention of teeth following surgical removal of a displaced elastic band. Cooperation between oral surgeon, periodontist, and orthodontist, in conjunction with high standards of oral hygiene by the patient, may lead to successful retention of otherwise condemned teeth. It is also suggested that elastic band therapy be carefully supervised when used to move teeth without controlling attachment mechanisms.
