[How I treat… An open bite secondary to ankylosis of a primary molar tooth].

Infraclusion is a consequence of dentoalveolar ankylosis. Associated complications include extrusion of the opposing tooth, open bites, and tilts. Early detection and management are crucial to limit and/or correct these complications. Different therapeutic options exist when a deciduous tooth is ankylosed : preservation or extraction (with or without space closure). The goal of this article is to highlight the advantages of the injected composite technique for restoring the tooth when preservation has been chosen.
