Oral synechia

What it means

Fibrous band between the mucosal surfaces of the upper and lower alveolar ridges.

These bands must be distinguished from synechiaee between the tongue and palate (glossopalatal ankylosis) and from synechiae arising from the floor of the mouth (as in the subglossopalatal membrane), oropharyngeal isthmus (as in persistent buccopharyngeal membrane) or from the lower lip. If there is a complete soft tissue contiguity between the upper and lower alveolar ridges, the term, Fibrous syngnathia should be used instead.
