As bone looses width, height, volume, the attached gingiva gradually decreases and is prone to abrasions caused by the overlying prosthesis. In addition high muscle attachments and hypermobile tissue often complicates the situation. The tongue of the patient with edentulous ridges often enlarges to accommodate the increase in space formerly occupied by the teeth. As a result the stability of removable prosthesis is jeopardised or further decreases.
