The endalveolar crest: anatomic and prosthodontic considerations of an overlooked mandibular landmark

Surgical and prosthodontic treatment of edentulous patients have confirmed the presence of a seldom-described crest of bone situated above and distal to the mylohyoid ridge of the mandible. This study aimed to establish the frequency of occurrence and range of expression of the feature, which it is suggested should be called the endalveolar crest in humans and other primates. Evidence of the crest was noted in all specimens examined although the expression varied. Dissection of fresh and preserved cadavers indicated that the crest provided attachment for part of the superior constrictor muscle and that it may also afford some protection to the lingual nerve in the retromolar region.
