that part of the alveolar process that lines the bony sockets into which the roots of the teeth are embedded
alveolar crest
the highest point of the alveolar process

alveolar process
the extension of the maxilla and mandible that surrounds and supports the teeth to form the dental arches; alveolar ridge

waste, regulated
liquid or semiliquid blood or other potentially infectious materials; items that would release blood or other potentially infectious materials if compressed
