Perforated like a sieve, for example, the cribriform plate of the ethmoid sinus. Having small holes like a sieve.  

The fluid that is typically produced in the presence of inflammation and seeps through the crevicular epithelium; it can serve as a defense mechanism against infection by carrying antibodies and other substances into the sulcus. Also known as sulcular fluid and gingival fluid.

The layer of compact bone at the alveolar crest.  

An incision made at the crest of the edentulous ridge.  

The placement of a dental implant with the edge of its platform at the crest of bone. a) Subcrestal implant placement: the placement of a dental implant with the edge of its platform apical to the crest of bone. b) Supracrestal implant placement: the placement of a dental implant with the edge of its platform…

Bone resorption of the most coronal aspect of the ridge around the neck of the implant.  

Pertaining to the crest or the most coronal portion of the ridge.  

The highest continuous surface of the residual ridge, not necessarily coincident with the center of the ridge.
