The hollow region at the front of the guard is termed the " alveolus ", and this houses a chambered conical-shaped part of the shell ( called the " phragmocone " ).

In the case of a labial-oral-nasal fistula, the plate may include an anterior upward extension to fully occlude the passageway running between the labial surface of the alveolus, alveolus, and nasal cavity.

Benson " et al . " ( 2013 ) diagnosed the species based on three autapomorphies . " P . westburyensis " has widely spaced premaxillary alveoli, with interalveolar walls approximately half the anteroposterior length of a single alveolus.

The alveolus of MACN Pv-RN 975 fits the lower incisors attributed to " Ferugliotherium " in size and the blade-like premolar is of the size expected for an animal with molariforms the size of " Ferugliotherium " teeth.
36.
"W . ridei " is known from a right maxillary fragment ( QMF 16851 ) containing molars one and two to the anterior section of the infraorbital foramen that was dorsal to the third alveolus intact, mo material remains after molar three.
37.
The gas pressure ( " P " ) needed to keep equilibrium between the collapsing force of surface tension ( " ? " ) and the expanding force of gas in an alveolus of radius " r " is expressed by the law of Laplace:
38.
The following is an example of one such clinical competency ( excision of a buried tooth root ) : If a clinician is deemed to be clinically competent in the surgical removal of a buried root, this implies much more than the technical and surgical ability required to excise a buried piece of root from alveolus.

The small part in front of this suture constitutes the premaxilla ( " os incisivum " ), which in most vertebrates forms an independent bone; it includes the whole thickness of the alveolus, the corresponding part of the floor of the nose and the anterior nasal spine, and contains the sockets of the incisor teeth.
