obturation

The cartridge case also provides obturation, or sealing the chamber.

Typically for a quick-firing gun, the cartridge case provided obturation.

When a cartridge is fired, the internal pressure expands the case to fit the chamber in a process called obturation.

The gun fires separate ammunition using a metal cartridge case that also provides obturation.

Also revealed problems with the obturation at a shot, which in the classical configuration cartridge provides sleeve.

The breech would fail to close entirely after several shots due to the lack of an effective obturation seal.

This would affect the ballistics of the weapon if a means of obturation were not introduced.

With bagged charges the breech itself provides obturation and holds the primer.

Like most Soviet artillery the gun fires separate ammunition using metal cartridge cases that also provide obturation.

This procedure helps prepare root canals for obturation.

(1) In weapons using semifixed ammunition, obturation is accomplished by means of the cartridge case.

This required the obturation to be provided by the breech rather than the cartridge case, as is the case in fixed rounds.

Hence, unlike with a metal rifle cartridge, the breech mechanism itself somehow needed to provide obturation.

One such characteristic is the type of obturation used to seal the chamber and prevent gases escaping through the breech.

Exposure of the obturation material to the oral environment may mean the gutta-percha is contaminated with oral bacteria.

The palatal obturation may be managed temporarily or may be sustained for longer periods of time.

This prevented propellant gases from blowing around the projectile providing obturation as the driving band had yet to be perfected.

The 3D scrubbing effect of the file, combined with the fresh irrigant, result in clean canals, which in turn facilitate better obturation.

Note: all ammunition currently manufactured by Wolf has polymer-coated or brass cartridge cases and any obturation problems have been radically reduced.

A degree of obturation was achieved via a cup on the face of the block being forced into a recessed ring on the chamber face.

In the field of firearms and airguns, obturation denotes necessary barrel blockage or fitment by a deformed soft projectile.

To allow obturation in airguns, pellets use soft alloys in conjunction with a thin, concave base designed to expand more easily.

Speech therapy may be most beneficial prior to sustained palatal obturation rather than short-term obturation.

Canal preparation and obturation using lateral condensation, gutta-percha, and AH 26 sealer was performed on all of the teeth.
