Obturator (dentistry)

from Wikipedia, the free encyclopedia

In dentistry, an obturator (lat .: obturare clogging, sealing) is understood to mean a device for closing jaw defects that can not be surgically closed temporarily or permanently and, on the other hand, a special locking pin for root canal treatment .

It is seldom used for cleft lip and palate . The obturator can be used alone or as an additional component of a prosthesis to replace teeth , which thereby becomes a defect prosthesis.

Cyst obturator

After an operation on a large cyst in the jaw area, which is usually located in the ascending branch of the lower jaw , an obturator is inserted to prevent the wound from closing too early. The purpose is to give the slowly growing bone tissue time to form new bone and at the same time to seal the cyst cavity from the oral cavity. The plastic lying in the cyst cavity is gradually removed - in accordance with the bone growth - and the obturator is increasingly made smaller.

Root canal obturator

An obturator is used to fill the root canal in order to seal the root canal . Systems such as Soft-Core / One-Step, HEROfill, Densfill and Thermafil are on the market for this purpose. The latter is, for example, an obturator made of special plastic and coated with α-phase gutta-percha .
