Treatment
The essential requirement for using this post and core is its bur, which is manufactured in different sizes to produce an additional circle ring around the canal of a tooth.
The same as traditional treatment method by any post and core, the root canal is prepared using parallel-side twist drill after treating and filling canal by an inert gutta percha or similar material. Then root canal needs to be prepared with the maximum possible depth for the second stage. However, it has to be noticed that the minimum essential requirement of canal is one third of its length, which is necessary in roder to fix the core.
In the next stage, using the specific bur, dentist prepares an additional circle ring around the tooth canal. The post and core can then be constructed either by a direct technique or by an indirect technique. In the direct technique a pattern is fabricated in the mouth using either inlay wax or a burn out resin (e.g. Duralay) which is then sent to the laboratory for casting. For the direct technique, which is more widely used, an impression is taken using a matched plastic impression post placed in the prepared post hole.
For the post-core, it is possible to use different material such as metals or the high strong fibres which is used in dental laboratories.

Famous quotes containing the word treatment:
“To me, nothing can be more important than giving children books, It’s better to be giving books to children than drug treatment to them when they’re 15 years old. Did it ever occur to anyone that if you put nice libraries in public schools you wouldn’t have to put them in prisons?”
—Fran Lebowitz (20th century)
“James’s great gift, of course, was his ability to tell a plot in shimmering detail with such delicacy of treatment and such fine aloofness—that is, reluctance to engage in any direct grappling with what, in the play or story, had actually “taken place”Mthat his listeners often did not, in the end, know what had, to put it in another way, “gone on.””
—James Thurber (1894–1961)
“I am glad you agree with me as to the treatment of the mining riots. We shall crush out the lawbreakers if the courts and juries do not fail.”
—Rutherford Birchard Hayes (1822–1893)
