PFM In Dentistry No Any Poisonous Side Effect Pure Titanium Dental Post and Core

 

 

Steps in tooth preparation

Removal of RC filling material

Enlargement of the canal

Preparation of coronal tooth structure

 

Prefabricated post and core system

Eliminate weaker residual walls, clean up the cavity, preserving all healthy dentine 

Prepare the root canal according to your usual procedure (Gates,paesso reamers) the post is chosen according to the canal's diameter, not to the root's.

 

Prepare the composite bonding cement, coat the post Insert it immediately into the canal

Fit the core form boxing system Fill up with the core composite while pressing and polymerize

Custom cast post system

Direct technique

Indirect technique

 

Remove any weak, thin, and/or unsupported tooth structure.

Direct technique

Using progressively larger diameter Pesso reamers remove the gutta percha to the predetermined initial depth

Repeat this process as necessary leaving 4-5 mm of gutta percha as an apical seal. 

 

Add a keyway to resist rotation of the post/core. Place the keyway in the bulkiest part of the remaining tooth structure.

 

Try-in the preformed plastic post and be sure it goes all the way down the prepared canal without binding (a totally passive fit). Trim it as necessary. Measure the post relative to the depth of the canal with a periodontal probe

 

Lubricate the canal with Duralay lubricant

Using the &quot;bead brush&quot; technique, fill the canal completely with Duralay resin. Use the bristles of a brush (bent at a 45 degree angle for easier access) to force acrylic down the canal and express any trapped air

 

Immediately, dip the plastic post in acrylic liquid (to soften post and enhance bond of acrylic) and seat it in the canal to its full depth. </li></ul><ul><li>Move the post up and down in the canal 1-2 mm (only after the Duralay is nearly set) to avoid getting it &quot;locked in.&quot; 

 

Using hemostats, carefully remove the post pattern and inspect it to be sure it is fully formed (with no voids). 

 

Cut off the top of the plastic post so that your patient can close completely 

Using a large diameter coarse diamond (high speed handpiece at &quot;near stall&quot; speed with water spray), shape the pattern to ideal preparation form (on the tooth). 

 

Using hemostats (held mesiodistally), remove the pattern from the tooth. The pattern should not be removed (except one time to check that the post portion is fully formed) until it is completed. There is the risk of breakage each additional time the pattern is removed.
