Endodontic Posts
Before proceeding refer above for Treatment of the Restoration and Tooth Conditioning/Dentin Pretreatment
a. Place 2-3 drops of One Part Denti/Enamel Bonding Agent adhesive directly into a clean well. Replace cap.
b. Apply One Part Denti/Enamel Bonding Agent adhesive to post preparation with a brush, being sure to apply generous amounts to the preparation orifice. A paper point pre-wetted with the adhesive may aid in bringing the adhesive mixture down to the deepest portion of the preparation. Maintain contact of adhesive with tooth structure for at least 20 seconds.
c. Air dry treated post preparation with air syringe. Use of clean, dry paper points may aid in thorough removal of acetone in post space. Surface should have a uniform glossy appearance. If not, repeat application and air dry. Be sure there is no pooling. Light cure for 20 seconds.
d. Apply a single coat of One Part Denti/Enamel Bonding Agent adhesive to the post with the same brush followed by gentle air drying for 5 seconds. Light cure for 20 seconds.
Cementation Technique
a. Dispense the desired shade of Resin Cement base paste from the syringe onto a clean mixing pad. A light base shade e.g., Light Universal will allow maximum light transmission. Dispense an equal amount of catalyst paste. Mix the cement for 10-20 seconds.
As with any dual cure resin cement system, the working time is shortened.
b. Spread mixed Resin Cement components on surface of post and/or into the post preparation with a syringe tip, Lentulo Spiral or metal file.
c. Seat post immediately. Clean up excess with appropriate instruments. A 10 second light exposure "pre-cure" of excess cement at the margins will cause cement to "gel", allowing easy cleanup.
d. Stabilize post until cement sets. Apply moderate and consistent pressure to the restoration throughout the self-cure set time of approximately 6 minutes from the beginning of mixing. Light cure the cemented post for 20 seconds.
Proceed with core build-up and/or preparation.
FinIshing and Polishing
Removal of resin flash is best accomplished with a finishing system including points, cups and discs.
Polish final restoration using Polishing Paste and a wet polishing system.
