ALL-CERAMIC/PORCELAIN RESTORATION CEMENTATION.
- Tooth Preparation:
- Remove temporary restoration and clean prepared tooth and try in final restoration for optimum fit. If eugenol containing temporary cement has been used clean the preparation with pumice to remove all traces of cement. Eugenol will affect curing of many composite materials.
- Etch prepared tooth per manufacturer’s instructions.
- Apply contemporary adhesive per manufacturer’s instructions.
- Preparation of All-Ceramic/Porcelain Restoration: (Contact laboratory for proper internal surface treatment i.e., etching. Different ceramics require different surface treatments.
- If the restoration requires silane, apply 1-2 thin coats to the internal surface prior to try-in of the restoration. Wait for 30 seconds. Dry with air syringe.
- Apply silane coupling agent to the internal surface for 30 seconds and Dry with air syringe.
- Apply one coat of contemporary light-cured adhesive and air dry. Light-cure for 10 seconds. OR Apply a thin layer of a light–cured bonding resin. Air thin. DO NOT LIGHT-CURE
- Cementation of Restoration
IMPORTANT. PLEASE READ PRIOR TO USE.
PREPARATION OF READYMIX SYRINGE:
Remove cap from unused syringe and slowly and evenly depress the plunger until equal portions of the base and catalyst components are expressing evenly and simultaneously from their respective openings at the end of the double barrel. The system is now ready for use. Secure the mixing tip onto the bayonet attachment fixture of the barrel syringe. Be sure to align the notch of the mixing tip with the groove on the attachment fixture of the syringe. Give tip a quarter turn to the right to secure tip in place. After use, dispose of the mixing tip and be sure to replace with the original cap locked in place. If the cap is misplaced, a used mixing tip can be left on the syringe until the next use. Do not leave the syringe barrel openings exposed for prolonged periods or during storage. Be careful not to cross-contaminate base and catalyst components at attachment openings.
- Inject auto-mixed Resiment cement into restoration. Keep mixing tip immersed in expressed cement to avoid air entrapment and bubbles.
- Gently Seat the restoration with light, passive pressure and hold until Resiment reaches initial set (Approx. 1.5 minutes). For faster clean-up and to accelerate set time, immediately after seating restoration, light cure all sides of margin for no more than 2 to 3 sec (each side) Cement will reach a semi-solid “gel phase”
- Remove cement with a brush or instrument. Carefully remove excess flash from margin.
- Light-cure each surface of the restoration for 40 seconds. Intra-oral set time for auto cure mode is approximately 5-6 minutes.
CEMENTATION OF LIGHT-TRANSMITTING FIBER-POST
- Preparation of Post Space:
- Etch according to manufacturer’s instructions, and rinse with water.
- Use a large paper point to blot the canal dry leaving the dentin slightly moist.
- Apply a contemporary adhesive according to the manufacturer’s instructions.
- Blot the canal dry for a second time with a new paper point until the canal is dry. It is IMPORTANT that all pooled primers be removed to insure that there is no interference in complete seating of the post.
- Light-cure adhesive according to manufacturer’s instructions.
- Cementation of Post:
- Post must be coated with an adhesive according to manufacture’s instructions.
- (REMEMBER TO FOLLOW INSTRUCTIONS FOR PREPARATION OF READYMIX SYRINGE TO ENSURE PROPER MIXING)
- Dispense a portion of the auto-mixed Resiment onto a lentulo spiral or paper point and coat the walls of the post space and fill the prepared space with cement. Excess cement can be placed upon the shank of the post for secure retention.
- Place the post into the canal gently and maintain firm pressure for 5-10 seconds once the post is seated.
- Stabilize post by light-curing coronal portion for 5 sec.
- Remove excess cement and light-cure for 40 seconds by placing the light tip on the post.
- Intra-oral set time for auto cure is approximately 7-8 minutes.
- Start restorative treatment.
STORAGE: Store at room temperature (20ºC/68ºF-25ºC/77ºF).
PRECAUTIONS: Uncured resins may cause skin sensitizations in susceptible persons. In case of contact, wash skin with soap and water.
