No, this a dual-cure material. You can let the material self-cure or tack-cure prior to removing excess cement.
No. Nexus™ RMGI is intended for use as a permanent dental cement. It is indicated for the following indirect restorations: Cementation of metal-based inlays, onlays, crowns and bridges Cementation of resin inlays, onlays, crowns and bridges Cementation of all ceramic inlays Cementation of high strength (zirconia based) all ceramic crowns and bridges Cementation of metal, ceramic and fiber posts
Yes. Nexus RMGI is contraindicated for pulp capping. In addition, this product is not to be used on veneers or all ceramic/porcelain crowns and onlays. In rare cases, the product may cause sensitivity in some people. If any such reactions are experienced, discontinue the use of the product and refer to a physician.
No. Automix tips are for single patient use only, to prevent cross-contamination between patients.
Prepare tooth in usual manner. For pulp capping use calcium hydroxide or other suitable pulp capping material. Remove provisional restoration. Clean the preparation with pumice and water. Rinse thoroughly with water. Air dry preparation (do not desiccate). The preparation or cavity should be just dry enough that the surface has a slightly glossy appearance. Over drying can lead to post-operative sensitivity. Try in restoration to ensure proper fit. Adjust if needed. Thoroughly clean the bonding surfaces of the restoration. Remove the syringe from the foil pouch. Note the date the syringe was removed on the syringe label. Remove the sealing cap from the syringe. Check the syringe openings for blockage; remove any paste plugs. Before the first use or after a long interval between uses, squeeze out a small quantity of paste onto a pad to equalize the base and catalyst paste in the syringe. Discard the paste which has been squeezed out. Attach a new mixing tip and secure it by turning it to the right. Squeeze out and discard a peppercorn-size quantity until an evenly mixed paste in a homogenous color flows out of the tip. The paste requires a certain amount of time to flow through the mixing tip. The flow through speed cannot be accelerated by increasing the pressure on the plunger. As soon as the pressure on the plunger decreases, the material flow stops and the paste begins to set up. Do not use force to press out paste that has set as this could cause damage to the mixing tip and the syringe. Dispensing of the material can be done as follows: Inlay/Onlay – Dispense the cement directly into the cavity preparation covering all surfaces. Seat the restoration gently onto the tooth prep, allowing the cement to flow from all sides. Crown – Dispense the cement directly into the restoration, covering all surfaces. Seat the restoration gently onto the tooth prep, allowing the cement to flow from all margins. Post – Prepare the post space. Size and fit the post. Dispense the cement onto the post or directly into the canal space. Seat the post and vibrate slightly to avoid trapped air. Allow the cement to slowly flow from the canal space. When the restoration is properly seated, remove excess cement. Excess cement is best removed in its gel state with a scaler or explorer. Gel state can be achieved by tack-curing excess with a light for approximately 2-3 seconds, or by allowing the cement to self-cure for approximately 2’-2’30” after application. Finish the restoration and check occlusion when material has completely set. Material should completely set within 4’30” after placement in the mouth. Remove the used mixing tip and replace it with the sealing cap. Do not leave the used mixing tip on the syringe for a long period of time. When only a small amount of paste remains in the syringe, the paste may not be dispensed from the mixing tip.
When the restoration is properly seated, remove excess cement. Excess cement is best removed in its gel state with a scaler or explorer. Gel state can be achieved by tack-curing excess with a light for approximately 2-3 seconds, or by allowing the cement to self-cure until it feels rubbery.
Set time is less than 4’30” at oral temperature. These times may vary based on storage conditions, temperature, humidity, and age of product.
This product is designed to be used at room temperature.
Yes. If stored in a cooler, allow the product to reach room temperature prior to use.
Shelf life at room temperature between 4°C (39°F) and 25°C (77°F) is 18 months.
Ambient temperatures greater than 25°C (77°F) may reduce shelf life.
See outer package for expiration date. Keep product in foil package until initial use. Once the foil pouch is opened, use the product within 4 months and prior to expiration date.
Yes. Do not allow the pastes to dry out. Store with cap securely attached to the syringe. Leaving a used mixing tip on the syringe as a cap until the next application may result in evaporation and drying of the paste (not recommended).
Yes, uncured methacrylate resin may cause contact dermatitis and damage the pulp for some patients. Avoid contact with skin, eyes and soft tissue. Wash thoroughly with water after contact. Get medical attention for eyes. Do not take internally.
With Nexus Technology’s proprietary redox initiator system, Nexus RMGI provides users with optimal gel state, predictable gel-set times and optional tack-curing, which ensure consistent cleanup each and every time.
Nexus RMGI utilizes a unique dual adhesive system to achieve enhanced bond strength to tooth structure (dentin/enamel) and other dental substrates.
You can tack-cure (1-2 seconds) Nexus RMGI immediately after placement to hasten gel state or you can also allow Nexus RMGI to self-cure (minimum of 1.5’) to reach its gel state.
Nexus RMGI is the new resin modified glass ionomer (RMGI) luting cement with: Best cleanup for an RMGI Consistent gel-set times Optimal gel state window Optional tack-curing Highest bond strengths for an RMGI: Dual-adhesive system 50-80% greater than market leader for metal and zirconia crowns Exceptional performance and physical properties Flexural and compressive strengths are 50% higher than those of leading competitor Ultra low film thickness (<10µ) Increased radiopacity (217% Al)
With Nexus Technology’s proprietary redox initiator system, Nexus RMGI provides users with optimal gel-set times and optional tack-curing, which ensure consistent cleanup each and every time.
Tack-curing the cement hastens the gelling of the cement. Once the cement has gelled, it can no longer be manipulated.
Radiopacity is measured by taking an X-ray of a dental product alongside aluminum and then comparing the X-ray absorbing power (optical density) of both X-rays. If the X-ray absorbing power for the dental product is the same as that for aluminum, then the radiopacity of the dental product is 100% of aluminum. If the X-ray absorbing power for the dental product is 2 times as strong as that for aluminum, then the radiopacity of the dental product is 200% of aluminum. Dentin has a radiopacity of 100% of aluminum and enamel has a radiopacity slightly less than 200% of aluminum. To be called radiopaque, the radiopacity of the cement must be equal to or greater than that of dentin (≥ 100%). Generally, a cement with a radiopacity of less than 100% of aluminum is called radiolucent (or not radiopaque). Nexus RMGI is 217% of aluminum.
Root canal tips are used to dispense precise amounts of cement onto the post or directly into the canal space. They are not to be used to seal root canals.
Root canal or intraoral tips can be used. The root canal tips have a narrower opening which allows for more precise dispensing of cement than an intraoral tip could provide
No. Root canal sealing is not an indicated use for Nexus RMGI.
