Ketac Cem Glass Ionomer Luting Cement, developed by 3M ESPE, stands as a reliable and versatile solution in the realm of dental care. This powder/liquid glass ionomer cement has proven its mettle in securely fixing a wide array of dental restoration materials. Its multifaceted attributes make it an indispensable choice for dental practitioners seeking optimal performance in their procedures.
This dental cement finds its application in various clinical scenarios. It is well-suited for cementing inlays, onlays, crowns, and bridges, whether they are constructed from metal, porcelain-fused-to-metal (PFM), all-alumina, or all-zirconia strengthened core ceramics. Furthermore, it serves the purpose of cementing posts and screws, making it an invaluable tool in restorative dentistry. Orthodontic bands also benefit from its adhesive properties, as does cavity lining, ensuring comprehensive utility in dental practices.
One of its standout qualities is its high fluoride release, contributing to enhanced oral health by promoting enamel remineralization and strengthening teeth. Additionally, Ketac Cem Radiopaque forms strong bonds with both enamel and dentin, significantly reducing the risk of microleakage, a common concern in dental restorations. Its excellent biocompatibility ensures patient safety and comfort during and after dental procedures.
In terms of practicality, this cement boasts an extremely low film thickness, optimizing the fit and marginal integrity of restorations. This feature is crucial for ensuring a precise and snug fit of dental prosthetics. Its mechanical properties are also commendable, allowing for use in long-spanning bridges, a testament to its durability and reliability in challenging clinical scenarios.
Moreover, Ketac Cem Radiopaque offers high radiopacity, aiding in post-operative assessment and ensuring that dental practitioners can monitor the restoration’s integrity effectively.
When it comes to application, the steps are straightforward. The tooth preparation process precedes the cementation, which involves mixing the powder and liquid components to achieve the desired consistency. The resulting mixture is applied thinly and evenly to the inner surface of the restoration, ensuring a secure bond without applying excess pressure during seating.

Powder- Glass powder, Water, Polycarboxylic acid
Liquid- Tartaric acid, Pigments, Conservation agents
Working time incl. mixing- 3min
setting time- 7 min (from the start of the mix).

1 x 33g Powder
1 x 12ml Liquid
1 x Spoon
1 x Mixing pad

STEP 1- Prep the tooth. Thoroughly clean the tooth.
STEP 2- Gently dry the preparation. Do not over-dry.
STEP 3- Dry the restoration with air.
STEP 4- Shake powder in a bottle to fluff. Dispense 1 level scoop of powder. Dispense 2 drops of liquid. Add powder to liquid in one portion and mix. When properly mixed, the material should stretch 1/2 from the pad or slab.
STEP 5- Place a thin, even layer of cement on the inner surface of the restoration. Do not use the mixture if it has lost its gloss.
STEP 6- Seat the restoration without pressure and remove excess.
