G-CEM LinkAce

The new strength in self-adhesive cement

G-CEM LinkAce is stronger Now offering comparative physical properties to current adhesive resin cements, G-CEM LinkAce is the next evolution in easy-to-use, versatile, self-adhesive resin cements.

Designed with a highly efficient self-cure polymerisation reaction, G-CEM LinkAce always delivers high bond strengths and exceptional physical properties, even without light activation.

G-CEM LinkAce is suitable for bonding and cementation of indirect metal, PFM, composite, zirconia, alumina and all-ceramic restorations (including posts), and retains the simple-to-use handling characteristics popularised by the previous generation of self-adhesive resin cements.

The transmission of light has never been a certainty… This experiment was designed to simulate a clinical situation. The light intensity of a LED curing unit was measured following its transmission through different restorative materials. Light intensity reduces drastically in each case, showing the importance of an efficient self-cure polymerisation.

G-CEM LinkAce

G-CEM LinkAce Innovation Advanced resin polymerisation initiation systems;

patented self-cure initiation technology gives surety of a complete cure, high strength and strong adhesion even without light activation. As the majority of indirect restorations significantly limit transmission of curing light, a strong dark cure reaction offers security to ensure clinical durability of the cement. The new initiation system technology also introduces a high level of chemical stability to give G-CEM LinkAce a 2-year shelf life without refrigeration.

Finer glass fillers; used to improve flow characteristics, physical properties and cement wear resistance while decreasing cement film thickness to just 3 microns.

Higher polymerisation conversion; gives superior colour stability and stain resistance, as well as helping achieve more durable adhesion over time.

Proprietary phosphate ester monomer; enhances the level of adhesion to a variety of substrate surfaces.

Higher strength: self cure or light cure

G-CEM LinkAce Simplicity

G-CEM LinkAce VersatilityStrong chemical bonding and self-curing capabilities are essential for durable bonding of indirect metal, zirconia and opaque ceramic restorations.

ChallengeIn many clinical cases, light simply doesn’t penetrate through indirect restorations, compromising polymerisation and leading to poor bonding and poor physical properties with self-adhesive resin cements.

SolutionG-CEM LinkAce achieves strong chemical bonding and provides exceptionally reliable self-curing capabilities with all materials, thanks to its unique initiator system. Even without light activation, G-CEM LinkAce will provide strong durable adhesion.

No need for etching or bonding steps. Clean the prepared tooth with pumice and water, rinse and gently dry.

One step automix dispensing. Where required, pretreat the internal surfaces of the restoration, then extrude cement directly without over filling

G-CEM LinkAce

Ideal consistency for easy excess removal. To remove excess cement, either light cure for 1 second or allow the cement to self cure. Remove excess when the cement feels rubbery.

Guaranteed stability, 2-year shelf life. No refrigeration needed.

Fluoride release and aesthetic results. Light cure for 20 seconds each surface or wait 4 minutes for self cure set before final finishing.

A chemical bond to zirconiaChallengeZirconia restorations offer many advantages but bonding to zirconia remains challenging.

SolutionG-CEM LinkAce contains a proprietary phosphate ester monomer that chemically bonds to zirconia for a strong and stable bond. Combined with the enhanced physical properties and higher degree of conversion, this results in a stronger and more durable bond to zirconia without the need for a separate primer.

G-CEM LinkAce ReliabilityG-CEM LinkAce gives you a consistently high degree of polymerisation – ensuring optimal colour stability, bond strengths and aesthetics for all ceramic restorations.

ChallengeCementation of all-ceramic crowns requires a material with extra bonding efficacy and high colour stability for a superior aesthetic result.

SolutionG-CEM LinkAce high polymer conversion gives increased durability and high bond strengths, preventing loss of retention. G-CEM LinkAce exhibits minimal water uptake, is HEMA-free and delivers reliable colour stability.

G-CEM LinkAce high polymer conversion is important for colour stability when bonding highly aesthetic restorations.

Unsurpassed wear resistanceChallengeExposed cement at margins wears over time and can lead to chipping of ceramic restorations.

SolutionG-CEM LinkAce offers high wear resistance due to its small and homogeneously-distributed filler particles, minimal water uptake and highly-polymerised resin matrix.
