Universal Resin Cement OverCEM SA
\nOverCEM SA is a multifunctional universal cement designed for zirconia, ceramics, metals, lithium disilicate, posts and composites.<\/p>\n
This definitive dual cement eliminates the need to etch the tooth and the use of primer or adhesives, with the advantage of saving time and costs.<\/p>\n
With the smallest self-mixing conical T-Mixer available on the market, it allows a 30% reduction in cement waste compared to standard propeller mixing tips.<\/p>\n
In cooperation with the University of Bologna, a study was carried out to compare the adhesion of zirconia, lithium disilicate, metal, ceramics and posts between OverCEM SA and the most famous self-adhesive cements Unicem 3M, Speedcem Vivadent, Panavia SA Kuraray, Theracem Bisco. The test results of OverCEM SA cement are exciting, thanks to its innovative formula (patent pending) that gives maximum bonding results without orthophosphoric acid, adhesive or primer.<\/p>\n

\nInstructions for use of OverCEM SA Universal Resin Cement:
\nSurface restoration treatments with OverCEM SA:
\nLithium Disilicate and other glass ceramics:<\/p>\n
Use 9% hydrofluoric acid gel for 30-60 seconds.
\nWash with water spray for at least 20 seconds (residual surface acidity can be neutralised with a 5% sodium bicarbonate solution).
\nIf desired, apply a suitable silane primer.
\nFinally, air dry with an oil-free flow.<\/p>\n
Metals, zirconia, polycrystalline ceramics and hybrid ceramics:<\/p>\n
Blasting with aluminium oxide crystals 50-80 \u00b5m at a pressure of 3-4 bar (2 hybrid barceramics).
\nSubsequently perform an ultrasound treatment in distilled water or ethanol for 3 minutes.<\/p>\n
Cemented with OverCEM SA:
\nAfter the crown try-in, clean and sandblast the inner surface of the restoration.
\nExtrude OverCEM SA until both pastes come out of the syringe in equal amounts.
\nInsert the T-Mixer Regular tip into the syringe and apply the OverCEM SA cement.
\nCarefully place the restoration on the die and wait at least 1 minute for the reaction between cement and substrate.
\nLight cure the excess cement for 1-2 seconds to give it a plastic consistency.
\nGently remove cement residues with scaler and dental floss.
\nFinish cement polymerisation (20s per surface with lamp >1000mW\/cm2).<\/p>\n
Cementing of endocanalar posts with OverCEM SA:
\nExtrude OverCEM SA until both pastes come out of the syringe in equal amounts. Mount the T-Mixer Wide + Endo Tip and insert it into the syringe.
\nInject OverCEM SA into the root canal. Slowly withdraw the tip while keeping it submerged and continue injecting the cement.
\nDistribute the cement evenly over the surface of the post making sure that it is completely covered.
\nInsert the post into the root canal making sure that all surfaces of the tooth are covered with cement.
\nRemove the coloured head with a diamond bur and wet the fibres with a thin layer of cement. Then polymerise the cement for at least 40 sec. Direct the flow parallel to the axis of the pole.
\nContinue the restoration by performing the core build-up with the appropriate compound.<\/p>\n
