    Top 5 product test drives of 2017

    Dr. Flucke breaks down the products that blew him away this year.



    Rhondium OVC3

    The OVC3 (One Visit Crown) from Rhondium is one of the more interesting ideas I’ve seen in the last few years. As bonding and esthetics in porcelain have evolved over the last 20 years, we’ve seen our preparations for fixed prosthetics change as well as the strength we expect to achieve with bonded restorations.

    The creation of highly esthetic porcelain such as lithium disilicate has allowed for preparations that terminate at the height of the gingiva or even supragingivally. This means margins are much easier to detect and restorations are much easier to bond, since contamination from blood and sulcular fluids is much less of a problem. This entire progression has allowed for preparations to be much more conservative while making the bonding process stronger and much more predictable.

    Rhondium steps into this space with a unique idea of providing lab-made, prefabricated porcelain crowns that can be bonded onto conservative preparations in a unique one visit crown procedure with no need for CAD/CAM.

    The system comes prepackaged with everything needed to perform the restoration. It includes a size gauge, specially contoured matrix band, one-of-a-kind “stretch wedges” that provide greater interproximal separation than standard section matrix “rings,” and the OVC3 itself.

    The restorations come in a variety of sizes for any posterior tooth and the size is determined by a “size selector key” that shows the practitioner the proper width to use. The OVC3is available in either lithium disilicate or a hybrid ceramic material. The process eliminates lab fees, temporaries and second appointments, but without the cost of CAD/CAM.
