ChemFil Rock

    Glass ionomer restorative materials are used in a variety of indications where their specific clinical advantages make them the material of choice.  According to general practitioners, the advantages of glass ionomers (GI) include

    • the lack of need for an adhesive
    • bulk cavity filling
    • easy finishing.

    Dentists reach for glass ionomer restoratives more every year because of GI’s superior performance in pediatric, geriatric and many other cases.  However, in class II restorations the brittle nature of these materials has so far limited their use in permanent dentition to long-term provisional fillings.

    There is therefore a challenging demand for a glass ionomer material which combines the handling and application properties of today’s GI with higher resistance to bulk fracture.   ChemFil Rock’s new and unique formulation contains zinc-modified reactive glass fillers.  This promotes a simpler placement process, earlier toughness build-up and superior resistance to fractures.

    Professor Trevor Burke of Birmingham Dental School conducted a PREP Panel evaluation for the NEW ChemFil Rock glass ionomer restorative from DENTSPLY from July 2011.

    73% (n=8) of the evaluators stated they were satisfied with ChemFil Rock. Eight (73%) evaluators also stated they would purchase the material if available at an average price and the same number would recommend ChemFil Rock to colleagues. Changes to set time, capsule redesign and shade alteration were suggested to further improve  the acceptability of the material.

    ChemFil Rock study data

    The results from the in-vitro investigations by Frankeberger, Lach and Latter (2009) suggest higher strength, superior fracture and wear resistance of ChemFil Rock in class II restorations under occlusal load compared to currently available leading GI restorative brands. According to chewing simulation ChemFil Rock provides posterior restorations with at least 2 years of survival under simulated clinical conditions. Considering the principal advantages of GIs ChemFil Rock is a further step towards an easy, economic, and reliable basic restorative material especially for posterior teeth.

    Specialists in paediatric dentistry use glass ionomer on uncooperative patients

    During the IAPD (International Association of Paediatric Dentistry) congress in Athens last year, 230 international specialists in paediatric dentistry from 50 different countries took part in market research to evaluate material choice for direct restorations in different clinical situations. The research concluded where there is a high risk of contamination, 73% of respondents confirmed that they use glass ionomer and 12% use compomer.


    DENTSPLY’s glass ionomer ChemFil Rock is an ideal material when an adhesive procedure is not possible as it can be bulk filled, sculpted immediately and self cures without the need for conditioning or coating. For children with good moisture control DENTSPLY’s compomer restorative, Dyract Extra, is an ideal solution due to its continuous fluoride release resulting in long term caries preventive effect and its tooth coloured aesthetics.
