Constic - The self-etching and self-adhesive filling material A case presentation by Matthias Hodecker and Julia Gerke B ecause of today’s wide selection of bonding systems with compli- cated work processes the de- sire to simplify working steps during restorative treatment is becoming greater than ever before. Particularly in the case of small Class I restorations, as well as fissure sealing and lin- ing, which can be performed relatively quickly, prepara- tory steps such as etching and bonding protract the work- ing time unnecessarily. At the same time, they increase the number of possible sources of error since, if certain working steps are neglected, the dura- bility of the restoration can be drastically reduced. Many dentists would like to have fewer work steps required, in order to be able to work more reliably and focus primarily on the resto- ration. This can be achieved through the use of self-etch- ing and self-adhesive synth- etic materials. Constic is the new self- etching and self-adhesive flowable composite from DMG, which combines etch- ing, bonding and filling in one step and features superior ad- hesion to enamel and dentine along with good aesthetics. Case study In the following case, a small and inadequate Class I resto- ration on tooth 17 can be seen (Fig 1). Procedure After preparing the cavity, it is initially recommended to clean the tooth, remove any debris using water-spray and blow it dry (Fig 2). Then an ap- proximately 0.5mm thick layer of Constic flowable composite is applied to the cavity using the Luer-Lock-Tip and mas- saged in for 25 seconds using a brush (Figs 3&4). Thereafter any excess should be removed (Fig 5). Then the layer is light- cured using a polymerisation light for 20 seconds (Fig 6). The actual restoration is then performed. For the resto- ration, the material is applied in layers that are a maximum of 2mm thick (Fig 7). The low- viscosity and uniform consist- ency of Constic ensures that the restoration has no trapped air or marginal gaps. This is facilitated by the fact that no additional bonding materials are used. Each layer is light- cured for 20 seconds (Fig 8). Using a dental probe, a high-quality aesthetic fissure surface can be achieved prior to final curing (Fig 9). Apart from the Luer-Lock-Tips and the brush, which are in- cluded in the set, few addi- tional modeling instruments are required. Thus sterili- sation costs and instrument wear are kept to a minimum.
