Procedure After removal of the defective restorations, excavation of the caries, and preparation of the cavities (fig. 2), an impression was taken using to the double- mixing technique. For this purpose, the im- pression tray was first coated with Tray-Adhesive (fig. 3). While the assistant filled the impression tray with Honigum- MixStar Putty (fig. 4), the den- tist filled the cavities and cov- ered the occlusal surfaces of the adjacent teeth with bub- ble-free Honigum-Light (fig. 5). During the wash material’s 1:45 minute working time the impression tray was inserted in the patient’s mouth using light pressure and left in situ for at least 3:15 minutes. The acoustic signals of the MixStar- eMotion’s timer are very help- ful for the clinician’s time man- agement. After the setting time had elapsed, the impression was removed from the patient’s mouth, which, particularly in the area of the prepared teeth, must be done parallel to the axis of the teeth. The mate- rial’s putty consistency, which remains in that state even after hardening, makes this process significantly easier. After dry- ing the impression, the result was inspected and the impres- sion stored at a maximum tem- perature of 25°C. The material properties of Honigum-Mixstar Putty and Honigum-Light provided opti- mal results. The impression was a bubble-free, finely detailed re- production of the entire prepara- tion, including any difficult to ac- cess areas and preparation lines. Thanks to the rheologically active matrix of Honigum-Light, which delivers excellent stability yet very good flow characteris- tics, and putty-like characteris- tics of Honigum-Mixstar Putty, which provides patient-friendly resistance, there was no irrita- tion of the sensitive areas in the patient’s mouth due to overflow- ing or running impression ma- terial. Consequently no gagging occurred. The precise reproduction of the preparations, by means of combining the two impression materials, was demonstrated im- pressively by the perfect fit of the final restorations (fig. 7).
