The teeth were to be restored with ceramic restorations. A spe- cial challenge was the patient’s pronounced gagging reflex. In order to take an accu- rate impression of any cavity preparedaccordingtominimally- invasive principles, the im- pression material must exhibit specific properties. The wash material should be applicable without bubbles, remain in situ on the preparation without slumping, have optimal flow characteristics under pres- sure, and provide precise detail reproduction. The tray material should support the properties of the wash material. The preferred tray material should be one with a true putty consistency and with optimal resistance when posi- tioned, in order not to trigger the patient’s gagging reflex. Both materials should be suitable for the double-mixing technique with matching setting times. For the double-mixing tech- nique, DMG’s Honigum-MixStar Putty and Honigum-Light were used because these materials fulfilled all the above conditions. The materials were mixed in the MixStar-eMotion automatic mix- ing unit, which is programma- ble for working time and setting time in the mouth. In order to guarantee stabil- ity of the impression material upon removal from the mouth, a non-perforated impression tray, coated with DMG Tray- The perfect answer to gagging Dr Manuel Kalo presents a simple solution to help patients prone to gagging during the impression taking process Fig. 2 Preparing the cavities Fig. 3 Applying DMG Tray-Adhesive Fig. 4 Hygienic filling of the impression tray, using Honigum-MixStar Putty Fig. 1 Initial situation
