ABSTRACT:
A moldable material formed over teeth with a second flowable material containing an astringent placed into the impression of the teeth in the moldable material providing retraction and hemostasis at the gum line. A moldable material, preferably a silicone, may contain an astringent such as aluminum ammonium sulfate is made into a mold of teeth. The impression formed in the mold of the teeth is filled with a less viscous or initially flowable material also containing an astringent. The mold with the flowable material is placed over the teeth. The initially flowable material preferably sets into a solid. The flowable material may be made of a condensation silicone having a base and catalyst. The mold helps to apply pressure to the flowable material which is transmitted to the gum tissue resulting in retraction and hemostasis.
