RESTORING SEVERAL TEETH SIMULTANEOUSLY USING A SILICONE KEY BY CAMOUFLAGE

Abstract

Introduction. When restoring the teeth, the doctor meets with such difficulties as
impossibility to control the thickness of the layers of the composite material being
superimposed, the relief of the palatine and chewing surfaces is not quite optimal, a great
deal of time and so on. These disadvantages can be avoided when using the technique
using a "silicone key". Silicone key - the method of restoring the anatomical shape of
the tooth with the help of a silicone impression. The key is made on a gypsum model by
restoring the defect with wax. The key is cut in horizontal and vertical planes. For
accuracy, it should cover the gum and adjacent teeth. The key is used both on the frontal
and lateral groups of teeth. The key is superimposed on the tooth, and we get a "guide
to action". On the cutting edge and on the approximate surfaces of the silicone matrix is
applied a composite of the enamel shade, on the palatal surface - a dentine shade. The
structure of the tooth is restored successively from the oral surface to the vestibular. This
technique is also used to treat latent forms of caries in the group of chewing teeth (IROZ
tends to 0). The cavity is filled with a composite, and the last portion is formed by a key,
excluding the influx of material by creating in the key off-take channels. The
introduction of the "silicone key" method into clinical practice will not only save the
doctor's time, but also prevent possible complications. This method allows you to obtain
the optimal relief of the palatine and occlusal surface, virtually no need for occlusal-
articulatory correction. The technology of making the key is extremely simple, but it
allows to increase ergonomic indicators at the dental reception.
