"Cobra Conic" quartz fiber dental posts - combined set

 NEW! Now, "Cobra Conic" dental posts are made of quartz fiber in epoxy resin matrix.

The quartz fiber posts are the newest model of posts Micro.Medica offers. This type of crystal is the result of many years of research and experimentation, and the use of high purity raw materials and innovative production technology has resulted in a product with unique properties.

Through a perfect blend of quartz fiber and epoxy resin, a post of exceptional transparency and outstanding mechanical properties has been created.

The rendering process of this kind of transparency is extremely difficult and complex when epoxy resin is used. This is why many post manufacturers, who do not have the necessary knowledge or technology, avoid them, using instead vinyl or polyester resins, with which they achieve a discrete transparency, but which have significantly lower chemical and mechanical properties than epoxy resin.

The elasticity modulus close to that of dentin makes epoxy resin the most suitable material to achieve a good strength of the reconstruction.

Cobra Conic Posts The post body is tapered.

The occlusal end is provided with retainers, facilitating the reconstruction of the dental abutment/blunt with composite while saving material.
