Studies carried out with fiberglass post Whitepost DC and Whitepost DC-E support the higher survival and success rate in dental structures that received intraradicular retainers.
For years, cast metal cores were the most recommended and used to promote retention and reinforcement for the coronal portion through the transmission of forces. This is because, in addition to being relatively inexpensive and technically simple,
they also have a juxtaposed adaptation to the walls of the root canal, which gives them excellent retention.
Research shows that cast metal cores have a high resistance to breakage, but they present irreparable breakage patterns, considering that their modulus of elasticity is higher than that of dentin, which can lead to the loss of the dental element.
Whitepost System – fiberglass post
In this context, the fiberglass post has gained strength in clinical practice, as it shows good resistance, aesthetics, translucency, radiopacity and, furthermore, stands out for containing an elasticity module similar to that of dentin, allowing better distribution of tension through the root dentin, which reduces the risk of breakage.
The FGM fiberglass post system, made of fiberglass composite and epoxy resin, has a variety of diameters together with their corresponding drills, which give the posts a better fit and adaptation to the canal walls.
Even in clinical cases with wide canals, fiberglass posts associated with the direct anatomization technique of the post with composite resin become excellent for avoiding failures and ensuring greater retention in cases of wide roots or with little remnant.
The process consists of placing composite resin on the fiberglass post to reproduce the interior of the root canal. The composite resin occupies the spaces between the canal wall and the post, leaving the assembly juxtaposed to the walls, which increases retention and decreases the thickness of cement to be used, guaranteeing optimal adaptation and longevity to the treatment.
