Objective: EverStick glass fibre posts have been advocated for a new method of a direct post and core fabrication. The EverStick posts have adhesive surface and are flexible before curing therefore can be shaped individually. The purpose of this article is to describe a new technique of direct composite resin crown fabrication on a custom made EverStick root canal post.

 

Methods: At first a rubber dam isolation was achieved and the EverStick post was fabricated following manufacturer’s instructions (Figure1 A, B, C, D, E). The crown fabrication started from the palatal layer of composite resin (Gaenial JE, GC) which was applied by means of a silicon index and light cured for 20 seconds (G-Light, GC).A dual cure self-adhesive resin cement (G-CEM Link Ace A2, GC) was used to cement the post and light cured for 40 seconds Figure(2A). Two further layers of Gaenial in AO2, A2 shades were placed to obtain the dentin shape and shade of the crown (Figure2B).

For the enamel layer of the restoration Gaenial BW shade was used (Figure2C). Each layer was light cured separately for 20 seconds. The restoration was polished with diamonds (NTI-KAHLA GmbH, Germany) under water cooling. The final gloss was achieved by means of Soft-Lex discs (3M ESPE, USA) and a polishing paste (Gradia diapolisher, GC).

 

Results: The results achieved after 3 days (Figure 2D) and 12 months (Figure 2E) showed satisfactory aesthetics and marginal integrity of the restoration.

 

Conclusion: Direct composite resin crown fabrication on a custom formed root canal post could be used as an economical and conservative treatment option.
