LARSSON, Folktandvården Västerbotten - Norsjö, Umeå University, 935 32 Norsjö, Sweden, and M. MOLIN, Umeå University, Sweden Objectives: Interest in tooth-colored, non-metallic prosthetic replacements has increased dramatically during the last decade. A new technique for manufacturing root canal posts was recently introduced, the Composipost®, made of pre-fabricated carbon fiber epoxy. It is commonly used in Europe for the restoration of endodontically treated teeth and it is known in the United States as the C-Post. The internal structure of this post consists of long high-performance carbon fibers, unidirectionally and equally stretched, with a fracture resistance higher than most metals. It is described to have a modulus of elasticity that is almost identical to that of dentin. This is thought to cause less stress in the tooth and therefore resulting in fewer root fractures. The purpose of this study was to evaluate the clinical performance of Composipost® root canal post within the regular dental care system of Sweden. Methods: The dental records in the public dental health clinics within the county of Västerbotten, Sweden, was investigated and all Composipost® root canal post cemented during a four year period were included. A total of 526 patients were treated in 642 teeth by forty-six different dentists. This evaluation describes the results after a mean follow up time of 7.2 years with a range from 5.0 to 9.2 years after cementation. Results: Complications were seen in more than 10% of the cemented posts. The most common complication was the loss of retention of either the post or the crown or both. In some cases the same post lost retention more than once. Conclusions: The present seven-year findings cannot allow a definitive judgment with regard to long-term clinical quality but indicates that the Composipost® might show a higher percent of dislodgment than conventional cast posts. Further controlled studies are necessary to achieve improved knowledge of the long-term success of prefabricated root canal posts.
