[Biocem--a new material for retrograde root filling. The 5-year clinical results]

This paper describes the application of a new material, Biocem, for retrograde root canal filling. A total of 234 roots in 222 teeth were treated during the period 1987-1992. Biocem consists of two components and once mixed, the autopolymerisation results in a three-dimensional structure. The biomechanical and histologic properties and a clinical longterm follow-up confirm the optimal qualities of this material. It fulfills the requirements in regard to biocompatibility, watertight sealing and application. The material proved superior in comparison to conventional materials and ceramics. The evaluation of the results are most encouraging.
