Flexofile: Recommended use

Flexofile is suited for both straight canals and slightly curved canals. The flexofile prepares dentin effectively both in filing motion (up and down) and when rotated. In slightly curved canals the recommended techniques are continuous rotation (lower picture) when the resistance is small and balanced force (upper picture) against greater resistance. Use of continuous rotation is limited as compared to reamers because of the screwing effect typical of K-files.
