The central longitudinal axis of Hi-Rem Endodontic Post is made of soft polymer macro-fiber, placing in this position doesn’t affect the resistance of the post, because the stresses are minimal (neutral axis)
The clinical advantage of Hi-Rem Endodontic Posts:
When the teeth have a moderate residual coronal structure or when more than one post is inserted in the canals of the same tooth, the coronal part of the post may interfere with either the residual dental structure or with the other post: the conicity of this portion has the effect of considerably reducing the interference in both cases, improving the insertion of the post, even in teeth with a considerable amount of residual coronal dentin.
