Sorensen and engelman in 1990. Smaller dimensions are associated
with a greater risk of failure.
CASe 1
The tooth with extensive tooth loss, but enough pericervical dentin
for restoration to be builds up using a post. The caries was excavat-
ed, FRC poster post used and a direct composite buildup done.
using a crown would have reduced the pericervical dentin making
the structure weaker (Figures 3a, 3b and 3c)
Adhesive dentistry helps us to avoid posts in posterior teeth as
one gets enough support for restorations from various bonding sur-
faces

FIG 3c A young female presented with extensively damaged molars (Figure
4a). upon finishing of endodontics therapy and
excavation of caries it was seen that there was
enough enamel and dentin for achieving ade-
quate bonding (Figure 4b).
hence no need for any post. The case was
build up with direct composites and restored to
its function (Figures 4c, 4d and 4e).
A post should be used only when there is
insufficient tooth substance remaining to sup-
port core material or the final restoration. The
height of the post should always be the same or
greater than that of the future crown, and its
width should be established by the width of the
canal after root canal treatment. increasing post
diameter in an effort to increase retention is not
recommended, as this creates unnecessary weak-
ening of the remaining tooth structure.
