what are the advantages of direct posts
same day post placement, lower cost
what are the disadvantages of direct posts

what are the advantages of indirect posts
more accurate fit, suitable for wider canals, suitable for less than ideal ferrule remaining
what are the disadvantages of indirect posts
required additional appointments, more costly
what are the advantages of metal posts
radiopaque, easily retrievable, better fit to overlaying metal crown
what are the disadvantages of metal posts
poor aesthetics, risk of root fracture, corrosion
what are the advantages of ceramic posts
high flexural strength, greater aesthetics
what are the disadvantages of ceramic posts
difficult retrievability, technique sensitive
what are the advantages of fibre posts
allows light cure through the post, more closely replicates the root modulus
what are the disadvantages of fibre posts
difficult retrievability, technique sensitive, less radiopaque
what are the advantages of parallel posts
less stress on the root, greater retention
what are the disadvantages of parallel posts
less conservative
what are the advantages of tapered posts
more conservative
what are the disadvantages of tapered posts
greater stress on the root, less retentive
