About post and core accessories
Post and core accessories are the drills that prepare a post space, each made for one post size and matched to the diameter of that post.
A core is the foundation restoration that rebuilds enough of the crown of a tooth to carry the final restoration. A post is a rod, usually of metal or fiber-reinforced composite resin, fitted into a prepared root canal; combined with a core it provides retention and resistance for a crown.
The main purpose of a post is to retain the core; a published review notes that posts do not reinforce the tooth.
How core materials, posts and pins differ
- Core materials — The material that rebuilds the missing part of the tooth and gives the final restoration its shape and hold.
- Posts and pins — A post goes into the root canal and holds the core; a pin goes into dentin to add retention. A narrative review found similar survival for fiber posts and for prefabricated and cast metal posts.
- Post and core accessories — The drills that shape the post space to a given post size.
What to look at when choosing
Post material: metal, or fibers of carbon, glass or quartz in a resin base. The first fiber posts were radiolucent; radiopaque fiber posts followed.
Post shape and size: posts are tapered and smooth or parallel-sided and serrated, and come in numbered sizes.
Curing of the core material: light-cured composite is placed in layers of about 2 mm, and dual-cure resins were developed for deeper applications where light penetration is limited.
FDA class: metal root canal posts and retentive pins are Class I devices (21 CFR 872.3810 and 872.3740). Tooth shade resin, the material of composite cores, is Class II (21 CFR 872.3690).
