Cobalt-Chromium alloy post & core custom implant CoCr abutment
The cast metal post & core has good physical and mechanical properties, and very easy to be machined into precise shape. It is always been used to repair residual roots.
A prefabricated post is quicker to fit as there is no extra laboratory work needed and they come in various shapes and sizes. A cast post (or custom post) may be used in the cases where a prefabricated post is not suitable.
The laboratory-cast posts are usually made of carbon-fibre or stainless steel. This involves taking a mould of the inside of the canal, which is then sent to the dental lab so that a fitted post can be created. These usually include a core. Once the custom post and core is fitted into place, a mould can be taken in order to create a fitted crown.
The prefabricated post can be fitted directly after root canal treatment. When the root canal has been cleaned, the canal is filled with gutta percha, which is a filling material. Some of this material is filed down, removed and shaped in order to accommodate space for the post. Once this has been placed, a core, or build up material is shaped around the post. With this in place, the crown can be attached on top of the post and core.
