Precious metal post & core custom implant abutment gold alloy
The gold alloy is an ideal material to make post and core. Its modulus of elasticity and coefficient of thermal expansion are basically match with enamel. The strength is enough to meet the general occlusal force.
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.
