Background
When the tooth is not provided with enough tooth structure in the oral cavity to keep the crown due to decayed tooth, traumatic fracture and the like, the post-core repairing technology is a common repairing method for effectively constructing the tooth structure and repairing large-area tooth defects. In many cases, good retention cannot be obtained with a full crown alone due to the small amount of tooth tissue remaining. In order to increase the retention, the retention is obtained by inserting a portion of the prosthesis, called post, inserted in the root canal and the portion of the prosthesis fixed to the post and replacing the missing tooth is called core. Core-pile repair is commonly referred to as "base repair".
In root operations, a dentist typically removes the nerve of a tooth with a dental drill, leaving a hole in the tooth, the root canal having an irregular structure, and the hole in the tooth after root removal is also typically irregular, requiring the provision of a custom-made post to match it.
In designing the core, the general operation is that a dentist provides an impression of a tooth near a hole, a dental technician pours a tooth model (such as a plaster model) according to the impression, first manually manufactures a wax-type core, then inserts the wax-type core into the tooth model to match with the hole, finally sprays a shading layer on the matched wax-type core, scans the wax-type core into a computer, and performs computer-aided design and processing to obtain the core.
