How do they make a tooth crown? The process of creating a dental crown is a precise and meticulous procedure that involves several steps to ensure the final restoration is both functional and aesthetically pleasing. A tooth crown, also known as a cap, is a custom-made cover that is placed over a damaged tooth to restore its shape, size, strength, and appearance. This article will delve into the various stages of crown fabrication, from initial consultation to the final placement of the crown.
1. Initial Consultation and Examination
The journey of creating a tooth crown begins with a consultation with a dentist. During this visit, the dentist will examine the affected tooth, assess the extent of the damage, and discuss the treatment options with the patient. If a dental crown is deemed necessary, the dentist will take impressions of the tooth and surrounding teeth to create a precise model for the crown’s construction.
2. Preparing the Tooth
Once the patient has agreed to proceed with a dental crown, the dentist will prepare the tooth for the crown. This involves removing a small amount of the tooth’s structure to make room for the crown. The dentist will also take additional impressions of the prepared tooth to ensure the crown fits perfectly.
3. Creating the Temporary Crown
After the tooth is prepared, a temporary crown is placed to protect the tooth while the permanent crown is being made. This temporary crown is usually made of a tooth-colored plastic and is designed to last until the final crown is ready.
4. Fabricating the Crown
The impressions taken during the initial visit are sent to a dental laboratory, where technicians use them to create the custom dental crown. The crown is typically made from porcelain, ceramic, gold, or a combination of materials that match the patient’s tooth color and provide the necessary strength. The fabrication process involves the following steps:
–
4.1. Impression Material
The impression material is placed into the mouth to capture the shape of the prepared tooth and the surrounding teeth. The material hardens to form a detailed mold of the tooth.
–
4.2. Stone Model
The dental technician creates a stone model from the impression, which serves as a base for constructing the crown.
–
4.3. Wax Up
A wax-up is created to represent the final shape of the crown. This allows the technician to visualize the tooth’s appearance and ensure proper occlusion (bite) with the opposing teeth.
–
4.4. Crown Fabrication
The wax-up is used to create a model of the crown, which is then cast in metal or ceramic to create the final restoration.
5. Fitting and Placement
Once the dental crown is ready, it is sent back to the dentist’s office. The dentist will check the fit of the crown, make any necessary adjustments, and then cement it into place over the prepared tooth.
In conclusion, the process of making a tooth crown is a detailed and technical procedure that requires collaboration between the dentist and dental laboratory. The end result is a custom-made restoration that restores the function and appearance of the affected tooth, enhancing the patient’s oral health and confidence.
