How Crown is Fitted on Tooth: A Comprehensive Guide
The fitting of a dental crown is a common dental procedure that involves the restoration of a tooth that has been damaged, decayed, or lost. A dental crown, also known as a tooth cap, is a custom-made covering that fits over the entire visible part of a tooth. This article aims to provide a comprehensive guide on how a crown is fitted on a tooth, from the initial consultation to the final restoration.
Initial Consultation and Diagnosis
The process of fitting a dental crown begins with an initial consultation with a dentist. During this visit, the dentist will examine the affected tooth and determine the need for a crown. X-rays and other diagnostic tools may be used to assess the extent of the damage and to plan the treatment. The dentist will also discuss the options available and answer any questions the patient may have.
Preparation of the Tooth
Once the decision to proceed with a dental crown is made, the next step is to prepare the tooth for the crown. This involves the following:
1. Anesthesia: Local anesthesia is administered to numb the area around the tooth to ensure the patient is comfortable during the procedure.
2. Shaping: The affected tooth is reshaped to accommodate the crown. This may involve the removal of a small amount of tooth structure to create space for the crown.
3. Impression: An impression of the tooth and adjacent teeth is taken. This impression is used to create a model of the patient’s mouth, which is then used to fabricate the custom crown.
Creating the Crown
After the impression is taken, it is sent to a dental laboratory where the crown is created. The process typically involves the following steps:
1. Modeling: The impression is used to create a model of the patient’s mouth.
2. Fabrication: The dental lab technician uses the model to create the crown, which is made from materials such as porcelain, ceramic, or metal.
3. Shading and Contouring: The crown is then shaded and contoured to match the color and shape of the surrounding teeth.
Placement of the Crown
Once the crown is ready, it is placed on the prepared tooth. This process involves the following:
1. 试戴: The crown is temporarily placed on the tooth to ensure it fits properly and to check the bite.
2. Adjustments: Any necessary adjustments are made to ensure the crown fits comfortably and functions correctly.
3. Bonding: The crown is permanently bonded to the tooth using dental cement.
Aftercare and Maintenance
After the crown is fitted, it is important to maintain good oral hygiene to ensure the longevity of the restoration. Patients should brush and floss regularly, avoid hard or sticky foods that can damage the crown, and attend regular dental check-ups to monitor the condition of the crown and the surrounding teeth.
In conclusion, the fitting of a dental crown is a meticulous process that involves several steps from preparation to final placement. Understanding how a crown is fitted on a tooth can help patients make informed decisions about their dental care and ensure the success of the procedure.
