Before installing dental crowns, the doctor carefully analyzes the condition of the patient’s oral cavity. If the client has contraindications to the installation of crowns, the doctor looks for alternative treatment methods and carries out mandatory sanitation of the oral cavity.
It is prohibited to install crowns in the following cases:
- Presence of bite problems that require correction
- Preserved pulp in children and adolescents, which can cause problems in the future
- Pathological abrasion of hard tooth tissue
- Active periodontal inflammation associated with infection
Dentists also stipulate additional contraindications to the installation of ceramic crowns. Such limitations include low clinical height of a natural tooth or deep bite.
Cons of ceramic crowns
The main disadvantage of the structures is considered to be insufficient strength in comparison with metal analogues. It is for this reason that they are often used for the restoration of anterior teeth.
Other disadvantages include:
- The need to grind teeth before installation
- Risk of tooth destruction under the crown due to untreated root canals, caries or pulp burn during preparation
Also, the cost of ceramic crowns is quite high, which is a significant disadvantage for many patients.
Advantages of ceramic crowns
Ceramic crowns are highly compatible with body tissues, which minimizes the risk of allergic reactions. Their use does not cause rejection or discomfort.
The absence of metal elements eliminates the risk of gum inflammation and damage to soft tissue.
Other benefits of ceramic teeth include:
- Strength They are able to withstand heavy loads, which makes them the optimal solution for restoring chewing teeth
- Oxidative stability Ceramics are not subject to oxidation, which allows you to maintain healthy gum color even with long-term use
- Aesthetics Due to their transparency and color, crowns look like natural teeth
- Lightness of design Allows you to create both individual crowns and bridges without overloading the jaw
- Perfect fit They are manufactured to precisely match the shape of the tooth, ensuring comfort and durability
- Hygiene The surface is stain and plaque resistant, making it easy to clean and maintain hygiene
Ceramic crown manufacturing process
At the initial stage, specialists carry out an examination and determine the appropriate type of crown for the patient. Next, using intraoral scanning or dental impressions, accurate measurements for future dentures are obtained. This data is used to create a plaster model in the dental laboratory.
Main stages of manufacturing ceramic dental prostheses:
- Preparation. Using casts or scans to form a plaster model
- Modeling. Creating an accurate 3D model of a tooth in a computer program
- Milling. Using the resulting model to cut out the crown frame
- Firing. Applying and firing the porcelain mass to give the crown a natural look
After the frame of the ceramic denture is made, it is processed, layers of ceramic are applied, each of which is fired sequentially. This approach ensures not only an accurate reproduction of the shape, but also an ideal combination of color with natural teeth.
Important! The choice of color is made taking into account the individual characteristics of the patient, including the color of adjacent teeth, as well as the color of skin, hair and eyes.
It is advisable to carry out the selection procedure in daylight for the most accurate match with natural shades.
