Champion Dental Clinic
When it comes to dental restoration with crowns, many customers nowadays prioritize choosing all-ceramic crowns due to their outstanding advantages. This type of restoration offers excellent functional restoration and high aesthetic appeal. However, in certain cases, customers may opt for metal ceramic crowns to restore one or two individual teeth. In this article, Champion will help you better understand the differences between metal ceramic crowns and all-ceramic crowns.
What are Metal Ceramic Crowns?
Metal ceramic crowns are among the most advanced types of ceramic restorations used in aesthetic dentistry, and this information is well-known among many customers. The standout feature of metal ceramic crowns lies in the creation of a sturdy framework made from durable alloys such as nickel-chrome, nickel-cobalt, titanium, or precious metals. The outer layer is then coated with colored ceramic, providing a remarkable aesthetic outcome for the teeth.
What are All-Ceramic Crowns?
All-ceramic crowns are one of the modern types of ceramics crafted using advanced 3D CAD/CAM technology, ensuring absolute precision in every small detail, including size, shape, color, and even tooth grooves. As the name suggests, all-ceramic crowns are made entirely from pure ceramic without any metal additives. This provides a high level of biocompatibility and ensures safety for the oral environment. Every component, from the framework to the porcelain layer, is crafted using pure ceramic material, ensuring purity and superior quality.
The Differences Between All-Ceramic Crowns and Metal Ceramic Crowns
Aesthetic Appeal
Aesthetic appeal always ranks at the top of the list of important criteria that customers consider when opting for ceramic crowns, as it directly impacts their personal appearance. Based on this aspect, all-ceramic crowns clearly excel.
Due to the metal framework, metal ceramic crowns can affect the color of the teeth and make them less optimally white. In particular, when exposed to light, the teeth may appear to have some dark lines. Therefore, metal ceramic crowns are not the ideal choice for front teeth or full-mouth restorations.
All-ceramic crowns, on the other hand, are the highest in aesthetic appeal, with a variety of color tones and vividness, resembling natural teeth. Even under light exposure, the color of the teeth remains unaffected, keeping them bright and evenly toned. With superior aesthetic qualities, all-ceramic crowns can be suitable for various positions in the mouth.
Durability of the Crowns
Customers always care about the load-bearing capacity and durability of the ceramic crowns to ensure stability in chewing function.
Metal ceramic crowns have good load-bearing capacity due to the sturdy metal framework inside. However, over time, the crowns can wear down, leading to a significant decrease in chewing ability.
All-ceramic crowns, on the other hand, are made from layers of ceramic that have undergone high-temperature firing (>1400 degrees Celsius), providing superior load-bearing and heat resistance. This allows customers to comfortably eat and drink without restrictions, and they won't experience sensitivity or discomfort when in contact with hot or cold food.
Risk of Gum Margins Turning Dark
The risk of gum margins turning dark is one of the important differences between metal ceramic crowns and all-ceramic crowns.
In the case of metal ceramic crowns, the porcelain gum margins may gradually darken due to the oxidation of the metal components when exposed to the acidic environment in the oral cavity. This phenomenon not only affects the overall aesthetics of the smile but also detracts from the esthetic appearance.
With all-ceramic crowns, customers can be completely assured because the occurrence of dark gum margins is unlikely. The crowns will remain bright and shiny as they were initially.
Durability of Crowns
The average lifespan of metal ceramic crowns ranges from 5 to 7 years. After this time, there is a risk of crown debonding and gum margin discoloration. Therefore, customers should consider replacing the crowns to ensure oral health is not compromised.
On the other hand, all-ceramic crowns can have a lifespan of 15 to 20 years, or even longer. Particularly, they do not encounter issues like discoloration, gum recession, or bad breath.
When to Choose Metal Ceramic or All-Ceramic Crowns?
When choosing the appropriate type of crowns, important factors for the dentist to consider are the patient's oral condition, the extent of tooth damage, their needs, and financial ability.
If the patient does not have sufficient finances for full ceramic crowns, the dentist may propose using metal ceramic crowns for one or two teeth in the posterior region. Although they may not meet high aesthetic standards, they can still fulfill functional requirements.
With the financial means, opting for all-ceramic crowns will provide confidence in a healthy and durable smile over the long term. Additionally, for individuals with metal allergies, all-ceramic crowns are the best choice for restorations.
To receive the most accurate advice on choosing between metal ceramic and all-ceramic crowns, it is recommended to consult a reputable dental clinic.
