Dental porcelain is a ceramic material used in dentistry for making restorations such as crowns, bridges, inlays, and onlays.
It is composed of approximately 60% pure kaolin and 40% other additives like feldspar, quartz, and oxides to enhance its color, hardness, and durability.
The strength of dental porcelain primarily comes from its composition and the high-temperature firing process it undergoes in a dental furnace.
5 Key Factors to Consider
1. Composition and Strength
Dental porcelain is formulated to be strong and durable, primarily due to its high kaolin content and the inclusion of other minerals.
Kaolin, a type of clay, forms a stable and durable crystalline structure when heated, which contributes significantly to the strength of the porcelain.
The addition of quartz increases the hardness, while feldspar and various oxides enhance color and durability.
This combination of materials ensures that dental porcelain can withstand the compressive forces experienced in the oral cavity.
2. Processing and Enhancement of Strength
The strength of dental porcelain is further enhanced through its processing in a dental furnace.
These furnaces are designed to heat the porcelain to optimal levels of maturity, ensuring that the restorations maintain important features such as surface texture, translucency, value, hue, and chroma.
The furnace's precise control over temperature and cooling rates helps in achieving the desired strength and aesthetic properties.
The use of a tempering cooling function in these furnaces, which involves slow cooling, helps in enhancing the color effects and overall quality of the porcelain, thereby improving its strength and durability.
3. Metal Ceramic Systems
While dental ceramics are strong in compression, they generally have lower tensile strength and can fracture under low strain levels.
To overcome this, metal ceramic systems are used, which combine the aesthetic properties of ceramics with the mechanical strength of metals.
This integration provides a stronger and more durable restoration that can better withstand the functional forces in the oral cavity.
4. Controlled Firing Process
The controlled firing process in dental furnaces is crucial for enhancing the strength of dental porcelain.
This process ensures that the porcelain reaches its optimal maturity, maintaining both strength and aesthetic properties.
5. Aesthetic and Functional Properties
Dental porcelain is not only strong and durable but also aesthetically pleasing, making it a valuable material in dental restorations.
The combination of strength and beauty ensures that dental porcelain can mimic natural teeth effectively.
