The difference between ceramic teeth and porcelain teeth

There are still differences between ceramic teeth and porcelain teeth. First of all, they are different in appearance and material. Generally, it is better to pay attention to the symptoms, because it is not a matter of pressing two kinds of teeth and choosing which one is better, but it depends on which kind of teeth is suitable for your situation. Because when implanting teeth, it is not the quality of the teeth that matters, but the overall conformity of the teeth.

Advantages of ceramic teeth 1. Good edge sealing

2. Beautiful

3. Good biocompatibility

4Extremely high strength

5 Protecting the hard tissue and pulp of the tooth Classification of porcelain teeth [1] Porcelain teeth are generally classified according to the metal used in the inner layer. Generally divided into two categories:

Porcelain teeth are suitable for 1. Teeth that need to be repaired after root canal treatment due to pulp, periapical lesions or hidden cracks;

2. Discolored teeth, such as dead teeth, tetracycline teeth and fluorosis teeth, which are not suitable for restoration by other methods;

3. Teeth with deformed small teeth, enamel hypoplasia, etc. that need to improve the crown shape;

4. Patients whose front teeth are misaligned or twisted and are not suitable or cannot be treated with orthodontics but need to improve the aesthetics of their front teeth;

5. Repair of single tooth defects and retainers of fixed dentures;

6. Fixed splints for orthodontic treatment of periodontal disease.

Classification of types: Porcelain teeth are composed of two layers: an inner metal base layer and an outer porcelain layer. According to the different materials of the metal base crown, they are divided into three categories: precious metal alloy porcelain crowns (represented by gold alloy porcelain crowns), non-precious metal alloy porcelain crowns (represented by nickel-chromium alloy porcelain crowns and cobalt-chromium alloy porcelain crowns), and titanium alloy porcelain crowns.

1. Precious metal alloy porcelain crown: Porcelain crowns made of precious metals are called precious metal porcelain crowns. Precious metals have good chemical inertness, making them resistant to oxidation and corrosion. The most commonly used precious metals in dentistry include: gold, platinum, palladium, etc.

2. Non-precious metal alloy porcelain crown: Porcelain crowns made of non-precious metals as metal base crowns are called non-precious metal porcelain crowns. Non-precious metals are easily oxidized at high temperatures and have relatively weak corrosion resistance, especially in a humid oral environment. Metal ions are easily precipitated, which may cause gray discoloration of the gums. Some metals are also allergenic. The most commonly used non-precious metals in dentistry include: nickel, chromium, cobalt, aluminum, etc.

3. Titanium alloy porcelain crown: Titanium should belong to the category of non-precious metals, but because it has many different properties, it is listed separately. Titanium has the advantages of good biocompatibility, corrosion resistance, and low thermal conductivity. However, due to its high melting point, difficult casting process, easy oxidation, relatively poor bonding between the metal base and the porcelain layer, easy collapse of the porcelain layer, and the need to use special porcelain powder processing, its wide application is limited.
