How long Can Porcelain Teeth be Used?
Porcelain teeth are very powerful in dental restorations. Many dental problems can be solved by this method, so they are widely used in clinical practice. However, porcelain teeth also have a certain useful life. So how long can porcelain teeth generally be used, and how can it prolong the life of porcelain teeth?
- The quality and design of porcelain teeth
If the design of porcelain teeth is unreasonable, it may cause denture fracture or loosening of real teeth due to excessive force, which will affect the normal use of porcelain teeth. The ceramics constituting the external shape of the porcelain teeth, while providing good aesthetic effects, cannot avoid its own shortcomings, that is, the problem of greater brittleness. Therefore, improperly designed and manufactured crowns subjected to large occlusal pressure can cause ceramics to crack or even crack, or the ceramics to peel off from the metal surface.
- Biological stability factors of the materials used
In China, most people use metal porcelain teeth. The metal inner layer structure of metal porcelain teeth not only provides reliable strength, but also comes into close contact with the soft and hard tissues of the oral cavity. The performance of these teeth directly affects the physiological health of the oral cavity. It is biologically stable, and the precise inner metal structure of porcelain teeth can be made to “coexist peacefully” with the soft and hard tissues of the oral cavity, coordinate with the overall oral environment, and become a part of the oral environment of the patient.
In contrast, alloy materials with poor biological stability and poor biocompatibility will cause adverse irritation to surrounding tissues, and are prone to corrosion, unstable metal ion exudation, and tissue allergies, which will cause gingivitis, periodontitis, and gingival margin. Black lines (mainly nickel-chromium porcelain teeth), if the crown and teeth are not close, it may even lead to adverse reactions such as caries.
- Edge sealing of porcelain teeth
Porcelain teeth are fixed on the abraded tooth with an adhesive. The gap between porcelain teeth and real teeth is sealed by cement. Therefore, the closer the crown and the teeth are, the more the gap between the two. The smaller it is, the better it is to preserve natural teeth. Otherwise, the larger the gap between the two, or the low quality of the cement, will cause pathogens to enter the gap and cause corrosion of natural teeth, which will affect the service life of the porcelain crown. The better the process of making porcelain teeth, the better the edge sealing performance is. Porcelain teeth with poor manufacturing process have poor precision, poor adhesion and large gaps.
- Patients using porcelain teeth themselves
If you have to use your porcelain teeth to bite hard objects, or do not pay attention to oral hygiene, then your own real teeth will be damaged, let alone porcelain teeth? So the service life of your porcelain teeth is largely related to your use.
- Porcelain dental care is the key
First of all, in terms of diet, it is best not to eat hard food, because it takes a certain time to adapt after the porcelain teeth are repaired. If you do not bite the hard food before adapting, it is likely to stimulate the porcelain teeth to compress the gums and other tissues. Inflammation such as gingivitis; try not to eat irritating foods, because the metal inner crown of porcelain teeth has some chemical properties that are unstable, and may easily react with some irritating foods in life, such as overacid foods. Some ions in the metal substance may be in a free state, which may easily stimulate the gums and other parts, which may cause some allergic phenomena to the human body.
Secondly, in terms of cleaning, after making porcelain teeth, patients should pay more attention to the cleanliness of porcelain teeth and develop good oral hygiene habits. In this way, the service life of porcelain teeth can also be maximized.
[What are the factors related to the life of porcelain teeth]
Many people think that porcelain teeth are permanent. In fact, porcelain teeth have a certain life span. The life of porcelain teeth is related to many factors. So, what factors will affect the life of porcelain teeth?
- Doctor’s skills and mentality
Many friends often ignore this point and focus on the size, grade, quality of equipment and materials used for porcelain teeth in hospitals or clinics. They often only care about making porcelain teeth that contain no nickel. Technical considerations are less common. The doctor’s technology always comes first. Only highly skilled doctors can make high-quality porcelain teeth. If the doctor pays too much attention to the immediate economic benefits, he does not consider the actual needs and economic conditions of the patient, and designs porcelain teeth that do not meet the actual situation of the patient, or even exceed the indications for porcelain teeth. Tooth life will not be long.
- Materials for porcelain teeth
Good materials have good physical and chemical properties and stability, which we call biocompatible. The metal in the inner layer of porcelain teeth is in close contact with the soft and hard tissues of the oral cavity, and its performance directly affects the physiological health of the oral cavity. The dental crown with good biocompatibility can get along with the soft and hard tissues of the oral cavity and coordinate with the human body. Dental crowns with poor biocompatibility will cause bad irritation to surrounding tissues, allergies, corrosion, metal ion exudation, etc., which may cause gingivitis, periodontitis, black lines around the gingival margin, and oral odor, which will affect porcelain Tooth life.
- Daily care of porcelain teeth
Patients’ careful maintenance of porcelain teeth can prolong the life of porcelain teeth. Eating cake with porcelain teeth every day is definitely different from eating pecans every day. So when you wear porcelain teeth, you should pay more attention to it. It is better not to eat hard food often. Pay attention to maintaining oral hygiene, brush your teeth carefully, and regularly visit the hospital to clean your teeth. If you use porcelain teeth to bite hard objects, or do not pay attention to oral hygiene, then porcelain teeth will die prematurely.
