Dental veneer, as a tooth beauty technique, is increasingly popular because of its perfect effect.
Veneer is a technique for tooth whitening repair. Tooth whitening repair is to paste a layer of material with a normal tooth color on the surface of discolored or defective teeth for whitening or repair. This technology has been widely used in stomatology and is popular with consumers.
The veneer,also known as the tooth veneer, is a bonding technique used to directly or indirectly adhere to the restoration material on the surface defects of the teeth, stained teeth, discolored teeth and deformed teeth, etc., while preserving the living marrow, less or no molars. Knot covering, a restoration method to restore the normal shape of the tooth body and improve its color.
- Direct veneer restoration
Direct curing, curing and polishing in the mouth of the light-curing composite resin to complete the restoration of the tooth body. Its advantages are simple, flexible and completed in one time, but due to the influence of many factors in the mouth, the edge shape and surface texture of the veneer are difficult to meet the ideal requirements; the conversion rate of the monomer in the directly cured resin in the mouth is generally low, which seriously affects the veneer Quality; in addition, the long operation time beside the chair also limits its clinical application.
- Resin veneer
The biggest advantage of using resin directly in the patient’s mouth is convenience, speed and speed. Can quickly improve the patient’s front teeth. For anterior teeth fluorosis teeth, mild tetracycline teeth, undersized teeth, interdental teeth gaps, partial defects of traumatic teeth, etc., if the patient cannot accept the cost of porcelain veneers and super porcelain veneers in the short term, it may be a short-term transition to improve aesthetics. Restoration.
- Indirect veneer restoration
It is mainly made of ceramics or hard composite resin materials on the model. The production of indirect veneers is not limited by the operation time of the chair, so it can be fully modified, modified and polished outside the mouth. The repair effect is often better than that of direct veneers.
- Porcelain veneer
Porcelain veneer is a kind of repair method that uses adhesive materials to fix the thin artificial ceramic restoration on the lip surface of the affected tooth to cover the defects such as discoloration and discoloration that affect the appearance. As a conservative restoration treatment method, it has been widely used in clinic in recent years, and is particularly suitable for the cosmetic restoration of young permanent teeth and anterior teeth with large pulp cavity. Porcelain veneer has the advantages of beautiful color, less tooth preparation, anti-liquid absorption, good biocompatibility, anti-abrasion, periodontal health care and firm and reliable bonding. Porcelain veneer can be divided into three categories according to different production methods and materials: traditional porcelain veneer, cast porcelain veneer and CAD/CAM machined porcelain veneer.Currently there is multi layer dental zirconia veneer is available now,The multi layer zirconia dental venner restoration features 700Mpa strength,49% translucency in most aesthetic nature impression on others!
This technology is also called hard resin veneer, super porcelain veneer, and porcelain-like veneer. The material of teeth whitening veneer is to add a large amount of porcelain powder particles to the resin, which not only improves the wear resistance of the resin, but also greatly improves the aesthetic performance of the resin. Its clinical operation process is similar to porcelain veneer.
Tooth paste has excellent aesthetic effects on dental problems such as dental fluorosis, mild-to-moderate tetracycline teeth, and slight misalignment of teeth, and has minimal damage to patients’ teeth. Therefore, more and more people choose the form of veneer to repair teeth .
Less abrasive tissue. Porcelain veneer wears less tooth tissue. In some cases, it is not even necessary to remove tooth tissue. This can save a large amount of tooth tissue without the need to kill nerves. It basically controls the repair of postoperative dental pulp inflammation and necrosis. Sequelae can maintain the long-term health of natural teeth.
The simulation effect is good. The cosmetic effect simulated by porcelain veneer has the same optical characteristics as natural tooth tissues, does not contain any metal components, and exhibits the best aesthetic effect. There will be no gingival black lines common to porcelain teeth. When making porcelain veneer, there are many different colors of ceramic blocks to choose from, and at the same time, external dyeing can be used for fine color adjustment. In clinical bonding, there are a variety of different shades of adhesive and white masking agent that can be used to assist in adjusting the color of the porcelain veneer to achieve an overall coordinated cosmetic effect. And the high wear resistance and non-coloring of the porcelain itself can make the porcelain veneer achieve a permanent whitening effect.
Little irritation to gums. The porcelain veneer has excellent light transmittance, and the gums can be leveled when the teeth are prepared, which is beneficial for protecting the gums and making impressions and bonding porcelain. The area that is in contact with the gums is also only on the lip side, which is less irritating to the gums. There will be no discoloration of the gums caused by the metal ions of metal porcelain teeth. The hardness of the porcelain crown is greater than the enamel, which can cause abrasion of the jaw teeth. The hardness of porcelain veneer is slightly lower than that of tooth enamel, which can effectively protect the jaw teeth.
No oral foreign body sensation. The restoration of traditional porcelain teeth requires grinding of the natural teeth on the tongue side, and the teeth on the tongue side are usually healthy, and are in the most harmonious state with the tongue and the teeth. Even the best metal porcelain teeth cannot be restored to the state of natural teeth. Porcelain veneer restoration basically does not need to sharpen the lingual part of the tooth, and can save most or all of the lingual form, effectively protecting the jaw teeth, and the tongue is still exposed to the natural teeth that are not damaged, and the touch is natural , Comfortable, to avoid the “foreign feeling” when the tongue comes into contact with traditional porcelain teeth. Therefore, porcelain veneer has good comfort.
Adapt to the main people
Currently popular dental veneers can be divided into resin veneers and dental zirconia veneers, which is currently the most popular way of tooth beauty. But it is not to say that tooth veneer whitening is suitable for all types of teeth, and its adaptation population includes:
- Abnormally shaped teeth, dysplasia of enamel, too small teeth, etc.
- Moderate and severe tetracycline teeth, fluorosis teeth, etc.
- Caries caused by caries erosion at the cut end or shallow tooth surface.
- The teeth are sparse or the teeth are slightly distorted, and do not want to be corrected but the teeth are normal.
- Drug-induced discoloration of teeth.
- Hereditary yellow teeth.
- Serious cases of tooth cracks, incompleteness, or potholes.
See a doctor
Patients who make dental veneers should be more cautious. According to their personal situation, “medicate the symptoms” and go to a regular hospital for treatment to ensure the good results of the restoration.
- Check and judge.
Detailed oral examination, select the appropriate indication, communicate with patients, doctors, and technicians to formulate a suitable treatment plan.
- Basic treatment:Make up the teeth, professional tooth cleaning, eliminate gum inflammation.
- Tooth preparation.
According to the specific conditions of the patient’s teeth, prepare the adapted tooth body.
- Impression, model, color comparison.
Take the impression with silicone rubber or elastic impression material, and directly pour the working model with the high-temperature resistant molding material, or pour the working model with super-hard gypsum, and then use the working model to replicate the high-temperature resistant molding. When comparing colors, consider the shade of the patient’s teeth. The color after restoration cannot be too different from the color of the remaining real teeth, otherwise it will affect the appearance.
- Temporary restoration.
Make and try it on, bond with adhesive, adjust and trim.
Second visit of dentist
- Tooth veneer bonding.
Try it on, use special adhesives and bonding methods to remove excess material and keep the edges smooth.
- Adjust the bite relationship.
Because the veneer is very thin and the brittleness of porcelain is large, if the veneer directly bears the bite force, it is easy to crack the veneer, so the tooth veneer should not exceed the cutting edge of the real tooth when doing the veneer tooth veneer restoration And, when the lower anterior teeth are extended, they must not be in contact with the cutting edge of the veneer.
Many people choose tooth veneer whitening, thinking that it will be “once and forever”, but from a professional point of view, the whitening effect of veneer still needs to be maintained by the patient’s careful care. The better the veneer care, the longer it will be used. The following tips may be helpful:
- Matters needing attention.
After the veneer is repaired, do not eat food that is too cold or too hot for a short period of time. Because the tooth surface is etched before the veneer is bonded, this may cause allergic symptoms of the tooth. Hot and cold stimulation may aggravate the symptom, and even stimulate the pulp to evolve into pulpitis.
- Care when brushing teeth.
(1) It is recommended to use a soft-bristled toothbrush, please do not brush your teeth too hard.
(2) Please avoid using coarse-grained toothpaste. The particles in the toothpaste will affect the finish of the veneer.
(3) Please pay attention to the position of cleaning gums.

(2) Start practicing flossing at one location, and then carefully use flossing at each location.
- About diet
(1) Try to avoid eating red wine, tea, coffee, and plum foods because they can cause pigmentation on the veneers of the teeth.
(2) When eating hard food, be extra careful not to damage the veneers.
The dental veneer is made of all-ceramic material, the thinnest can reach 0.2mm
- Stay away from tobacco.
(1) It is recommended to quit smoking immediately.
(2) Avoid chewing tobacco, any tobacco will cause pigmentation of the tooth veneer.
