Do porcelain veneers fall off easily?

2022-07-06


Porcelain veneers are a porcelain restoration that covers part of the tooth surface. It is a cosmetic teeth restoration method. Incisors with cracks or pigments, dark yellow, black, and spots can be repaired by porcelain veneers, and the teeth turn buatiful. The main method is to stick the finished veneer to the teeth through adhesive. So, is the porcelain veneer easy to fall off? This is what we are more care about.
The main factors of the falling off of porcelain veneers (China dental lab) are as follows: 1.Improper use. Especially the use of veneers to bite hard objects, such as bones, sugar cane, melon seeds, etc. 2. Improper selection of indications. For example, if there are many defects in the tooth tissue,or the area of the tooth tissue is not enough to bond,it will discount the veneer restoration. Porcelain veneer is generally used for cosmetic restoration of discolored anterior teeth. Except for upper and lower anterior teeth, it can sometimes be used for maxillary high-end premolars. Other teeth are generally not restored with porcelain veneer ( exocad design) . Because the porcelain veneer on the upper anterior teeth is on the labial side, it does not directly bear the occlusal force, so it is widely used and the effect is better. Whether the lower anterior teeth should be repaired with porcelain veneer should be carefully selected according to the occlusal situation. If the jaw is deeply overwritten and the occlusion is too tight, the porcelain veneer of the lower anterior teeth will directly bear the occlusal force, and it is not suitable for porcelain veneer restoration. In addition, due to the abnormal occlusal relationship between the underbite and the opposite edge jaw, the veneer will bear heavy occlusal force. At this time, the upper and lower anterior teeth are not suitable for porcelain veneer restoration. Those who have the habit of grinding their teeth or clenching their teeth at night will have uncontrollable and aimless air-biting movements, which will cause damage to the veneers.(Medit I700)
