The main problem of removable onlays – they provoke the development of caries. Using universal plates, it is impossible to ensure a tight fit to the gum. Bits of food get stuck under the edges, providing bacteria with a breeding ground. It is difficult to notice decay, because it is masked by the onlay. The tooth can rot away completely while attention is paid to it.
Advertising claims:
- If you buy veneers from a drugstore, you can avoid spending money on expensive preparatory procedures.
But such procedures are necessary for dental problems. Plaque needs to be removed, decay needs to be treated, otherwise you can quickly be left without teeth. - Removable onlays mask missing teethThat’s right, you can’t see the hole. There’s another problem. When there are missing teeth, the neighbors lean toward the void, and the antagonist tooth (the one opposite) goes down on the upper jaw, and up on the lower jaw. Thus the bite is disturbed. This leads to problems with the upper jaw joint and makes dentures very difficult.
- The criterionisthat they do not fall out when speaking. First, the statement is true only for quality onlays made according to the results of the scan. Secondly, the fact that the design does not fall out, does not give any guarantee of tight fixation, because you can easily slip a fingernail between the gum and the onlay. If a fingernail gets in there, there will be no barrier at all for bacteria. But for saliva to clean the oral cavity naturally, it will serve as an obstacle.
- Theproducts are safe to useHere, too, it all depends on the manufacturer. Snap-on Smile, TruSmile, and Ruveneers are made of medical grade plastic. Although it can sometimes cause allergies, but there is no data on the toxicity of such products. But the designs bought on the Chinese market, without specifying the manufacturer and composition, can lead to poisoning and allergic reactions. The fact that they do not stick in the mouth is for the good – less harm.
- Experts confirm the positive effectDuring the entire time (about 20 years) of using removable veneers, 11 articles have been published. For comparison, publications about ceramic veneers number in the hundreds. And there are not general phrases, but concrete figures. They confirm that after 20 years, 91% of patients still use their veneers. In a review of the few publications on prefabricated veneers, it is stated that they:
- Look unnatural
- Increase the risk of tooth decay and plaque development
- Short-lived Among the pros, the review notes the relatively low cost, the absence of grinding and the possibility to abandon the onlays.
It should be emphasized that the publications are talking about removable veneers made on the basis of a scan of the teeth, that is, individual onlays. About universal plates, no scientific works have been published.
Removable veneers, reviews of which are published not on the website of manufacturers, but on publics, gain no more than 1 star. Independent opinion of people who have purchased such products leaves no doubt that the savings are only apparent, the quality of such products can not be compared with ceramic restorations.
