In the context of porcelain crowns, a substrate refers to the underlying material or structure to which the porcelain is applied. This substrate is typically made of metal, such as gold or a non-precious alloy, or it can be a ceramic material. The substrate provides strength and support for the crown, while the porcelain layer offers aesthetics and a natural appearance, mimicking the look of natural teeth. The combination ensures both durability and a pleasing visual result.

Symbol of Manufacturer: A crown marking is often used as a logo or hallmark by porcelain manufacturers to identify the origin or brand of the piece. Indicates Authenticity: It can signify that the porcelain is authentic and produced by a specific, often prestigious, maker. Historical Reference: Crown marks were commonly used by European porcelain factories, especially in countries like Germany, England, and Austria, dating back to the 18th century. Varies by Maker: Different manufacturers use different styles of crown markings (e.g., a simple crown, a crown with letters, or combined with other symbols). Used for Dating Pieces: The style and design of the crown can help collectors and experts determine the age and production period of the porcelain item. Part of Backstamp: Crown markings are usually part of a larger backstamp found on the underside of porcelain items, often alongside country names or pattern numbers.

It is most likely that the glue/cement was insufficient to keep the crown in place. You will need to return to your dentist to have it fixed.
An anatomical crown is the visible part of a natural tooth, made up by dentin covered with enamel. A dental crown is a prosthetic crown crafted by a dental technician. A dental crown can be made as a full porcelain crown, but in most cases it is made by covering a metal cap with porcelain. The metal cap is used to give the tooth extra structural strength (especially in case of molar crowns) and can be made from metal alloy, gold alloy, or zirconium oxide (a mineral).
The cost of a dental crown depends of the material of the crown (gold, porcelain fused to gold, or plain porcelain). The price is also different for conventionnal crowns or for crowns placed on implants. The price in Canada is between $900 and $1500, depending on which part of the country you live.
