Dental restoration consists in restoring the chewing function of a missing or decayed tooth structure, reinforcing a damaged or worn tooth or improving the aesthetic aspect of a tooth.
There are various types of materials used (amalgam, composite resins, porcelain, ceramics, zirconium…) and dental restoration techniques performed.
Depending on the position of the tooth and the type of dental disease to be treated, the dentist will suggest a personalized solution adapted to each specific clinical situation. Dental restorations may also correct a crack, fill/repair a chipped tooth, or correct a minor malposition or discolouration…
Materials are constantly evolving in dentistry. A dentist can nowadays offer a variety of therapeutic options.
Here are the most common techniques used in dental surgery
Everything about dental care:
Often called amalgam filling, amalgam is a material that has been used for more than 150 years in dentistry. Contrary to popular belief, this type of filling does not contain any lead, as it is an alloy made of mercury, copper, zinc, tin… The presence of mercury gives rise to certain critics because of the toxic nature of mercury. But, according to the Ordre des dentistes du Québec (the Québec dental association), there is no proven reliable data showing that dental amalgams have any effects on health.
The amalgam is a very resistant material, relatively cheap and easy to apply. It is widely used in child dentistry to treat a cavity on a primary tooth.
On the flip side, amalgam restorations are not very aesthetic. They are visible and they are steel-gray in colour.
Unlike the amalgam, composite resins are relatively recent materials. Their formula is regularly improved. There are thus several generations of composite resins.
Composed of polymers and of biologically inert very hard particles, composite resins are glued to the tooth by means of an adhesive resin. White in colour and having an aesthetic appearance, the composite resin is a material used in dental restoration and in correcting defects resulting from tooth decay, from a fracture, or from a malposition of a tooth.
A fluid version of the composite is used as a sealant in fissures to prevent the development of cavities.
The composite offers a lot of flexibility, comfort, and stability. It is widely used in general dentistry.
Fixed prostheses, inlays and onlays or ceramic crowns are aesthetic and durable. The dentist first prepares the tooth to be treated, takes an imprint, and then asks his dental technician to fabricate a fitted custom-made ceramic tooth.
They are made of porcelain or composite. Veneers are thin shells that are glued to the surface of the tooth. Dental veneers are aesthetic and resistant to food stains.
- Porcelain veneer
First, the dentist prepares the visible surface of the tooth, and he then takes an imprint. Once the veneer is fabricated by the dental laboratory, this veneer is bonded with resin cement.
- Composite veneer
Unlike the porcelain veneer, the composite veneer is a resin that is applied directly onto the tooth with a resin adhesive and a curing lamp. The dentist adjusts the veneer and polishes the surface.
Typically fabricated in a laboratory, gold inlays are restorations that replace amalgam or composite resin fillings. They offer exceptional durability and do not oxidize over the years. Gold inlays (made from a noble metal) protect the tooth against the risk of fracture and allow for better chewing of food.
