Dental prosthesis is the part of dentistry that essentially deals with replacing missing teeth. The dental prosthesis makes it possible to either reconstruct teeth decayed by caries or fractures using a dental crown, or to replace missing teeth using a fixed apparatus called “bridge” or removable ones called “metal frames” or ” satellites”.
A dental crown is a prosthesis shaped like a real tooth. A crown is placed over a tooth damaged by a decay or fracture, to cover and protect it by restoring its shape, aesthetics, size and strength. Acting like a hat, a dental crown thus artificially restores the crown of the decayed tooth. It can be a simple crown or it can be associated with an inlay-core (a false stump anchored in the root of the tooth by a tenon, which serves as anchor to the crown).A crown is either entirely made of metal alloys (metal crown) and can be covered with a cosmetic material (ceramic crown) or made entirely of porcelain (all-ceramic crown).
When it is not possible to keep an overly decayed tooth, it must be extracted.To replace it while preserving a good dental balance and an effective chewing, it is necessary to resort to the bridge technique which consists in bearing on the two neighboring teeth bordering the edentation. Dental implants are another alternative.A bridge makes it possible to replace a missing tooth, or even two, by leaning on the adjacent teeth (one on each side); beyond two, the risk of fracture is too high.A bridge of greater reach can also be realised, if it can be supported by several teeth pillars. The principle is the same as for the crown.The materials used are the same as for the crown: ceramic for the anterior teeth with the possibility of using metal for the posterior teeth.
The advantages of the dental bridge are:
The bridge is aesthetic: it harmonizes with natural teeth.
In practice, the dental bridge is part of fixed prostheses. Cleaning is therefore easier than a removable device.
Usually simply referred to as “denture”, a removable denture is a dental prosthesis which can replace several missing teeth and which, as its name indicates is mobile.A rigid metal frame is placed on the mucous membranes and the remaining teeth and is used in order to fix resin teeth – in cases where the denture is used to replace missing teeth.The denture replaces both the missing teeth and the gum.Feared by patients for its removability and size, it has the advantage of being economical and quick operation.
The ideal candidate for a dental implant is in good general and oral health. Adequate bone in your jaw is needed to support the implant, and the best candidates have healthy gum tissues that are free of periodontal disease.
Crown and Bridge FAQ
How long will my crown last?
Like many other things, the longevity of your dental crown will depend on how well you take care of it. Maintaining a regular brushing and flossing schedule will help prevent future treatment to your crown.
Are there other alternatives to a dental crown?
Yes and no. It is possible to address the area of concern with a large filling. However, it is important to note that with a large filling comes the risk of the tooth fracturing, which would lead to additional treatment. Hence, we recommend a dental crown in most cases and will only do a procedure if it is in the best interest of a patient. Our goal is to keep patients comfortable while providing the highest level of care.
Will my crown be visible?
When placing a crown, we will carefully match the color to your surrounding teeth. We want you to feel confident in your smile.
What is the difference between a crown and a bridge?
A crown is utilized to restore an existing tooth back to its natural appearance. Whereas a bridge uses surrounding teeth to help fill the gap of a missing tooth. Bridges and crowns differ from dentures, as they are fixed prosthetics. Should problems arise or additional treatment becomes necessary, a dentist will be the only one able to remove these materials.
