Dental prosthesis is that branch of dentistry that creates an artificial substitute for natural teeth.
In cases of edentulous, or partial or total lack of teeth or to correct aesthetic defects in the shape, position and color of the teeth, or, in some cases, to rehabilitate dysfunctional occlusion.
It is distinguished by type:
Fixed prosthesis: formed by bridges or crowns that are cemented to the teeth, they are not removable by the patient.
Removable or mobile prosthesis: it is the dental prosthesis that the patient can, and must, remove from the mouth for cleaning.
Combined prosthesis: it is composed partly of fixed prostheses and partly of removable prostheses, closely connected to each other.
There are various types of fixed dental prostheses:
Fixed prosthesis in metal-ceramic: it is made up of a noble alloy (i.e. with a more or less high percentage of gold) and ceramic.
Fixed all-ceramic prosthesis: these are bridges or crowns made of all-ceramic, without metal parts.
Prosthetics on implants: dental prosthesis built on dental implants (implants are like artificial tooth roots).
There are various types of removable or mobile dental prostheses:
Partial prosthesis in removable or mobile resin: dental prosthesis replacing some dental elements, with mucous support, equipped with hooks applied to the residual teeth. This type of prosthesis has gums and teeth made of a particular resin. Today it is mainly used as a provisional, pending the application of more efficient artificial substitutes.
Total prosthesis in removable or mobile resin: dental prosthesis replacing all the dental elements of an arch, with mucosal support and sealed with a subsidization mechanism or through implants.
Removable skeletonized (skeletonized) prosthesis: replacement prosthesis of natural teeth, which can be removed by the patient. The skeletonized prosthesis (skeletonized) is a dental prosthesis with mixed support, dental and mucous, whose seal is guaranteed by hooks applied to the residual teeth.
It’s composed by:
– metal structure, generally a cobalt-chromium alloy, constituting the load-bearing skeleton.
– resin saddles that reproduce the appearance of the gum, which rest on the gingival mucosa and support the teeth, also in resin.
– replacement teeth.There are also ceramic (porcelain) veneers in case of fractures, anomalies in shape and size, position defects (for example an excessive space between the teeth) or discolouration. ceramic layer bonded to the external face or visible surface of the tooth. To apply them you have to prepare by filing the tooth minimally. The quality of the product obviously makes the difference both in aesthetics and in their duration.
In our dental centers we use the latest digital technologies for diagnosis with low-dose CT, for impressions no longer with paste materials but with the intra-oral scanner. Read more about the paste-free impression
We use materials such as zirconium (white, bio-compatible and very hard) and all-ceramic for aesthetic results of absolute naturalness and durability.
