The fixed prosthesis replaces natural dental elements with definitive and stable artifacts such as crowns and bridges cemented or screwed to natural support teeth or implants and therefore not removable by the patient.
The realization of these prosthetic products is made using resistant, aesthetic and highly biocompatible materials such as ceramic, zirconium or lithium disilicate.
Why is a fixed prosthesis useful?
Failure to cover a tooth can lead to its fracture compromising it up to the extreme necessity of having to extract it.
Failure to fill the edentulous areas causes the residual elements to move in the direction of the void.
The absence of teeth also causes difficulties in speech and chewing in addition to the cosmetic defect.
The advantages of fixed prostheses
- Original reproduction of the patient’s teeth, restoring function and aesthetics;
- No need to remove the prosthesis during oral hygiene;
- No discomfort or possibility of detachment, as the prosthesis is fixed;
- No food deprivation, as the chewing ability is equivalent to natural teeth;
- Biocompatibility and absolute resistance guaranteed over time
Are there any therapeutic alternatives?
The alternative to covering with a capsule for a tooth at risk can be the classic conservative composite reconstruction which in the case of very damaged teeth is not recommended because it does not guarantee strength and durability.
The alternative to bridges is given by implantology which allows to avoid irreversible compromise of elements that would otherwise be bridge pillars.
How is a fixed prosthesis applied?
For the application of the fixed prosthesis on natural teeth, the latter are reduced in size by filing them and creating pillars defined as abutments that will serve as support and on which the fixed prostheses will be cemented.
The fixed prosthesis allows the recovery of the aesthetics and functionality of the lost teeth.
There is a fixed prosthesis for your every need, choose from the following therapeutic options with the help of one of our specialist dentists.
SINGLE CROWN ON NATURAL TOOTH OR IMPLANTS
The Dental Crown (dental capsule), is a prosthesis that aims to replace the most superficial and visible part of the tooth with support given by a natural root or an implant (artificial root)
Dental crowns can be of different materials:
METAL-CERAMIC. the resistance and solidity of this type of prosthesis is given by the internal metal structure that forms what we call the “cap” which for aesthetic reasons is coated with ceramic (aesthetic material). They are indicated for the teeth of the posterior sector as these crowns are very resistant thanks to the metal of the internal structure but also for the anterior sector, as they are very aesthetic due to the ceramic that covers the external and visible part.
ZIRCONIUM . they are crowns made entirely of white-gray transition metal (zirconium) suitable for covering teeth that have lost their natural color and give dental prostheses a brighter and more natural appearance. Since zirconium is a white colored metal, it allows this type of crown to be much more aesthetic than ceramic metal since it does not present the risk of visible metal edges, while still maintaining excellent resistance.
LITHIUM DISILICATE. particularly suitable for the anterior sectors as they are metal-free crowns, and made up of all-ceramic only. The lithium disilicate crowns are highly aesthetic because they are characterized by a transparency and translucency that makes them similar to natural teeth.
BRIDGE WITH MULTIPLE TEETH ON NATURAL OR IMPLANT TEETH
This solution is adopted in cases where we need to replace one or more missing teeth using neighboring teeth as support, in fact in bridges the lost dental element is replaced by a prosthesis that includes the adjacent dental elements, reduced to abutments, prosthetic and used as pillars.
Therefore a bridge is represented by two or more single crowns between which one or more missing elements are interposed in a single fusion. The materials used vary according to the sector to be rehabilitated and the required aesthetics.
TORONTO BRIDGE, TOTAL FIXED PROSTHESIS FOR THE ENTIRE ARCH
The Toronto Bridge (Toronto prosthesis) is a fixed prosthesis screwed on 4 or 6 implants.
This type of rehabilitation allows you to carry out the immediate loading implantology technique through the use of a temporary prosthesis a few hours after the surgery.
It can be made with different materials:
Titanium structure and composite resin teeth
Zirconium structure and ceramic-coated teeth
The definitive Toronto prosthesis can also be made with composite teeth.
TOTAL FIXED PROSTHESIS ON NATURAL TEETH
In this case, the fixed prosthesis uses the teeth still present in the mouth as support pillars, which are filed and reduced to stumps in order to be then covered by the prosthesis itself.
The Maryland Bridge is an “adhesive” bridge consisting of teeth supported by a metal structure. The metal wings on each side of the bridge are “glued” with fluid resins to the existing teeth. Furthermore, natural healthy teeth are not affected. Maryland can only be used on the anterior sector and healthy teeth are not touched in any way.
