Fixed Prosthodontics

Fixed prosthodontics offers many solutions for tooth protection, missing teeth replenishment, or erosion and damage restoration. Crowns, bridges, inlays, onlays, and overlays are restorations that are firmly placed and cannot be removed by the patient. Those are constructed by dental technicians, as removable prostheses are; and to always ensure the best quality, we collaborate with advanced laboratories in Cyprus as well as abroad. Each of these laboratories is specialized in specific restorations and uses modern 
technologies.

crowns

crowns

Crowns are fixed prosthetic restorations that are used to cover a tooth and restore its shape,
size, strength, functionality, and aesthetic appearance.

Crowns are necessary in the following cases:

  • When a tooth is subjected to endodontic therapy, and we may need to remove the better part of the dental tissue. This way the tooth becomes more fragile, and we place the crown for its protection. The same happens in fillings, when we face extensive damage and tissue loss.
  • When we have a broken tooth by any cause, a filling is not sufficient for its protection, so we cover it by crown. If a tooth has cracks, a crown prevents the crack expansion that usually results in fracture.
  • When we have big, old fillings; the tooth is gradually thinning and becomes vulnerable. With the crown we prevent further erosion.

Crowns are constructed in the laboratory by various materials, the ones though that
aesthetically prevail are all-ceramic and zirconia crowns.

Bridges

Bridges are fixed prosthetic restorations and are recommended when a patient has lost one or more teeth. The bridge function is important, as it contributes to the maintenance of our total oromandibular health and balance, while it can prevent more serious future problems.

When one or more teeth are missing, the adjacent teeth start to move toward the gap and to cause malocclusion, i.e. abnormalities in the upper and lower teeth relation during chewing. The occlusal forces are not evenly distributed, and thus the remaining teeth receive stronger
pressures, which may cause erosion. The loss of one or few teeth may gradually lead to the loss of more.

To cover the gap or gaps, we use bridges. Bridges consist of two crowns, which are adjusted onto our natural teeth to the right and left side of the gap, after these teeth have been perimetrically ground down; and the artificial teeth are adhered at the middle of the structure. The adjacent natural teeth are therefore act as supports for the bridges.

For the bridge construction we take the patient’s exact teeth impressions that will guide the dental technician to prepare the restoration specifically for you. The construction material
usually is porcelain or zirconium, which gives better aesthetic results.

Bridges have long lifespan, as long as the patient complies with the oral hygiene rules. If the
natural teeth-supports develop periodontal problems, problems for the bridges will also occur.

Bridges are a good solution, but we have to remove healthy tissue from the natural teeth, and also they cannot prevent the resorption of the bone after tooth loss. A better option is, of course, implants.

Inlays - Onlays
Overlays

They are minimally invasive fillings that are constructed outside of the mouth and then adhered to the posterior teeth. We use them as a restoration after caries removal or in case of a fracture. They cover a greater extent of a tooth compared to common fillings, and can restore even the entire occlusal surface.

The inlays, onlays, overlays can mimic the mechanics and structure of a natural tooth, and thereby can restore the strength, functionality and aesthetic of a damaged tooth. This is the
so-called biomimetic approach that considers that a restoration must be minimally invasive and compatible with the mechanics of the natural tooth, in order to prevent future erosion and
additional dental works.

Inlay Onlays Overlays

Inlay Onlays Overlays

The material used for their construction may be micro ceramic resin or porcelain, and their
use is indicated in many cases when we want to avoid further tooth ground down, which is the case in crown placement. Inlays were always used in dentistry and were usually made of
gold. In recent years, due to the development of materials, we are able to construct inlays of
great strength and aesthetics with porcelain.

The advantages of onlays are:

  • Comparatively less time on the dental chair, since for a proper conventional filling sectional resin layering and plenty of time are required.
  • The polymerization of the material occurs outside the mouth, and as a result the contraction takes place before the bonding. This way we minimize the microgaps that may occur during contraction. Instead, in common fillings, polymerization occurs inside the mouth, and this may cause bigger gaps at the filling borders, resulting in penetration of food between the gaps.

For the inlay, onlay, overlay placement, minimum tooth ground down is required, and it is
possible in the future, if need be, to further ground down the tooth for crown placement. On
the contrary, if a tooth that has been ground down for crown placement degenerates, it would
have to be extracted. With these dental restorations, we are, therefore, able to extend the
tooth’s abidance inside the mouth.

CAD/CAM Technology

With the modern computed CAD/CAM technology (Computer-aided Design and Manufacturing), we can construct prosthetic and aesthetic restorations, such as crowns, inlays – onlays, and porcelain veneers.

The technician can design the restorations on a computer, using a specific software that
processes various data and three-dimensional representations of the oral cavity. When the
design is completed, the data are sent at special machine. This device three-dimensionally forms a piece of composite or porcelain into the appropriate shape and size to fit perfectly in the mouth of each patient. CAD/CAM offers absolute precision in the design of the prosthetic restoration, significantly reduces the construction time, and does not require conventional
impressions.
