METAL-FREE CROWNS (LARGE FILLINGS AND FRONT TEETH DISCOLORATION)

In our area, there has been increased number of patients with damaged front teeth and large fillings in that region. Defects on the teeth usually occur due to tooth decay, while discoloration of the teeth happens due to extracted tooth nerve or dental trauma (blow, drop ...). Therefore, frequently asked question is:

WHAT IS THE RIGHT THERAPY FOR SUCH TEETH CONDITION?

Modern dentistry cannot be practiced without teeth prosthetic restorations with METAL FREE CROWNS in the front teeth area of the upper and lower jaw.

Superior aesthetic effect can be achieved by this type of prosthetic teeth care and this method has long been present everywhere in the world as one of the most modern ways of prosthetic care. The advantage of these crowns, compared to the metal ceramic ones is that the blue discoloration of the gum in the tooth neck region is completely avoided, which originates from the metal components in metal crowns.

METAL CERAMIC CROWNS AND DENTAL BRIDGES

Lack of one or more than one tooth can be solved by creating metal ceramic crowns and dental bridges.
In some situations it is possible to restore the entire upper or lower jaw with fixed prosthetic restoration, which is the most comfortable solution for the patients, because the prosthetic work doesn’t come off i.e. it remains on the patients teeth.
This type of compensation is recommended in the lateral regions of the upper and lower jaw because of its resistance to the forces of chewing and durability.

COMPLETE DENTURES

Complete dentures are used in totally edentulous patients.
They are made of material that completely mimics the natural appearance of the teeth and soft tissues of the oral cavity.
Prostheses are kept on tissues using vacuum which ensures the safety of patient in sense that denture will not move inside the oral cavity during eating and talking.
COMPLETE IMPLANT-SUPPORTED DENTURES
Dental restoration is necessary for the proper functioning of the body, because most ailments of the digestive system are the result of the inability of chewing and swallowing due to loss of teeth.
Total dentures are manufactured in cases of fully edentulous patients in order to compensate partial loss of the resorbed bone, teeth compensation as well as to restore the chewing and swallowing function.
Dentures are kept on tissues using vacuum which ensures the safety of patient in sense that denture will not move inside the oral cavity during eating and talking. However it’s not possible to ensure their stability by means of vacuum in all cases, (especially with complete dentures in lower jaws, due to the presence of a large number of muscle tendons, the tongue and cheek muscles), which disables the consumption of all kinds of food, while dentures moving creates a sense of discomfort and lead to irritation of mucous membranes and sometimes prevent normal pronunciation which can create a number of problems in communication. For these reasons, more and more frequently, there are patients with bar-retained or ball-retained implant-supported dentures.
WHAT IS THE MINIMUM NUMBER OF IMPLANTS REQUIRED FOR DENTURE TO BE STABLE?
To create dentures fewer implants are required in relation to the production of ceramic bridge. For the lower jaw it is necessary to have minimum two implants, while in the upper jaw minimum number of implants is four.
These implants can be of various sizes and can adapt depending on the edentulous compartment with reduced bone quantity. At their ends there are ball or equator attachments and in dentures there are special dental caps; direct contact of these parts result in dentures "buttoning" to the implants.
Patients can get dentures immediately after implant placement for 3 months period, after which the bearing parts of the implant will be implemented into an existing denture and if patients have old dentures, in some cases carrying parts can be implemented in them too.

VIZIL dentures

Partial dentures also known as vizil dentures are made for the toothless patients and can rely on the remaining teeth or to be a part of fixed dentures.
Unlike acrylic partial dentures, they are stronger and more resistant to cracking and breaking due to metal structures within them.
The advantage of these dentures is that instead of the hooks, attachment systems can be installed in them and in this case these dentures can compete with fixed dentures in aesthetic sense.

UNILOCK AND INTERLOCK SYSTEMS

 

These are mini dentures carried by special attachment system that can compensate for two or more teeth depending on the situation in the patient’s mouth; they are completely reduced and far smaller than vizil dentures.
They provide comfort to the patient because they are attached to the remaining teeth in a snap-in principle (button), easy to maintain while fully meeting the aesthetic requirements.

FIBERGLASS AND CAST REBUILDING

Each endodontically treated tooth or tooth with the recovered nerve, which lacks in larger part of its crown should be strengthened with fiberglass or metal post. After endodontic treatment the tooth is not getting sufficient nutrition as a healthy tooth would i.e. tooth with healthy nerve, so it becomes more brittle and breakable.
To prevent tooth cracking, fiberglass post should be incorporated or cores rebuild by removing two-thirds of the root canal’s hard layer, then by setting the post in a certain position and cementing it. Then the excess of the post will be removed but enough left to be modeled in tooth grinding shape.
Once the cement hardens the remaining coronal defect can be replaced, depending on the size of the defect, conservatively with fillings or with ceramic or metal-ceramic crown prosthetic solution.
Unlike fiberglass, cast rebuilding is made in two stages and in this case coronal defect cannot be compensated with composite filling but only with prosthetic solution.

CERAMIC INLAYS

What this method differs from ordinary tooth filling is taking an impression of the tooth prepared cavity, moulding of the plaster working model and development of the adequate compensation in dental laboratory - inlay which is then cemented in the mouth.

CERAMIC FACETS - VENEERS

Ceramic veneers are fine flakes of zirconium, lithium disilicate ceramics, e-max pressed ceramics built mainly on the front teeth as an aesthetic restoration. For this kind of restoration tooth is ground minimum (0.3-0.5 mm) from the outer side and veneers are permanently cemented to the tooth.
They are used for teeth correction of color and shape and rarely in fixing the teeth position irregularities.
