Prosthetics
Prosthetics involves both supplementation of missing tooth tissues and a missing tooth of teeth. The loss of even a single tooth has some affect on the masticatory function, to say nothing of aesthetic considerations. Such a loss should be supplemented as soon as possible, as the teeth provide such a consistent system that failure to do so may lead to migration and rotation of teeth adjacent to the missing one, "elongation" of the corresponding opposite tooth and bone atrophy. All the phenomena may lead to the loss of subsequent teeth and temporomandibular joint disorders.
There are numerous kinds of inlays, used to fill cavities. Cast metal inlays have been used in dentistry for 100 years. First a tooth is appropriately prepared and then a wax impression of a gypsum inlay is made. Finally a metal composite resin or ceramic inlay is cast. A hardened inlay in its final form is cemented in a cavity or glued with a special adhesive material. Using inlays enables reconstructing the chewing surface of a tooth, thanks to which the tooth is actively and fully used in chewing food; moreover, it is possible to restore contact points and maintain appropriate tooth and mouth care.
ONLAYS
In order to fill huge cavities, also in lateral teeth treated previously with a root canal therapy (not to be treated with implant-borne prosthetic crown yet) the so-called onlays are used, which cover the whole chewing surface of a tooth. Composite resin structures are modelled in a lab, where the high-temperature polymerisation process is carried out using a special machine. An onlay is cemented to the dental tissues with adhesive resins, which results in a complete filling a dental cavity at the dentist's office.
Inlays and onlays are made of composite resin, porcelain or gold, the porcelain ones being the most modern solution. The indirect method, used to model onlays in a lab, enables achieving almost ideal reconstruction on the anatomical profile of a tooth and its contact point. Even better results are obtained when cast porcelain or pressed porcelain is used. Onlays and inlays made of gold are as efficient a solution as porcelain ones. Gold is an ideal material for dental reconstructions, as gold object help to prevent secondary caries due to bacteriostatic properties of the metal, the only disadvantage being aesthetic factors: gold inlays or onlays are visible because of different colour.
These are removable restoration made of acrylic plastic. The main indication for their use involves toothlessness or extensive tooth loss, where the application of other dentures (skeletan, permanent, implant-based ones) is impossible.
Overdenture is a removable prosthetic restoration that covers the whole surface of the roots of remaining teeth, or implants. Such dentures are fixed on the roots or implants by a system of locks (usually ball ones). This type of restoration fulfils aesthetic needs, protects the jaw bone from atrophy and provides the patient with acceptable comfort. However, a prerequisite for the use of such dentures is for the patient to acquire principles of perfect oral hygiene and regular check-up visits.
It should be noted in toothless patients the overdenture may be supported on only two implants in the upper and lower jaw, which improves comfort in use enormously for a relatively low price, compared to full dentures.

An immediate denture is a removable prosthetic restoration given to the patient just after tooth extraction, when the patient is still under anaesthesia. All the activities related to the preparation of such a denture are done before extraction of a tooth. Such management allows the patient to avoid the discomfort related to the lack of teeth, as well as providing normal living conditions and the possibility of containing professional work. It also promotes and improves healing of post-extraction wounds. However, the use of such solution requires strict observation of the dentist's recommendations, frequent check-up visits and maintaining perfect hygiene of the oral cavity and denture.
Skeletal denture is modern removable prosthetic restoration. Such a denture is supported not only on the gums and mucous membrane, but also on teeth; thus, it does not cause increased atrophy of gums and bone tissue. Such a denture, if properly made, may be used by the patient for many years. The basic elements of the skeletal denture involve a metal base (skeleton) and acrylic elements replacing the missing tissues (teeth and base).
A bridge is a restoration permanently fixed in the oral cavity. Such a solution provides the patient with an excellent aesthetic and functional effect. The main inconvenience related to conventional bridges is the necessity of grinding of at least two teeth adjacent to the gap. Depending on the patient's preferences and localisation of the missing tooth/teeth, metal, porcelain, or complex bridges are used; the last consists of a metal framework covered with aesthetic material (porcelain, acrylic, composite) that simulates the shape and colour of the missing dentition. this type of restoration may be supported on both natural teeth and implants.
A prosthetic crown is a permanent denture covering a damaged tooth crown or replacing it, if completely lost. On the other hand very damaged teeth or these weakened by canal treatment are strengthened with root-crown inlays, which may be compared to a metal "pin" fixed in the root canal and covered with a prosthetic crown. Depending on the patient's preferences and clinical condition, metal or composite crowns are used. A prosthetic crown may be placed on both natural teeth and implants.
The introduction of implants into dentistry has revolutionised modern prosthetic, enabling completely novel therapeutic solutions. With implants used as the base, various types of prosthetic restoration, such as full overdentures, bridges replacing complete or partial loss of dentition, or single teeth may be applied (see also IMPLANTOLOGY).
