How much does a suspension bridge cost
Dental bridges are made from a wide variety of materials and in different designs. Basically there are precious metal-containing, precious metal-free (ceramics) and mixed materials (ceramics and metal). The cast bridge is a metal bridge manufactured using the casting process. It can be made from precious metals (gold alloys) and non-precious metals. Non-precious metal is cheaper, but for aesthetic reasons it should be used in the area of the teeth that are not visible. The full ceramic bridge is made of ceramic (non-precious metal) materials. Precious metal-free materials can be Cerec, press ceramics and zirconium oxide ceramics. Cerec is calculated and milled by the computer, press ceramics are liquefied and pressed into shape and zirconium oxide ceramics are all-ceramics made in the dental laboratory. Ceramic dental bridges are particularly compatible and look very natural. There is also the veneer dental bridge. Here, a tooth-colored veneer made of plastic or ceramic is applied to a metal framework (metal or precious metal). This veneer dental bridge can be designed as a full or partial veneer.
If teeth are missing, a dental bridge can close the gaps between the teeth. A temporary restoration is often used until the definitive dental bridge has been made. Temporary dental bridges are made of simple plastic and are inserted immediately after the abutment teeth have been prepared. However, these temporary bridges must be handled carefully so that they do not fall out prematurely.
DENTAL BRIDGE AS LONG-TERM PROVISORY
If the number of teeth is greatly reduced, the neighboring teeth and the gums often have to be renovated. This often takes a long time. Therefore, a dental bridge is used as a long-term temporary. This consists of a metal frame so that the tooth gap and the treated gums remain sufficiently stable until the actual treatment.
If the natural teeth are healthy and stable in the jaw, a fixed bridge can be used. Fixed bridges only require one crown per abutment tooth, are firmly glued in and cannot be removed. Spans of up to 3 missing teeth next to each other in the posterior area and 4 missing teeth in the anterior area can be bridged.
If rows of teeth are interrupted by missing teeth, there is a gap. A switching bridge is used here for correction. This consists of 2 interconnected, crowned teeth that carry the pontics and replace missing teeth. To ensure that the switching bridge is stable, there should be as many abutment teeth as possible.
If at least 5 natural teeth remain after a tooth loss, but they are not in good condition, a telescopic bridge is used. The telescopic bridge is a combination of a fixed bridge and a removable partial denture. For this purpose, the damaged teeth are crowned with gold and the visible crowns are incorporated into a removable bridge.
If several teeth are missing in a row, an implant bridge can be placed on the dental implants fixed in the jaw. There is the pure implant bridge and the composite bridge, in which your own teeth are used as pillars for stabilization. The implant bridge often consists of mixed materials (ceramic and precious metal).
COMBINATION BRIDGE (HYBRID BRIDGE OR COMPOSITE BRIDGE)
The combination bridge is used for large tooth gaps, when a dental prosthesis can be inserted between natural teeth and an existing dental implant. A combination bridge is made fixed or partially removable.
ADHESIVE BRIDGE (MARYLAND BRIDGE)
The adhesive bridge is a fixed denture and is used when teeth are not in place or when teeth are lost when the dentition is damaged. The adhesive bridge consists of a metal frame or a ceramic frame and is attached to the enamel of the abutment teeth with an attachment plastic.
If the last tooth in the row of teeth is missing, the two teeth in front of the gap are crowned and connected to one another. This will only hold the replacement tooth on one side. Because of this, the bridge is less stable. This is only recommended if the crowned abutment teeth can withstand the load.
Here the dental bridge is only attached to two inlays of the neighboring teeth. This procedure is gentle on the teeth, but leads to the inlays becoming detached in the medium term and is therefore rarely practiced.
