A fixed dental bridge cannot be removed. Its usually ore comfortable. It is more convenient. Its more friendly to the surrounding tissue because it eliminates the insertion and removal process that may cause harm. However, it is more expensive and requires preparation of the teeth adjacent to the empty space. A removable appliance is less convenient because it cannot be worn all the time. It is generally recommended that its removed during bed time. It can cause harm if its not properly designed to the surrounding tissue, simply by the need or placement and removal. However, it is generally cheaper. But usually takes more visits to fabricate.

The disadvantages of a girder bridge is that it's expensive to build. It is also very hard to maintain. It needs to have access to the confined space of the girderbox.
sky bridge has a lot of Adventages
write it properly here
The advantages of a bascule bridge is swiss cheese with a dash of pepper
One big disadvantage is that rust isn't as strong as new steel, so enough rust and the bridge might collapse. They look ugly, too.
The main advantage of a cable-stayed bridge is that it is under compression by the cables which makes it stronger. The main disadvantage of the cable-stayed bridge is that it is more susceptible to wind than other types of bridges.
Advantage: It is strong. Also the cables won't break under extreme temperatures. Disadvantages: Wind is a big factor. It can rock the bridge side to side, causing the cables to become lose.
well really go online and look it up on ask.com its not that hard to do
ADVANTAGES 1.It yields simple expressions for unknown inductance and capacitance. 2.The two balanced equations are indepent of frequency. DISADVANTAGES 1.Low Q-Coils. 2.Variable capacitor is required.
Disadvantage: An arch bridge requires a very stable foundation. The bridge diverts the tension exerted on it onto the foundations on either side of the bridge. Advantage: It is an economical way to traverse small distances and is able to cope with bending forces
