A fixed (non-removable) appliance is called a dental bridge. It is the most excellent way to replace missing teeth.
There are several types of bridges. The most popular type is the traditional bridge which is made of porcelain fused to metal. This are the most popular because they resemble your natural teeth. This type of bridge consists to two crowns that go over two anchoring teeth (abutment teeth) and are attached to pontics (artificial teeth), filling the gap created by one or more missing teeth.
Dental bridges are highly durable and will last many years, however due to normal wear , they may need replacement or need to be re-cemented.
