Advantages of Maryland bridge
- Dentists find the Maryland bridge as an ultra-conservative treatment for splinting or replacing missing teeth. It is a good aesthetic way that demands minimum amount of tooth modification.
- As it combines a composite resin cemented to acid etched enamel, it is proven for its bond strength. The bond strength is almost 3 fold more than those earlier resin-bonded retainers.
- Even fixed partial dentures periodontal splints and other conservative restorations can be held with a minimum of tooth modification.
- Abutment teeth are not damaged. They are basically left intact.
Problems Associated with a Maryland Bridge:Though it is valuable, Maryland bridge has 2 main aesthetic problems in regard to the use of metal.
- The first problem is that teeth are translucent. The metal backing will cause the teeth to darken slightly. They have different color than other front teeth.
- The second problem is the false tooth is a porcelain fused to metal tooth. This fusing will make it lack the natural translucency and vitality that other teeth have in them.
