There are several types of dental bridges available, and the most appropriate type for you will depend on factors such as the location of the missing teeth, the condition of the surrounding teeth, and your personal preference. Here are the main types of dental bridges:
Traditional dental bridge
Traditional dental bridge is the most common type of bridge. It involves creating a crown for the teeth on either side of the gap, known as abutment teeth, and placing a pontic (artificial tooth) between them. The abutment teeth are prepared by removing a portion of their enamel to accommodate the crowns, which are then cemented onto the teeth. The pontic(s) fills the gap left by the missing tooth or teeth, restoring the appearance, function, and alignment of the smile.
Traditional dental bridges are a reliable and durable option for tooth replacement, but they do require the support of healthy adjacent teeth.
Cantilever dental bridge
A cantilever dental bridge is a type of dental bridge used to replace a missing tooth when there is only one natural tooth adjacent to the gap.
Unlike traditional bridges that require support from both sides, a cantilever bridge is supported by a single abutment tooth or dental implant on one side. The pontic (artificial tooth) is suspended over the gap, and anchored to the adjacent tooth or implant.
Cantilever bridges are a suitable option in select cases, but they may not be recommended for areas with higher biting forces or when there is an available tooth on both sides of the gap.
Maryland dental bridge (resin-bonded bridge)
A Maryland dental bridge, also known as a resin-bonded bridge, is a type of dental bridge used to replace a missing tooth or teeth. It is a conservative option that requires minimal alteration of the adjacent teeth.
A Maryland bridge consists of a pontic (artificial tooth) made from porcelain or ceramic, with small metal or porcelain wings on either side. These wings are bonded to the back of the adjacent teeth using resin cement, providing support and stability to the bridge.
The main advantage of a Maryland bridge is that it preserves the structure of the adjacent teeth since they do not need to be significantly reshaped for dental crowns. However, it is important to note that Maryland bridges are typically recommended for front teeth or areas with minimal biting forces. They may not be suitable for replacing molars or teeth subject to heavy chewing forces.
Implant-supported dental bridge
An implant-supported dental bridge is a type of dental bridge that is anchored and supported by dental implants rather than natural teeth. It is used to replace multiple missing teeth in a row.
The procedure involves the surgical placement of dental implants into the jawbone. These implants serve as artificial tooth roots and provide a stable foundation for the bridge. The number of implants required depends on the number of missing teeth and the condition of the jawbone.
Once the implants have integrated with the jawbone, abutments are attached to the implants. These abutments serve as connectors between the implants and the dental bridge. The bridge, which consists of artificial teeth (pontics) fused together, is then securely attached to the abutments.
Implant-supported dental bridges offer several advantages. They provide superior stability, functionality, and aesthetics compared to traditional bridges. They also help preserve jawbone health by stimulating natural bone growth. Implant-supported bridges are a long-lasting solution, with proper care and maintenance, and can significantly improve chewing ability and overall oral function.
That said, implant-supported dental bridges require a sufficient amount of healthy jawbone for successful implant placement. The process also involves multiple steps and may require several months to complete, including healing periods between implant placement and bridge attachment.
