How Many Teeth Can Implants Replace?
Selecting the best tooth replacement option usually depends on the number of teeth missing. While dental implants are the ideal replacement option for one tooth, replacing several missing teeth, or a span of teeth, may lead a patient to consider other options, such as an implant-supported bridge. Below is more information about the tooth replacement treatment and the benefits it offers.
What Is an Implant-Supported Bridge?
An implant-supported bridge functions like a traditional bridge, but instead of being supported by adjacent teeth, it is secured to titanium posts embedded in the jawbone.
An implant-supported bridge is an effective option for replacing several missing teeth. One bridge can replace between 2-14 missing teeth. The number of implants depends upon the number of teeth missing; more implants will be placed to support a larger bridge. In general, two dental implants can support three to four artificial teeth, and four to six implants can support an entire upper or lower arch of teeth.
The Benefits of an Implant-Supported Bridge
There are many benefits implant -supported bridges have to offer, including:
- A more permanent restoration that is securely placed in the mouth
- Restoration of biting, chewing, eating, and speaking function
- Easy daily cleaning with good oral hygiene habits
- Titanium implant posts that replace the tooth root, stimulating the jawbone
- Implants that may be even stronger than natural teeth
One of the biggest benefits is that implant-supported bridges cost less than replacing each missing tooth with an individual implant. This is because the bridge requires fewer total implants. If feasible and affordable, the best option for long-term oral health, function, appearance, and jawbone is to have individual implants and crowns installed for each missing tooth. The artificial implant roots ensure healthy gums and jawbone. An implant-supported bridge is the next best option.
Different Implant Bridge Designs
There are several different implant bridge designs for the dental provider to choose from, depending on the number of teeth to be replaced. A few of the most common designs include:
- 3-4 tooth implant-supported bridge: This common bridge is designed to replace a span of three to four teeth with implants placed in the jawbone at the ends of the gap. The bridge is then secured to these implants.
- Cantilever implant bridges: This design is intended to support fewer replacement teeth, usually supporting a length that is less than half the total length of the entire bridge. This design might be the best solution if there is not enough room to place multiple implants.
Implant Supported Bridges vs. Traditional Dental Bridges
A traditional dental bridge can replace several missing teeth and is secured by fitting it tightly to nearby dental crowns. Alternatively, an implant-supported bridge looks more natural, functions like natural teeth, and has the potential to last for decades without replacement. If taken care of with good daily hygiene practices and regular dental visits, implant-supported bridges are more durable and secure than a traditional dental bridge.
