Dental Implants Vs. Bridges

Teeth go missing for a variety of reasons, usually due to accidents or decay. While some teeth are more necessary than others, it is important to replace these teeth to avoid further dental damage. Dental implants and bridges are the two most common ways to replace teeth.

How They're Made

• Most dental implants are made of commercially pure titanium screws. Dental bridges are traditionally made of porcelain, to mimic the tooth, fused to metal bracing. Some porcelain bridges can stand on their own. Bridge dimensions are determined by a formula known as Ante's Law.

Installation

• Installation of a dental implant begins with drilling into the bone. The titanium screw is then placed into the drilled hole and time is allotted for the bone to begin growing around the screw. Once this takes place, a tooth is placed over the screw. The bridge process begins by shaving down the tooth or teeth bordering the missing tooth to allow room for the bridge. The porcelain tooth is fused to the metal bracing and the tooth is placed into the gap, with the bracing falling behind the teeth. The bracing is then affixed to the teeth.

How They Work

• Dental implants are fused to the bone, effectively becoming a new tooth. Bridges are more similar in function to dentures. They are fixed in place but are not attached to the jaw.

Warnings

• When inserting dental implants into the back of the lower jaw, there is a heightened risk of striking the mandibular nerve. Bridges are less durable than dental implants. Additionally, there is a heightened risk of cavities in the adjoining teeth when a bridge is used.

Misconceptions

• Bridges are similar to, but are not, dentures. Most bridges cannot be slipped in and out and have a relatively long life span if taken care of.
