Dental implants are metal posts or frames that are surgically positioned into the jawbone beneath your gums. Once in place, they allow your dentist to mount replacement teeth onto them.
How do Dental Implants Work?
Because implants fuse to your jawbone, they provide stable support for artificial teeth. dentures and bridges mounted to implants won't slip or shift in your mouth-an especially important benefit when eating and speaking. This secure fit helps the dentures and bridges — as well as individual crowns placed over implants — feel more natural than conventional bridges or dentures.
For some people, ordinary bridges and dentures are simply not comfortable or even possible, due to sore spots, poor ridges or gagging. In addition, ordinary bridges must be attached to teeth on either side of the space left by the missing tooth. An advantage of implants is that no adjacent teeth need to be prepared or ground down to hold your new replacement tooth/teeth in place.
To receive implants, you need to have healthy gums and adequate bone to support the implant. You must also commit to keeping these structures healthy. Meticulous oral hygiene and regular dental visits are critical to the long-term success of dental implants.
Implants are usually more expensive than other methods of tooth replacement.
There are two types of implants that have been extensively tested:
- Endosteal implants — these are surgically implanted directly into the jawbone. Once the surrounding gum tissue has healed, a second surgery is needed to connect a post to the original implant. Finally, an artificial tooth (or teeth) is attached to the post-individually, or grouped on a bridge or denture.
- Subperiosteal implants — these consist of a metal frame that is fitted onto the jawbone just below the gum tissue. As the gums heal, the frame becomes fixed to the jawbone. Posts, which are attached to the frame, protrude through the gums. As with endosteal implants, artificial teeth are then mounted to the posts.
How Long do Dental Implants Last?
Implants generally last 10-20 years, depending on the location of the implant and patient compliance with oral hygiene and dental visits. Because molars receive more stress and wear and tear, these implants typically do not last as long as implants located at the front of your mouth.
