Overview

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, and most insurance carriers typically cover less than 10 percent of the fees.

The American Dental Association considers two types of implants to be safe. They are:

• 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.

What Are the Advantages of Dental Implants?

There are many advantages to dental implants, including:

• Improved appearance. Dental implants look and feel like your own teeth. And because they are designed to fuse with bone, they become permanent.
• Improved speech. With poor-fitting dentures, the teeth can slip within the mouth causing you to mumble or slur your words. Dental implants allow you to speak without the worry that teeth might slip.
• Improved comfort. Because they become part of you, implants eliminate the discomfort of removable dentures.
• Easier eating. Sliding dentures can make chewing difficult. Dental implants function like your own teeth, allowing you to eat your favourite foods with confidence and without pain.
• Improved self-esteem. Dental implants can give you back your smile and help you feel better about yourself.
• Improved oral health. Dental implants don't require reducing other teeth, as a tooth-supported bridge does. Because nearby teeth are not altered to support the implant, more of your own teeth are left intact, improving long-term oral health. Individual implants also allow easier access between teeth, improving oral hygiene.
• Durability. Implants are very durable and will last many years. With good care, many implants last a lifetime.
• Convenience. Removable dentures are just that; removable. Dental implants eliminate the embarrassing inconvenience of removing dentures, as well as the need for messy adhesives to keep them in place.

Do implants hurt?

Placing an implant is often easier than taking a tooth out and is usually done using a simple local anaesthetic. You will not feel any pain at the time but, just like after extraction, you may feel some discomfort during the week after the surgery. Sometimes your dentist might give you a sedative if you are very nervous or if the case is a complicated one. General anaesthetics are rarely used for implants and are generally only used for very complicated cases.

How long does the treatment take?

Your dental team will be able to give you a rough timetable before the treatment starts. Some false teeth can now even be fitted at the same time as the implants (these are called ‘immediate implants'). Check with your dental team to see whether these are suitable for you. Usually, the false teeth are fitted 3 to 4 months after the implants are put in. Sometimes treatment takes longer and your dental team will be able to talk to you about your treatment time.
