A dental implant is surgically inserted into the jawbone where teeth are missing to support an artificial replacement tooth. Dental implants Sydney are considered permanent and irreversible once they have been implanted. Implants can be made from titanium metal or titanium-reinforced ceramic.
There are two types of implants: subperiosteal and endosteal. Subperiosteal dental implants are surgically placed on the jawbone, taking bone from other parts of the face to support a crown about two millimetres above the gumline. Endosteal implants take bone from another part of the face where the jawbone has been removed or compromised by tooth extraction. Once the titanium implant is fixed into the bone, the surrounding tissue grows over it and fuses. Implants are commonly used in conjunction with dental bridges or dentures.
A dentist will first take an impression of your mouth to plan out which implants need to be placed and how many teeth require replacement. A dental technician then takes an impression of your mouth to make the post or tooth replacement. This technique is known as indirect denture treatment. The implant posts are then screwed into place, allowing for artificial teeth to be placed on top.
A dentist may use both types of implants depending on the jawbone condition and what they want to accomplish. There are three main dental implants: single tooth, fixed partial denture, and fixed complete denture.
A single-tooth implant is used when only one tooth needs to be replaced.
A fixed partial denture is placed when several teeth need replacement in the upper or lower jaw, but not all of them.
A complete fixed denture is used when all the natural teeth are missing. The implant posts are attached to a metal framework that keeps artificial teeth stable. A gum-coloured material called “resin” covers the posts and acts as a tooth root, which allows it to attach firmly to your jawbone.

Single implants are usually placed at either end of a tooth missing, and a pontic (false tooth) lays in between. This type of implant uses small posts with the implant is placed directly under the gumline, so there’s no visible sign after treatment. Fixed denture implants are made to fit either the upper or lower jawbone depending on what dentures need to be supported.
A dentist will use a CT scan to locate the area where the implant posts should be screwed in, and then they will also take an MRI to get a detailed image of the bone. If it’s your first dental implant, you may not need an X-ray unless they find that you have special circumstances such as cysts, tumours or jaw fractures.
Before the surgery starts, you will be given anaesthesia, so you are unable to feel pain. Then an incision is made where the implant posts need to go, and the gum tissue is lifted away from the bone. Next, the titanium post is attached to your jawbone by screwing it in place, and then a temporary replacement for your upper and lower teeth is placed where the newly implanted posts are.
After looking at the jaw from both a front and side view, a dentist will determine if more implants need to be placed to accommodate all the missing teeth. In some cases, a second incision may be made on the other side of your mouth when implants are placed in another area. Once this is completed, the temporary teeth are removed, and a permanent replacement for your upper and lower jaw will be attached to the posts.

These implants can take up to several months before they’re ready for jawbone fusion due to how much time it takes for your gums to heal completely after surgery. As a result, implants that aren’t functioning well may need to be removed and replaced with another post. This may happen if you notice that your jawbone isn’t fusing correctly or if the implant is shifting out of place.
