Dental Implants
Dental implants are fixtures of titanium which are surgically screwed into your jaw bone. The implant is an anchor for a naturally-appearing false tooth or a set of false teeth.
The success rate of dental implants depends on where the implants are placed and their purpose. They are typically best placed in the front portion of your lower jaw. Implants are great for replacing missing teeth. It is important that you have enough bone in the area of the missing teeth for the implants to be attached to.
If you don't have enough bone for this purpose, a bone graft may be necessary. If you have a small dental bridge or partial dentures (removable type), implants will be a welcome alternative. Implants are an alternative to a fixed bridge. The implant will last a lifetime, but the crown on top of it will last ten to fifteen years.

Implants are not only used to replace one tooth, but rather people missing most, if not all, of their teeth benefit greatly as well. Implants are increasingly being used to replace certain types of bridges and removable partial dentures.
Implants are surgically placed in your jaw bone while under anaesthesia. It is a very time consuming procedure when having many implants placed. As this procedure is surgical, it is very important to research and find a well credited cosmetic dentist that you are comfortable with.
For some people there are varying degrees discomfort or pain, which subsides in a couple of days. As with similar types of surgery, bruising and minor swelling might also develop shortly after the procedure. Implants require a three to six month healing period before the implant restoration to replace the missing tooth or teeth. During this healing time, the bone grows in and around the titanium implant creating a very strong support.
Dental implants can be rejected. Usually they are replaced with another implant of a slightly larger size. The rejection or "failure" rate is minimal, only 1 to 2% of all implant procedures. You must go without wearing your dentures for one day to two weeks after an implant placement. After the implant has "taken" and you have sufficiently healed, a very natural crown is placed on the implant.
Implants rely on titanium fixtures inserted into the jawbone. Most implants are made of titanium, which is very effective at fusing with living bone (osseointegration). There are three types of dental implants which your cosmetic dentist will discuss with you:
Root Form Implant
This screw type implant is shaped like the root of a tooth. This is the most commonly used implant and is used where there is plenty of width and depth to your jawbone. If your jawbone is too narrow or short for placement of the Root Form implants, bone grafting may be needed to allow for their placement. After you've received anaesthesia, your cosmetic dentist will expose an area of your jawbone and prepare the bone for the implant. The number of incisions and bone preparations depend on how many implants you need. The implant will be set into place and your gums are closed with stitches. It will take three to six months for healing. After you've fully healed, your implant is uncovered and an abutment is attached.
Plate Form Implant
If your jawbone is too narrow for bone grafting, a Plate Form implant is placed into your jawbone. The Plate Form implant is unique for this purpose as it has a flat and long shape for a better fit into a narrow jawbone. After you've received anesthesia, your cosmetic dentist will expose an area of your jawbone and prepare the bone for the implant. The number of incisions and bone preparations depend on how many implants you need. The implant will be set into place and your gums are closed with stitches. It will take three to six months for healing (some Plate Form implants are immediately ready for restoration without the long healing process).
Subperiosteal Implants
If there's not enough bone width or height for the Root Form or Plate Form implants, the Subperiosteal implant is recommended. The Subperiosteal implant is custom made to rest on top of your jawbone and under your gums like the Plate Form implant, but the Subperiosteal implant is placed through one of two special methods.
The first method of placement involves your cosmetic dentist making an impression of your jawbone. After you've received anaesthesia, the dentist exposes your jawbone and takes an impression of it. The impression is used by a dental laboratory to make a custom-fit implant for your jaw. The next procedure, after your custom-fit implant is created, is to again expose your jawbone and place the implant. Your gums are then closed with stitches and replacement teeth are installed.
The second method of placement requires a CAT scan of your jawbone. Through computer modeling techniques, a model of your jawbone is made from the CAT information. The next procedure, after your custom-fit Subperiosteal implant is created by a dental laboratory, is to again expose your jawbone and place the implant. Your gums are then closed with stitches and replacement teeth are installed.
While dentures and removable bridges are usually loose and unstable, implants provide you with dental replacements that are both natural looking and very functional. Implants look much better, and feel better, than traditional removable bridges, and offer the same force for biting as bridges that are fixed in place. Implants will last your lifetime.
Please ask your dentist for further information.

Bone Grafting
A procedure of building up the bone is known as Bone Grafting. Bone grafting is common with dental implants. The bone that is used is one of three types. The preferred bone to use is taken from other areas of your mouth or collected in a suction device as the drilling of the sites for dental implants occurs. Sometimes bone is taken from areas such as a hip (this requires an orthopaedic surgeon and an operating room). The third source for needed bone is a synthetic type. This is the least preferred type of bone to be used for this procedure.
