What are Standard Dental Implants?
A dental implant is really a very simple metal screw which is designed to thread into the bone of the jaw and to allow for the attachment of a (prosthetic) tooth at the top. Implants are made of Medical grade Titanium or Titanium Alloy. Your dentist will purchase the implants in sterile packaging and place them in a small hole in the bone which he or she has prepared as part of the implant placement procedure. The bone will fuse to the implant over a short period of time in a process referred to as 'osseointegration' and once this process is successfully completed (3 to 6 months) the implant is permanently in place.
Types of Implant
- Single tooth replacement
- Multiple tooth replacement
- Denture Stabilization
Single tooth replacement
A single Implant is used to replace a single tooth, can be used both in the front of the mouth and the back of the mouth
Central Incisor :

Lateral Incisor:

Back Molar:

Multiple tooth Replacement:
Can be used to replace teeth in the form of a Bridge ( teeth joined together ) or with multiple individual teeth
Two Molars and a Premolar:

Full mouth replacement:
Replacing upper teeth with a fixed Porcelain Bridge

Replacing upper teeth with a fixed Porcelain Bridge

Denture Stabilization:
Denture Clicks in and out using precision attachments on at least two Implants

Strong, durable, and natural in appearance, implants are among the most successful dental procedures performed. Although you have a number of restorative options for the treatment of missing teeth, none has proven to be as functionally effective and esthetically natural as implants. In many cases, dental implants may be the only logical choice for the restoration of all necessary functionality of the teeth and supporting structures.
Advantages of Implant Dentistry
Dental implants are stronger, more durable, and more natural than their restorative counterparts (bridges and dentures). Implants offer a permanent solution to tooth loss.
- More attractive appearance.
- Great comfort.
- Don't need to drill into the teeth on either side.
- Helps prevent bone loss due to tooth removal.
- Greater ability to chew food.
- No rubbing, clacking, or pain.
- No cream or adhesives.
- Not having to take out at night.
- Not overnight soaking in a glass.
The Dental Implant Procedure
1. Initial Consultation
The Implant process needs three people; The Surgeon to place the Implant, the Dental technician to make the tooth and the Dentist to connect the tooth to the Implant and oversee the process. The first step is an examination and consultation. This usually involves
x-rays and may include taking impressions for models of your teeth. If you
have already lost a significant amount of bone, additional x-rays taken at
another facility that specializes in this type of x-ray may also be
recommended. During the examination, we will be evaluating the area(s) of your mouth
where teeth are missing, including the amount of bone available to support
the placement of implants. we will also be evaluating the type of
replacement teeth that will best meet your needs. A review of your health
history will indicate whether there are any medical conditions that could
prevent you from being a candidate for implant treatment.
2. Dental Implant Placement Procedure
The dental implants are placed in the bone using a gentle surgical
technique. The Surgeon places a small-diameter hole (pilot hole) at edentulous (where there is no tooth) jaw sites in order to guide the titanium screw that holds a dental implant in place. To avoid damaging vital jaw and face structures like the inferior alveolar nerve and the mandible (lower jaw), a Surgeon must use great skill and expertise. After the initial pilot hole has been drilled into the appropriate jaw site, it is slowly widened to allow for placement of the implant screw. Following this placement, a protective cover screw is placed on top to allow the implant site to heal and the dental implant to anchor (osseointegration).
3. Abutment Attachment Procedure
Following the appropriate bone remodeling period, a small connector post
called an abutment is attached to each dental implant. The permanent
replacement teeth will eventually be attached to the abutments.
4. Fabrication of Replacement Teeth
A series of appointments will be needed to take impressions of your teeth
and the implant abutments; place temporary replacement teeth; select the
appropriate shade for your replacement teeth and try them for proper fit. In
between these appointments, the laboratory technician will fabricate your
replacement teeth and the underlying structures that will be attached to the
dental implants.
5. Completion of Dental Implants
Once the above phases are complete, then your new dental implants will be
fixed to the abutment and you'll have a beautiful new set of teeth that
look, feel and function just like the real thing.
6. Ongoing After Care
Regular examinations will be necessary to monitor and maintain you Implants to ensure that any problems are caught early, this will help ensure the best chance for longevity
Today's dental implants are virtually indistinguishable from other teeth. This appearance is aided in part by the structural and functional connection between the dental implant and the living bone. Implants are typically placed in a single sitting but require a period of osseointegration.
Osseointegration is the process by which direct anchorage of a dental implant root and the bone of the jaw occurs. Osseointegrated implants are the most commonly used and successful type of dental implant. An osseointegrated implant takes anywhere from three to six months to anchor and heal, at which point your dentist can complete the implant procedure. Once the implant has anchored with the jawbone, an artificial prosthesis (tooth) may be attached and the process is done. If osseointegration does not occur, the implant will fail. Detailed procedural steps are as follows:
What are the Risks?
- In rare circumstances Implants have been known to fail and they will have to be removed through a subsequent procedure. ( usually just unwinding them by hand )
- It is possible that implant superstructure may fracture during the implant’s life cycle, and in the event a fracture were to occur, the fractured implant may be removed or left in the jaw if its causing no problem, determined by professional judgment.
- If the patient keep good oral hygiene and does not return for return for appropriate post-operative care including plaque removal, Implants can fail.
- The use of tobacco, including cigarette smoking as well as excessive alcohol consumption can cause failure of the dental implants.
- Swelling, infection, bleeding and/or pain may be associated with any surgical procedure, including Implants and the said conditions may occur during the life of the implants.
- Temporary or permanent numbness may occur in my tongue, lip(s), chin, or jaws as a result of this procedure as well as the possibility of sinus involvement in my upper jaw. Although cases occurring with Mini Implants are extremely rare
Does the Procedure Hurt?
It is often done under local anesthesia and patients generally experience some discomfort after the procedure although this is usually controlled by paracetamol. It is similar to having a simple tooth extraction.
Success Rates of Dental Implants
Dental implants are among the most successful procedures in dentistry. There is no guarantee that an implant procedure will be successful, but studies have shown a five-year success rate of 95% for lower jaw implants and 90% for upper jaw implants. Many other studies have shown 5 year success rates in the high nineties. The success rate for upper jaw implants is slightly lower because the upper jaw (especially the posterior section) is less dense than the lower jaw, making successful implantation and osseointegration potentially more difficult to achieve. Upper posterior implantation has the highest failure rate for all dental implants.
Dental implants may fail for a number of reasons. The cause is often related to a failure in the osseointegration process. For example, if the implant is placed in a poor position, osseointegration may not take place. Dental implants may break, become loose, have a higher than normal peri-implant bone loss, or become infected. If you are a smoker who is considering a dental implant, your dentist will likely advise you to give up smoking before undergoing the process because smokers face a higher risk of implant failure. Since the procedure can be extremely expensive, you risk wasting your money on dental implants if you do not give up the habit.
On the plus side, dental implants are not susceptible to the formation of cavities; still, poor oral hygiene can lead to the development of peri-implantitis around dental implants. This disease is tantamount to the development of periodontitis (severe gum disease) around a natural tooth.
Implant Dentistry: New Procedural Strategies
Experienced implantologists have begun to use a new strategy for the replacement of missing teeth. Dental implants are placed into locations where teeth have recently been extracted. When successful, this new strategy can shed months off of the treatment time associated with dental implants because osseointegration is sped up. Candidacy for this type of early intervention is dependant upon anatomical factors of the extracted tooth site. For example, in many cases the extracted tooth site is wider than the implant, making it impossible to place the implant into the site immediately after extraction. Dental work would have to be performed first in order to create a perfect fit for the implant.
Another strategy for implant placement within narrow spaces is the incorporation of the mini-implant. Mini-implants may be used for small teeth and incisors. Get more information about alternatives to traditional implants by checking out our mini implant section.
