Dental Implants
Overview of Dental Implant Placement
Tooth Replacement Options
What are Dental Implants?
A natural tooth consists of a root and a crown. If you compare natural teeth to implant-supported replacement teeth, you’ll see they have the same basic parts. Both have a crown (the visible part used to chew food). Both have a root that holds the tooth securely under the gum and is anchored into the jaw. The difference is that the implant is made of titanium – the same time-tested material used by surgeons for artificial joints. When you lose a tooth, you lose both the root and the crown. To replace the tooth, the surgeon first replaces the root with a small dental implant.
Time is allowed for bone to heal and grow around the dental implant. The bone bonds with the titanium, creating a strong foundation for artificial teeth. A support post (abutment) is then placed on the implant and a new replacement tooth (crown) is placed on top of the abutment. In many cases a temporary replacement tooth can be attached to the implant immediately after it is placed. If all of your teeth are missing, a variety of treatment options are available to support the replacement teeth.
The surgical procedure
The procedure to place an implant takes 30 to 60 minutes for one implant and only 2 to 3 hours for multiple implants. The number of appointments and time required, vary from patient to patient.
Prior to surgery, you may receive antibiotics. A local anesthetic will be administered to numb the area where the implant will be placed. Local anaesthetic works very effectively on gum and bone so most patients find implant surgery just as comfortable as modern dental procedures. If you are nervous or anxious the procedure can be done under general anaesthesia.
When you are comfortable, the Periodontist makes a small incision in the gum tissue to reveal the bone, creates space using special instruments, and gently inserts the titanium implant. The top of this implant is often visible through the gum. Sometimes it is better in the early stages of healing to have the implant covered by the gum tissue.
The healing process
Now the healing begins. The length of time varies from person to person, depending upon the quality and quantity of bone. In some cases, implants may be restored immediately after they are placed. The surgeon will advise you on follow-up care and timing. After the initial phase of healing, the surgeon places an abutment (support post) or a healing cap onto the implant during a brief follow-up visit. This allows gum tissue to mature and provides access to the implant.
Occasionally, impressions or a digital scan are made at the time the implant is placed. This enables the crown to be ready when the implants have healed. How long your mouth needs to heal is determined by a variety of factors. Follow-up care (one to four appointments) is usually needed to ensure that your mouth is healing well and to determine when you are ready for the restorative phase of your treatment.
It may be beneficial to perform a soft tissue graft to obtain stronger, more easily cleaned and natural appearing gum tissue in the area around the implant. This process involves moving a small amount of gum tissue from one part of your mouth to the area around the implant. Most often, it is a brief and relatively comfortable procedure.
Whether it’s one tooth or all of your teeth that are being replaced, your dentist will complete the restoration by fitting the replacement tooth (crown) to the dental implant.

How many implants do I need?
If you have multiple missing teeth it is not necessary (or even beneficial) to have one implant for every missing tooth. Bridgework can be attached to strategically placed implants to replace the missing teeth.
Note: Any surgical or invasive procedure carries risks. Before proceeding, you should seek advice from an appropriately qualified health practitioner.
