What is a dental implant?

A dental implant is a substitute for the natural root of a tooth. It is commonly in the shape of a cylinder.

What is a dental implant made from?

A dental implant is generally made for titanium or a titanium alloy which has been shown to be well tolerated by bone. Just like in a hip/knee replacement, a dental implant forms a close union with the bone and integrates/heals.

How does a dental implant replace a tooth?

A dental implant is initially screwed into a precise location of where the final intended tooth is to be. Once the dental implant has integrated into the bone around it, a crown in a shape of the final tooth is then screwed on top of the dental implant.

How many teeth can be replaced by dental implants?

Dental implants can replace a single tooth up to a full arch. The number of implants required to replace multiple teeth will depend on the position of the natural teeth to be replaced, the amount of bone present in the area and the quality of the bone.

In both the upper and lower arch a minimum of 4 dental implants is required to replace a full arch of teeth.  This is what is commonly referred to as the “all on four” implant restorations. 4 implants are placed in specific locations to provide support for a full arch of teeth.

A dental implant can also be used to help provide support for a denture to prevent rocking and sliding of the denture. This can improve the comfort and stability of your full lower denture.

Am I suitable for a dental implant?

If you are in good general health then you are most likely suitable for a dental implant. Habits such as smoking and heavy drinking will affect the healing rate of dental implants and we highly advise that you stop these habits before getting a dental implant. As always, your dentist will go through your medical history to make sure that there is no other factors that can affect the overall success rate of your implant.

It is also important to make sure that the overall health of your mouth is good. The presence of periodontal disease (gum disease) and dental abscesses are associated with a high failure rate of dental implants. It is ideal that these conditions are treated before commencing dental implants.

How long does the treatment take?

The integration of a dental implant to the bone can vary depending on the quality of the bone. People who have good quantity and quality of bone can expect to heal anywhere to 12-16 weeks. Cases where the quality of bone is quite poor then a minimum of 6 months healing time is required.

What determines whether I have enough bone and the quality of bone is good?

A Cone beam CT xray is required to examine the amount and quality of bone . Research shows that some people can lose up to 30% of bone around the extracted tooth site within the first year. Preserving the bone around an extraction socket can minimise this bone loss . Preservation of the socket is achieved by placing a bone graft within the socket at the time of the tooth extraction.

What implants and bone graft materials do you use?
