Dental Implants

The best option available to replace missing teeth?

Dr Keith Doonan, a dental implant expert of North Brisbane, discusses what implants are, why they are often a favoured option for missing teeth, and what is involved in preparing and fitting them.
Dental implants are the most successful form of treatment available for the replacement of missing teeth. They look and feel more like natural teeth than any other option available.


What are dental implants?

Implants are titanium screws which are so biocompatible that bone can grow onto their surface.

QDS Dental - Dental Implants: What are they?There are usually three parts to an implant:
• the implant itself (which is buried in the bone),
• the crown (which is the part that looks like the tooth)
• and the abutment (which connects the implant to the crown).


Dental Implants are screws which are screwed into the jaw bone. A tooth can then be screwed or cemented onto it through the use of an abutment (connector). Patients often ask for a dental implant, but what they really want is a tooth. An implant is only one way to replace a missing tooth. The most qualified person to give advice on replacing missing teeth is a dentist who has undertaken further study in Prosthodontics.

Dr Keith Doonan is a dentist with a Masters in Prosthodontics together with many years of experience of both fitting implants and of lecturing internationally on innovations in this field. Keith can advise you of all your options and the pros and cons of each. To explore options contact us.


QDS Dental, Maleny - Osseointegration Dental ImplantsThe miracle of Osseointegration

Up until around the 1940s it was believed that the human body could tolerate but not integrate with implanted metallic materials. Metal plates made of Stainless Steel and Cobalt Chrome were widely used at this time to repair fractured bones.


Then, some medical researchers, Bothe, Beaton & Davenport, found that Titanium appeared to fuse with bone and was almost impossible to remove. This fusion of titanium and bone was later extensively studied and named Osseointegration. It is because of Osseointegration that modern dental implants enjoy such high success rates.

QDS Dental Maleny - Implants Through The AgesFrom Ancient Origins to Titanium

Dental implants have been around since ancient Egyptian times. Keith has said that “It is believed they were not used on men as they have only been found in mummies!”

It is only since they have been made from Titanium Metal that they have achieved a high level of success and predictability. This began around 1960 in Sweden and Italy.

Type 4 Titanium is the strongest form of commercially pure titanium available. Some implants are made from Type 5 Titanium Alloy which is not commercially pure.

Dental implants should not be placed until growth has stopped, which is usually around 18 years of age. Most patients, who are in good general health with good oral hygiene, are suitable for dental implants although a thorough oral and medical assessment is required to make the final decision.


There are a number of factors that might slightly increase the chance of implants not working as well as they should, these include:
• lack of bone
• an active gum disease
• poorly controlled diabetes
• bisphosphonate medication
• poor oral hygiene
• smoking
• certain systemic diseases


QDS Dental - Senior Woman with Healthy TeethHow long does it take to fit a dental implant?

It is possible to fit a dental implant in just one day! However, we would recommend you follow a slower path, which is more predictable and costs less. After all, this is something we hope will last you for a very long time!

Usually, we will wait 6-12 weeks after taking the tooth out before placing the implant.
When we place the implant we wait around 6-12 weeks for the bone to attach to it.

It usually takes around 2 to 4 weeks to make the final crown.

There are a number of factors that can cause the process of fitting a dental implant to take longer but in general we can complete an implant in around 3 to 6 months depending on the complexity. Or we can do it in a day in certain specific situations if you are willing to accept an increased chance of complications and expense.
