Having just signed up for a dental implant post-graduate course in 2016, it made me realise I hadn’t done a post about these yet.
What is an implant?
As you can see in the picture above an implant is a bit like a titanium screw. A very special one that you then can attach things to, be it a crown, one end of a bridge or a special attachment which is used to help holds denture in place.
The process
Once the thorough assessment and planning has been done, if you have adequate bone in the area to hold an implant one can be placed. If not, an implant may still be possible but you may need a bone graft in order to do so.
So the first stage is placing the implant. An incision is made in the gum so that access can be made to the bone beneath and the implant placed. You would be number up to the hilt and this will feel pretty much the same as having a filling done, lot of water, some weird vibration.
With the implant in place correctly the gum is stitched back over for a few months. Life goes on as if nothing ever happened, but that implant is undergoing osseointegration; that is becoming part of the bone. These implants have very specially designed surfaces which allow the bone to fuse to them and anchor hem in strongly.
Once that has finished, the next stage is normally placing what is called the abutment, the bit that will attach to whatever is going to go on the implant. Again some time is hen needed for this to heal and the gum line to settle around it. Once that is done The final restoration can start to be made.
Occasionally some cases may be appropriate for an immediate loading implant, being that you don’t need to wait for the osseointegration bit. But this is only in specific cases so best to assume it’ll be the usual way and if you are suitable then bonus. It just speeds the process up.
Implant retained restorations
So as mentioned before an implant can then support either a single crown, one end of an implant retained bridge, or be part of a series of implants helping to hold a denture in place. With implant retained dentures, the implants will have precision attachments, either funny shaped bits, bars or magnets which have corresponding attachments embedded into the denture.
Success rates
Implants are very successful. They have the best success rates of any part of dentistry!
An article published in the British Dental Journal in 2006 states that:
“In comparison to other prosthetic designs implant single crowns had the lowest failure rate at 2.7%.”
And
“Naert et al.6 also reported a cumulative success rate of 96.5% over an 11 year period and there are numerous other studies alluding to the longevity of single unit implant restorations.7, 8, 9 Single tooth implant survival has been demonstrated to be the most predictable method of tooth replacement.”

This does mean that ultimately dental implants are very cost effective. Although there may be more expense at the start, over the long term it can work out cheaper.
For example, if you were to consider replacing an anterior tooth with a bridge vs an implant, a bridge would only be a little cheaper, but causes a lot of destruction to the supporting teeth which puts them at risk, but also will need replacing much much sooner.
So, it’s very exciting to be starting the post-graduate training in February 2016 with Tipton Training and hopefully get a PG Cert in dental implantology from the British Academy of Dental Implantology!!
