Implant retained denture Bowmanville

We first saw Helen as a patient for an implant consult after the last few remaining teeth supporting her lower partial denture broke and were no longer repairable.  She was comfortable with her upper complete denture and was aware that a lower complete denture is often very difficult to use for chewing and often is very unstable. Helen had a denture made to be inserted at the time of teeth removal on the bottom.  4 Immediate dental implants (implants placed at the same time of extractions) were placed in the lower jaw and allowed to heal for 4 month by Dr Mark Bishara. Why was Helen a good candidate for these procedures? Helen was a good candidate for this procedure as long term wear of a loose lower denture can cause even greater bone loss.  Most often patients don’t wear their lower dentures as it gets looser or end up…

Dental Implant Dentures Info

Implant retained dentures or simply called implant over-denture are dentures that retained by a number of dental implants. Patients sometime ask how many implants are needed to retain their denture in place. This varies greatly by the region of the jaw (upper or lower) and whether we are making a full denture or partial. For the sake of assumption, let us assume a patient has a complete full denture on both the top and bottom jaws.  A lower denture requires two to four implants to stabilize it.  The minimum is two but it works alot better with four. For an upper jaw, we usually like to use anywhere between four to six implants to retain the denture.   This is because the upper jaw is softer in density and we need to compensate for this with extra implants. Below is an example of an upper denture with 5 implants to…

The history of dental implants

Dental Implants have been around for some time believe it or not! The picture above has a nice illustration of the history time line of how we got here today! Dr Branemark an orthopedic surgeon accidentally discovered that titanium can ‘fuse’ to bone during experiments on rabbits. So dental implants have been around for over 40 years with modifications to technique and their surfaces to help maintain bone and increase healing.

Dental CT Scans, Why do we use them?

In certain situations where a tooth has been missing for some time or there are no teeth present and we wish to have a precise measurement of the bone area underneath, we ask patients that they have something called a CT scan of the area.  A traditional dental x-ray is 2 dimensional and has limitations as it only shows available bone height.  A CT scan takes a 3-d image of the area that we are interested in.  This tells us how wide and tall the bone area is and also reveals other important areas such as your sinuses, nerves near the planned surgery area.

Bone Loss and Tooth Extractions Explained

Often before we jump in to an extraction, we like to spend the time discussing with the patient options for down the road.  Bone loss happens as a natural process after a tooth is removed. The bone will start to remodel and change shape gradually. It can happen faster or slower for each person and also depending on which region of the jaw.  The jaw bone is much softer in the upper jaw and bone loss is faster. We like to think of bone as a muscle, very similar to a muscle in use it becomes stronger.  Without stimulation or from denture pressure on the gum tissue only, the bone will start to shrink. Does a bridge or denture cause your bone loss to stop from shrinking? The answer is no.  A bridge has something called a pontic (fake tooth) that rests above the missing space and is joined to adjacent teeth.…
