Implant retained bridges vs Bar over-denture pros & cons?

As you know there are pros and cons to every treatment you undergo. If is important to understand what it is you want.   The first decision is whether you want fixed or removable teeth.  In both cases the aesthetic results in the hands of professionals is the same.  The next question is the material you want the teeth to be made of.  Teeth can be made of acrylic (plastic), porcelain (glass) or Zirconia (ceramic).  Plastic teeth tend to wear and pop off, porcelain tends to chip, Zirconia is virtually indestructible.   Today you also have the option of having ceramic implants placed instead of titanium.In terms of cost for a bar overdenture on 4-6 implants you are looking at $15-25,000 per arch and for a full arch fixed on 4-8 implants $20-40,000 per arch.  These are difficult decisions to make. Go see some doctors and look at their before and after pictures. Make
sure you ask for pictures where you can see the gums. Most before and
afters in implant dentistry show the smile only, tells you nothing about
the surgical work. You need to see what the gum to tooth interface
looks like. Is the color of the gum, the height of the gum, the
consistency of the gum same as the other teeth? Do you see dark lines?
Is the doctor giving you all possible options with the latest proven materials and techniques?These are the important things to evaluate before choosing your doctor.

The best and most expensive treatment (if you have sufficient bone) is FIXED crown and bridge over 6-8 implants per jaw. To have one jaw completed would cost $40,000 to $50,000 or close to $100,000 for both in a specialists office. Bar over dentures in both jaws would cost around $20,000. However, there is a world of difference between them with regards to comfort and esthetics. Bridges are made of porcelain so they look real and very esthetic. Dentures still move even if they are stabilized by implants and don't feel as secure. 

The type of prosthesis that you have selected is one that retains the prosthesis, but does not support the prosthesis. This means that you will have a full denture and the tissue and bone will support the prosthesis. The denture will have its normal break in period where you will have to get the sore spots adjusted. After the denture is adjusted, the implant units will be activated to keep the denture down. In most instances today, we do not use bars for this. We use an individual attachment for each implant. This is much more cost effective tan a bar.
