Mini Dental Implants for Upper Bridge: Will This Be Stable?


Bee asks:

My dentist is suggesting that I get a six (6) mini implants removable upper bridge. I am concerned about the stability of the denture with this mini implant procedure. How exactly is the denture made stable? Are there special attachments for the mini implants to make sure the denture is seated properly? Will mini implants be suitable for the upper bridge? Please Advise.

Mini Dental Implants for Upper Bridge: Will This Be Stable?

Answered By: Dr. Michael Tischler - Woodstock , NY

Dear Bee,

While 6 mini dental implants will certainly stabilize an upper denture, it does not offer the most stability of the options that are available. A bar over denture that has connected implants with a bar, offers more stability. The advantages of a bar over denture is that it supports the denture better and takes much of the pressure off of the tissue. It also allows for the denture to not cover the palate. When a denture is on tissue, bone loss occurs over time.
Another option would be an implant supported fixed bridge. These other options mentioned here have the disadvantage of having increased cost.

I would agree with Dr

I would agree with Dr Tischler, I personally do not think 6 mini implants can hold up long term to support a removable overdenture. The amount of bone around the mini-implant is minimal as compared to traditional type of implant, thus may not be able to withstand torque of chewing forces. I would get a second opinion from dentist that is a Diplomate of American Board of Oral Implantology Dentistry/Implant Dentistry (DABOI) or Fellow in the American Academy of Implant Dentistry (AAID).
Good luck

Mini Dental Implants for Upper Bridge: Will This Be Stable?

Dear Bee:
Mini implants are gaining more popularity in recent years because of their simplicity and affordability, since they require no surgery and cost about half of the price of conventional implants.
Two areas of concern about placing mini implants in the maxilla (upper jaw) is that the quality of the bone is usually not great, and the mini implants are subject to masticatory forces immediately (conventional implants when placed and loaded immediately are joined together with non removable teeth until they fuse to the bone) and you will be using a removable denture instead of something fixed.
Cases such as yours do work but present a higher risk of implants failing than conventional implants.
Good luck.

Mini Implants - The More, the Merrier

Hi Bee

Mini implants (2.0-2.5mm diam.) gain their primary stability by mechanical screw design. More implants(10-12) will give greater stability allowing a palateless denture and even fixed bridgework to be placed. There are no university studies documenting long term success with more demanding prosthetic applications. Your expectations, occlusion and skill of the implantologist influence the success.

I recommend the conventional implant in the majority of cases.
