Does Implant Diameter Matter?

Posted on 11/9/2021 by Greg Kammeyer
Research shows that an increase in the diameter of a dental implant decreases the stress on the bone, and implant diameter is more important than length for long term success. Dentistry Journal reported that even with a 30 degree off axis implant, this is true in all 4 bone qualities.

If the surgeon is using implants that have varied abutment diameters, as opposed to systems that one abutment size fits all size implants, I have found consistently that there are NO complaints about food collection and the soft tissue is healthier around larger diameter implants. I use implants that are 3mm to 9mm in diameter.

Since the crestal 1/3rd of the bone takes all the stress from occlusion, and must be 2mm wider than the implant, often bone augmentation is necessary. This can be performed at the implant placement surgery or in an earlier phase, depending on how much bone is missing.

Lastly the wider the implant the more stable it is to occlusal forces. Narrow implants in the posterior have more micro motion where the abutment meets the implant. You'll notice this as you take off abutments and see if the area smells from bacterial activity. I’m confident that there will be less peri-implantits due to less bacterial activity.

Like so many things in Implant Dentistry, the more through we are, the fewer problems occur.
