According to a new study looking at the amount of changes in the bone around different dental implant designs, it seems that a single-piece dental implant results in the smallest amount of changes.
Studying Abutment Design
A replacement tooth is typically made up of three parts: a dental implant that goes down into the jawbone. A dental crown that sits atop the dental implant. And an abutment that connects the two.
Although this is generally a successful design, there is often reshaping of the bone around the dental implant. This can lead to cosmetic problems (such as the loss of the papillae between teeth), and, sometimes, contribute to future problems with the implant. We’re not sure why this happens, but it may be due to the bite force placed on the dental implant or due to bacteria that accumulates at the junction between the implant and the abutment.
In this study, researchers wanted to know whether the abutment design affected how well the body maintained jawbone around implants. They looked at six different designs for the implant/abutment interface:
- Both dental implant and abutment are straight and have the same diameter
- Both are straight, but the abutment is narrower.
- Single piece that is straight
- An impression in the abutment, but the abutment widens to match implant diameter
- An impression at the abutment/implant interface
- An impression in a single-piece implant/abutment
They found that the group that resulted in the least reshaping of the bone was the single-piece straight dental implant. It was significantly better than the other two straight designs. All designs with an impression in the abutment resulted in about the same amount of bone changes.
It’s important to note that all these dental implants integrated properly in the jawbone, so there isn’t really a question of any of these designs being defective: it’s a small, but significant difference in results at issue here.
