Can Resorbable Screws Used in Sliding Genioplasties Be Seen On An X-ray?

Q: Dr. Eppley, Hello, I am curious if the resorbable lag screws that can be used in a sliding genioplasty go unnoticed in dental x-rays and x-rays in general? If so, how long does it take for the complete healing and for the lags screws to be reabsorbed? Will it be 100% undetectable? Thanks!

A: Resorbable lag screws have a limited role in sliding genioplastics to more moderate sized advancements that follow the osteotomy line. But when used their resorption time is 9 to 12 months. At this point the residual screw hole will still be seen in an x-ray but that will go on to fully fill in with bone by 18 to 24 months after surgery. The resorbable screws are never seen in an x-ray, but it is the holes in the bone that will be radiographically visible for some time.
