Can Bone Cement Fashioned From A 3-D Model Be Used As A Chin Implant?
Q: Dr. Eppley, I really wanted to advance my chin and make my jawline straighter. I know I will need a sliding genioplasty and perhaps bone cement along the sides of my jawline. I was wondering if what I had in mind is possible and have done my own before and after to show you whicih I have attached. I like how the part below my lip and above my chin comes out almost like the jaw was moved forward, along with the the extension of my chin and straightness of the middle part of my jawline. Is all of this possible ? I don’t want to use any kind of implant, just my bone and bone cement. Can you make a custom 3D implant mold and place bone cement in that instead of using an implant ?
A: What you are demonstrating is the classic change that would occur from a sliding genioplasty. There is no need for bone cement or 3D model fabrications to get there. The chin bone (not the jaw bone) is cut and moved forward and plated into position. While silicone synthetic implants can be made from a 3-D model you can not use bone cement to create an implant as it is too brittle.
