Laser-induced antibacterial coating on the surface of an individual titanium membrane designed by a neural network

Abstract

In modern dentistry dental implants are widely used to replace lost teeth. However, the placement of an implant may not be possible due to bone atrophy. One of the most modern ways to restore jawbone after atrophy is the use of barrier membranes. This paper proposes a method to design and create an improved barrier membranes using neural networks and laser technology. This development allows to obtain a personalized titanium membrane with a laser-induced antibacterial coating. At the first step the membrane is designed based on CT scan of the patient using 3D modeling software and convolutional neural network U-net, which allows us to reduce modeling time. The second step is to create membrane by micromilling from a titanium block. Finally, at the third step we create antibacterial membrane surface under laser oxidation and UV-activation of singlet oxygen production on the surface.
