Purpose of the Study:

• To review the application of layer-by-layer (LbL) assembly for surface modification of dental titanium implants.
• To explore how LbL techniques can promote osteogenesis, osseointegration, and soft tissue healing.
• To summarize LbL's role in improving antibacterial properties and enabling drug delivery from titanium implants.

Main Methods:

• Utilizing layer-by-layer (LbL) assembly, a self-assembly technique for creating multilayer films.
• Applying LbL to modify the surface of titanium and titanium alloy dental implants.
• Reviewing studies on LbL-modified titanium for enhanced biological and therapeutic functions.

Main Results:

• LbL assembly effectively modifies titanium implant surfaces.
• Surface modification promotes osteogenesis and osseointegration.
• LbL techniques improve antibacterial properties and facilitate localized drug delivery.

Conclusions:

• Layer-by-layer assembly offers a versatile approach for dental titanium implant surface modification.
