Modified Titanium Dental Implants: The Current Progress of Soft‐Tissue Integration Methods
Advanced NanoBiomed Research, EarlyView.Dental implants are an established solution for tooth loss, yet achieving soft tissue integration (STI) around the transmucosal region remains a challenge. The natural tooth–gingiva interface is poorly replicated on titanium implants. This review explores surface modification strategies, ranging from surface chemistry and topography to biological ...
