Tailoring magnesium-doped coatings for improving surface and biological properties of titanium-based dental implants.

Physicochemical modifications of biomaterials have been proposed to overcome bone integration impairment and microbial infections. The magnesium (Mg) incorporation on dental implant surfaces has shown positive results in bone-to-implant contact and in the reduction of microbial colonization. Here, we explored the potential of using different Mg precursors to synthesize coatings via plasma electrolytic oxidation (PEO) on commercially pure titanium (cpTi), aiming to optimize the surface and biological properties.

Efficacy of a novel three-step decontamination protocol for titanium-based dental implants: An in vitro and in vivo study.

Aim: The aim of the study was to evaluate several mechanical and chemical decontamination methods associated with a newly introduced biofilm matrix disruption strategy for biofilm cleaning and preservation of implant surface features.

Materials And Methods: Titanium (Ti) discs were obtained by additive manufacturing. Polymicrobial biofilm-covered Ti disc surfaces were decontaminated with mechanical [Ti curette, Teflon curette, Ti brush, water-air jet device, and Er:YAG laser] or chemical [iodopovidone (PVPI) 0.
