Supporting data for “Surface Modification Aspects of Resin-based and Titanium Biomedical Implants”

Objectives: The growing demand for implants, coupled with the limited availability of materials, poses a significant clinical challenge. Consequently, the study objective was to devise a novel approach that subverts the conventional paradigm by developing a high-strength material capable of being utilized in any dental resin composite system and amenable to 3D printing. Materials and Methods: The resin-based HA-composites were synthesized by mixing 2 wt.% of nano-hydroxyapatites (nHAPs, D: 50-200 nm) and 10-20 wt.% of submicron-glass particles (D<700nm) with photocurable dental resin monomer system. The samples were randomly divided into a control and a test group with or without helium-oxygen cold plasma treatment, and polyetheretherketone (PEEK) were used as a control. Results: With the increased glass particle fillers fraction, the mean value of the compressive strength and modulus increases from 104.04 to 121.25 MPa (16.5%) and from 2.18 to 3.41 GPa (56.4%), respectively. Conclusion: Collectively, the metal-free medical implants possessed strong mechanical strength, and its water contact angle enhanced through cold plasma surface treatment.
