Method for preparing titanium-containing implant by using environmentally-friendly etching composition

The present invention provides a method for preparing an implant including preparing a mixed etching composition including hydrogen peroxide and a water-soluble carbonate compound and oxidatively etching an implant made of titanium or a titanium alloy by immersing the same in the etching composition; a titanium or titanium alloy implant prepared by oxidative etching with a mixed etching composition including hydrogen peroxide and a water-soluble carbonate compound; and a composition for treating surface of an implant containing hydrogen peroxide and a water-soluble carbonate compound. Further, the present invention relates to a titanium or titanium alloy implant which is prepared by oxidative etching with a mixed etching composition including hydrogen peroxide and a basic solution and on which surface bumps having continuous or discontinuous line-shaped open channel structures in nanoscale are irregularly formed, and a preparation method thereof. The surface of the titanium alloys treated with the mixed etching composition including hydrogen peroxide and a carbonate compound or the etching composition containing hydrogen peroxide and a basic solution of the present invention includes micrometer-sized bumps and channel-shaped nanometer-sized bumps, and thus has an increased surface area, and can not only improve wettability, but also effectively promote cell proliferation and osteocyte differentiation. In addition, the composition includes no chemical compounds such as a strong acid, etc. and is thus environmentally friendly, and such compounds can be prevented from remaining on the surface, which can improve biocompatibility, and therefore, the composition can be useful for implant surface treatment.

HOST MODULATING AND TISSUE REGENERATIVE HYDROGEL COMPOSITIONS AND METHODS OF THEIR DELIVERY TO PERIODONTAL AND PERI-IMPLANT TISSUES
20220111119 · 2022-04-14 ·

The present invention concerns a novel use of therapeutic hydrogels in nonsurgical techniques to promote healing and regeneration of tissues whose structure and functions have been diminished due to chronic inflammatory disorders. More particularly, the invention provides therapeutic and regenerative hydrogel compositions and their nonsurgical delivery to periodontal treatment sites to treat periodontal and peri-implant diseases. Furthermore, the invention concerns a novel technique which involves the injection of said sterile therapeutic biomimetic hyaluronic acid hydrogel to which are tethered at least one host modulating agent, such as tetrahydrocurcuminoids, THC, and at least one additional tissue regenerative agent into the gingival connective tissue proper. The host modulating agent potentiates the periodontal tissue regeneration at the periodontal treatment site, while the biomimetic hyaluronic acid hydrogel serves in a dual capacity as a drug, a tissue regenerative agent carrier and as a biodegradable matrix around which the new connective tissue can regenerate. The invention also concerns oral care gel and paste compositions of at least one host modulating agent tethered to the HA tissue regenerative hydrogel formulated to be used in a synergistic home-based oral care regimen.
