μ-CT analytical images of periimplant bone tissues after 4 weeks of implantation in the healed mandibular edentulous site of the rat. (A, B) Two-dimensional (2D) and (C) 3D μ-CT images of bone tissues. In the in vivo model, lower first molars of SD rats were extracted, and the extraction site was allowed to heal for a duration of 2 and 4 weeks (A) and the changes in the periimplant tissue and position of N-Ti and GN-Ti implants were determined at 4 week via 2D μ-CT monitoring (B). After 4 weeks, the thickness of the newly formed bone surrounding the implant was determined by 3D μ-CT; gray represents the implant and pink depicts the bone tissue (C) (n = 10, each group).

μ-CT, microcomputed tomography; SD, Sprague Dawley; 3D, three-dimensional; GN-Ti, Korea Red Ginseng extract–loaded titanium nanotube; N-Ti, titanium nanotube.
