The results revealed that tissue/bone sections of silica containing implants and implants, composed of a 1 1 mixture of silica-containing microspheres and silicatein-containing microspheres, show an enhanced regeneration of bone tissue around the microspheres, compared to the control implants containing only β-TCP.
After 6 weeks, bone blocks containing implants were harvested and transplanted into the sinus area protruding 3 to 4 mm.
Relatively numerous osteoblasts on bone trabeculae surfaces were noted in periscaffold bone tissue histological sections prepared from bone fragments containing implants harvested in the 6th week after the surgery, which means that the osteogenesis process is still running.
Immunohistochemistry. Sagittal slices of kidney containing implants were processed in paraffin, sectioned, and processed for horseradish avidin-biotin immunoperoxidase staining SP-20011; Vector LaBurlingame, Burlingame, CA) using a mouse monoclonal CD31 anti-human antibody (Dako Cytomation, Carpinteria, CA).
Sagittal slices of kidney containing implants were dehydrated in graded ethanol baths, embedded in glycol methacrylate (Technovit 7100; Heraeus Kulzer GmBH, Wehrheim, Germany), sectioned (5 μm), stained with hematoxylin and eosin (H&E), and scanned into an Aperio ScanScope CS microscope (Aperio Technologies, Vista, CA).
At 3 and 7 days after implantation, 6 animals from each group were sacrificed by intracardiac injection of T-61 (embutramide 200 mg, mebenzonium iodide 50 mg, and tetracaine hydrochloride 5 mg, per mL) (Intervet, International B.V .. Abdominal wall pieces of 2 cm containing implants on top were explanted.
In fact, metal allergic patients may well tolerate the respective metals containing implant [ 8, 19].
In the next step the slices of bone containing implant were decalcified using 4 wt% nitric acid (HNO3) for 24 hours.
The total area that contains implanted atoms after annealing is therefore called a diffusion layer.
In general, they are not recommended for use in scaffold-associated cell-based therapies, but may be used to contain implanted MSCs within defect areas when scaffolds are not used [ 84].
The tibias containing the implants were fixed in 4% neutral-buffered formaldehyde, dehydrated, and embedded in methyl methacrylate.
