Bone tissue formation within a sintered microporous glass‐fiber network implanted in extraction sockets in the rat

Abstract: – Implants were prepared by sintering glass‐fibers into a three‐dimensional network with meshes smaller than 20 μm. Oblong 5x2x0.15 mm sheets of the test material were implanted in maxillary incisor alveoli in eight white rats. The alveoli were closed with a suture in the overlying mucosa. After 3 months the animals were sacrificed and sections from the site of implantation prepared. In three animals only root remnants were found but in the remaining five the implants were wholly or partially embedded in bone … Show more

“…In the past, critical pore size for bone development has been thought to be in the range of 75-150 jim (Natiella, 1986), but varying results have disputed that. In one study, material with pores 20 ^im in diameter and 75 |im deep was implanted and mineralized tissue formation in the pores was found (Ehmford et al, 1980). Similarly, Eggli et al (1987) found that HA and TCP cylinders with pore size ranges of 50-100 pm showed higher ingrowth of bone than implants with pore sizes of 200-400 |am.…”
