Bone growth occurred mainly in the cortical areas, and the bone bridge can be formed when the implants are installed into distal regions. |

PEEK |
Bone formation: the Si3N4 group (52.6%) was greater than PEEK (27.9%). BIC ratios and biodynamic stability: comparable. |

Femoral marrow cavities in rabbit |

In vivo test results showed that Si3N4 implants were permeated by new mature bone after being inserted into femoral massow cavities for three months. |

Si3N4 shows good biocompatibility and presumably better osseointegration than Al2O3. |

These osteofixation system showed satisfactory results in terms of the aspects of biocompatibility and mechanical stability. |

The results showed that in some implants, the depth of newly formed bone was greater than 3 mm after 3 months in situ, which meant that a porous structure is beneficial for achieving skeletal attachment. |
