Summary

Osteoinductive biomaterials, combining bone morphogenetic proteins (BMP) with carriers, show promise for craniomaxillofacial bone repair. Various calcium phosphate ceramics and bone matrix are effective BMP carriers in animal studies.

Background:

Osteoinductive biomaterials are crucial for craniomaxillofacial surgery, addressing intraosseous defects, contour augmentation, and segmental reconstruction.
Bone morphogenetic proteins (BMPs) combined with carrier materials create novel composite biomaterials acting as slow-delivery systems for BMP.

Purpose of the Study:

To investigate the suitability of various carrier materials for bone morphogenetic proteins (BMPs) in craniomaxillofacial applications.
To evaluate composite osteoinductive biomaterials for bone regeneration.

Main Methods:

Experimental animal studies were conducted to assess nine different calcium phosphate ceramics and inactive rat bone matrix as BMP carriers.
Composite biomaterials were developed by combining BMP with diverse organic and inorganic carrier materials.

Main Results:

All tested materials, including calcium phosphate ceramics and inactive bone matrix, proved to be suitable carriers for BMP.
The combination of BMP with different carriers allows adaptation to a wide range of clinical demands.

Conclusions:

Composite osteoinductive biomaterials utilizing BMP with various carriers show significant potential for craniomaxillofacial bone defect repair.
The investigated carrier materials are effective for slow delivery of BMP, paving the way for clinical applications.
