OBJECTIVE

To evaluate mechanical strength of three methods of polymethyl methacrylate skull implant fixation in two experimental models.

MATERIAL AND METHODS

The first experiment was performed on a plastic model that was as close as possible to bone in structural characteristics. The second experiment was performed on a biological specimen (a ram’s head). We assessed the quality of implant fixation to bone window edges by craniofixes, ties and microscrews and lateral intercortical screws.

RESULTS

Craniofixes are feasible for small flat flaps, but not advisable for wide highly curved implants. They are also the most expensive method of fixation. Implant fixation by ties and microscrews is a universal method comparable in price to craniofix. Lateral intercortical fixation is effective both for small flat implants and wide implants with large curvature. However, this method is not always applicable.

CONCLUSION

Combined fixation by lateral intercortical screws and ties allows for the most effective fixation while reducing the overall price of consumables.
