Despite the advantages of the CAD/CAM technique, including reduced ischemia time of osteocutaneous fibula flaps, there is no impact on total reconstruction time or flap survival.

Two possible mechanisms, alone or in combination, could possibly lead to MA-related ONJ. Self-extraction of teeth as a psychopathologic behavior of self-destruction among MA abusers results in wounds that allow unhindered invasion of microorganisms causing osteomyelitis and ONJ, while on the other hand, the heating of white phosphor releases toxic phosphorous vapor, which could be inhaled and consequently cause ONJ of the maxilla. However, since the worldwide prevalence of MA abuse is remarkably high, a relationship between MA abuse and ONJ will offer a new aspect in the etiology of ONJ and might present a further therapeutic challenge.
