Hemophilia causes prolonged coagulation time due to deficiency of intrinsic pathway clotting factors (Factor VIII in Hemophilia A, Factor IX in Hemophilia B). This results in prolonged activated partial thromboplastin time (aPTT) and whole blood clotting time. Leukemia may cause bleeding due to thrombocytopenia or leukostasis but not primarily prolonged coagulation time. Pernicious anemia and malignant neutropenia do not directly affect coagulation cascade.

Explanation: Natural dentition can typically withstand average biting forces of around 600N, which is significantly higher than the 110N that complete dentures can generally handle. Complete dentures rely on muscular and bony support and are limited by the resiliency of the soft tissues in the oral cavity.

Awake fibreoptic intubation is preferred for skull base fractures to avoid accidental intracranial placement of the tube (a risk with blind nasal intubation) and to manage potential cervical spine injuries.
