Over subsequent weeks, osteoblasts lay down new bone tissue, a process known as osteogenesis, which gradually encapsulates the screw. Titanium alloys, particularly Ti-6Al-4V, dominate the market due to their high strength-to-weight ratio, exceptional corrosion resistance, and biocompatibility.

The procedure typically involves creating a pilot hole using a tap set, which prepares the bone bed to receive the screw without causing fracture. In non-locking scenarios, the goal is often to remove the hardware after healing to prevent long-term stress shielding, whereas locking constructs are often left in place if removal poses greater risk.
Material Composition and Properties Material science is paramount in the success of bone screws, as the device must perform under demanding biological and mechanical conditions. Biological Integration and Healing Beyond the mechanical interaction, the body views the screw as a foreign object, triggering a complex biological response.

Mechanical Function and Biomechanics The primary role of screws in bones is to provide rigid fixation, holding bone fragments in precise alignment while the natural healing process takes place. Loosening or breakage of the screw can occur if the bone does not heal adequately or if premature weight-bearing is applied.
