Pathophysiological Sequence:Mechanical Delamination: Under the immense, multi-directional shear and compressive forces of mastication, the unreinforced Proplast-Teflon material undergoes structural breakdown and fragmenting.Macrophage Recruitment: Microscopic particulate polymer and metal debris flake off into the joint spaces, triggering a massive influx of foreign-body giant cells and macrophages attempting to phagocytose the non-degradable particles.Cytokine Cascade: Unable to digest the debris, the immune cells release a continuous wave of pro-inflammatory cytokines (such as TNF-$\alpha$, IL-1, and IL-6).Osteolysis: This localized inflammatory storm upregulates osteoclast activity, resulting in aggressive bone resorption, destruction of the glenoid fossa and condyle, and ultimate joint collapse. convert this into image

Proplast-Teflon TMJ Implant Failure: Pathophysiological Sequence
Here is the visual diagram of the full pathophysiological sequence. It covers all four stages in a 2x2 grid layout:
  1. Mechanical Delamination - Shows the TMJ implant fragmenting under mastication forces
  2. Macrophage Recruitment - Depicts foreign-body giant cells and macrophages swarming non-degradable debris
  3. Cytokine Cascade - Illustrates the release of TNF-alpha, IL-1, and IL-6 from frustrated immune cells
  4. Osteolysis & Joint Collapse - Shows osteoclast-driven bone resorption destroying the glenoid fossa and condyle
The diagram flows sequentially from top-left to bottom-right, making the cause-and-effect chain easy to follow for presentations or study material.
