In the types taxonomy, material science defines market value. PEEK commands the largest revenue share (42 %) because its modulus approximates cortical bone, permitting large-span implants without stress shielding; hospitals accept a >2× price premium over metals. Titanium mesh and solid Ti6Al4V plates retain 33 % of dollar sales, favoured for rapid production and osseointegration, yet pricing pressure is rising as generic CNC centres commoditise simpler geometries. PMMA patient-matched constructs hold 15 %, used mainly in emergent trauma where sterilisation turnaround is critical; however, bio-inertness limits long-term adoption. Hydroxyapatite-reinforced PEEK and biodegradable PLLC composites comprise the 10 % "others" category, capturing research-driven centres focused on osteoconduction and paediatric applications where resorbable implants mitigate growth restriction.
