Titanium alloys are unsuitable implants for patients with low bone quality due to their high moduli and bioinertness. In this study, porous boronized Ti6Al4V/fluorohydroxyapatite (FHA) composites synthesized via microwave sintering of mixed Ti6Al4V, FHA TiB 2 powders at 1050 °C 30 min, 0–10 wt% urea as a space holder material. It is shown that increasing addition leads higher porosity, promoting penetration “lens effect”, which improves boronization restrains degradation mechanical properties the caused by increased porosity. With 0–3 wt%, compressive strength modulus decrease from 380.3 MPa 14.5 GPa 134.4 3.26 GPa, respectively, while Vickers microhardness declines 360.3 300.0 HV. The exposure chemical biological composite, water contact angle decreased nearly half osteogenesis sixfold. By adding more urea, decreases evidently, poorer wettability biocompatibility looser structure decomposition. 3 composite achieves an optimal balance between ultralow enhanced bioactivity, making it ideal rapid osseointegration in poor conditions.

Modern dentistry is turning towards natural sources to overcome the immunological, toxicological, aesthetic, and durability drawbacks of synthetic materials. Among first biomaterials used as endosseous dental implants, mollusk shells also display unique features, such high mechanical strength, superior toughness, hierarchical architecture, layered, microporous structure. This review focusses on hydroxyapatite—a bioactive, osteoconductive, calcium-based material crucial for bone healing regeneration. Mollusk-derived hydroxyapatite widely available, cost-effective, sustainable, a low-impact biomaterial. Thermal treatment coupled with wet chemical precipitation hydrothermal synthesis are most common methods its recovery since they provide efficiency, scalability, ability produce highly crystalline pure resulting Several factors, temperature, pH, sintering parameters, modulate size, purity, crystallinity final product. Experimental clinical data support that shell-derived carbonated derivatives, especially their nanocrystaline forms, notable bioactivity, osteoconductivity, osteoinductivity without causing adverse immune reactions. These therefore relevant specific applications, graft substitutes or implant coatings. However, continued research validation needed optimize determine applicability regenerative beyond.
