Biocomposite films based on PLA reinforced with different β-TCP contents (10%, 20%, and 25%wt.) were fabricated via solvent casting and immersed in SBF for 7, 14, and 21 days. The bioactivity, morphological, and thermal behavior of composites with immersion were studied using scanning electron microscopy (SEM), energy-dispersive X-ray (EDX) microanalysis, weight loss (WL), X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR), differential scanning calorimetry (DSC), thermogravimetric analysis (TGA), and gel permeation chromatography (GPC). This broad analysis leads to a deeper understanding of the evolution of the polymer–filler interaction with the degradation of the biocomposites. The results showed that β-TCP gradually evolved into carbonated hydroxyapatite as the immersion time increased. This evolution affected the interaction of β-TCP with PLA. PLA and β-TCP interactions differed from PLA and carbonated hydroxyapatite interactions. It was observed that β-TCP inhibited PLA hydrolysis but accelerated the thermal degradation of the polymer. β-TCP retarded the cold crystallization of PLA and hindered its crystallinity. However, after immersion in SBF, particles accelerated the cold crystallization of PLA. Therefore, considering the evolution of β-TCP with immersion in SBF is crucial for an accurate analysis of the biocomposites’ degradation. These findings enhance the comprehension of the degradation mechanism in PLA/β-TCP, which is valuable for predicting the degradation performance of PLA/β-TCP in medical applications.

Due to its excellent biocompatibility, high mechanical strength, and favorable aesthetic effects, zirconia ceramics is considered as a potential dental implant material. However, the biological inertness of zirconia results in a lack of osseointegration. Herein, a newly modified zirconia ceramic with 58S bioglass (BG) is fabricated via vacuum pressure infiltration method. The effects of BG sol infiltration time on the microstructure, phase composition, mechanical properties, mineralization ability, surface profile and roughness, ions release, protein adsorption, and cell behavior in vitro of zirconia ceramics are investigated. The zirconia ceramics have a micronano surface structure as well as active ions’ releasing ability, improving the osseointegration ability of it synergistically. Compared to unmodified zirconia ceramics, BG‐modified zirconia ceramics not only maintains excellent mechanical strength, but also can enhance the bioactivity, cell adhesion, spreading, and osteoblast differentiation. Besides, the results of q‐polymerase chain reaction show that BG‐modified zirconia ceramics can promote the expressions of osteogenesis‐related genes, including collagen type I (Col‐I), osteocalcin (OCN), osteopontin (OPN), and runt‐related transcription factor 2 (Runx2), compared to the control group. In summary, research suggests that BG bioactive zirconia ceramics can be a potential candidate for dental implant.
