Abstract

Introduction: This experiment was conducted experimentally to synthesize Calcia Partially Stabilized Zirconia (Ca-PSZ) by sol-gel method using eggshell membrane template as a composite filler. The eggshell membrane was used to produce a mesh shaped structure, which hopefully can improve the mechanical properties of the composite. Method: Ca-PSZ filler was synthesized from ZrOCl2 precursor and Ca(NO3)2 stabilizer with a 24 hours immersion time. Ca-PSZ of synthesis then mixed with the resin matrix to test its composite hardness. Result: The EDS characterization results suggested that the sample contained elements of zirconia, calcium, and oxygen. Whereas, the XRD characterization identified that crystal structures that formed in the sample were nano scale tetragonal. Characterization of SEM showed Ca-PSZ with mesh structured. The average composite hardness value was 15.79 VHN. Conclusion: The composites with Ca-PSZ-synthesized filler could be prepared and its hardness value was higher than the composite with Ca-PSZ filler in spherical particles, but the hardness was still below the composite on the market.

Abstract

Tinjauan pustaka ini membahas pendekatan biomimetik dalam bidang kedokteran gigi yang bertujuan untuk meniru dan menggantikan struktur alami pada area kraniofasial. Penelitian yang intensif selama beberapa dekade telah menghasilkan pengembangan biomaterial dan teknik inovatif untuk mendukung proses tersebut. Temuan menunjukkan bahwa material berbasis alami atau yang menyerupai struktur biologis memiliki hasil klinis yang lebih baik dan potensi lebih tinggi untuk aplikasi klinis. Oleh karena itu, pengembangan biomaterial biomimetik memerlukan pendekatan interdisipliner yang melibatkan kedokteran, bioteknologi, dan ilmu komputasi. Di masa depan, pengembangan jaringan gigi yang sepenuhnya diregenerasi, seperti enamel, dentin, pulpa, dan sementum, dengan karakteristik nanostruktur yang menyerupai jaringan gigi alami, menjadi salah satu harapan utama dalam kemajuan bidang ini.
