Abstract

Cranioplasty dilakukan untuk merekronstruksi tulang kepala yang mengalami defek serta mempertahankan estetika bentuk kepala. Implan yang digunakan untuk mengganti tulang adalah acrylic bone cement dengan komposisi utama polymethyl methacrylate (PMMA) yang dapat dibuat dengan ZrO2 sebagai radiopaque agent sekaligus meningkatkan kekuatan mekanik
serta mempermudah pengamatan pasca operasi. Kegagalan implan yang kerap terjadi pasca operasi akan merugikan baik pihak pasien maupun pihak rumah sakit. Revision surgery akibat
gagalnya material implan bertahan dalam jangka waktu tertentu dapat memberikan resiko gagal operasi kepada pasien bila terjadi secara tiba – tiba. Penelitian ini dilakukan untuk menganalisis pengaruh lama perendaman dalam larutan simulated body fluid (SBF) sebagai simulasi ketika bone cement diaplikasikan di dalam tubuh terhadap strukur kimia dan morfologi acrylic bone cement yang dapat berpengaruh pada kemampuan mekanik. Penelitian ini dilakukan dengan
variasi rasio powder banding liquid bone cement sebesar 1.5:1 dan 2.0:1 yang kemudian akan dilakukan perendaman masing – masing dengan jangka waktu 0, 1, 3, dan 6 bulan. Untuk mengetahui pengaruh lama perendaman terhadap morfologi dan struktur kimia serta kekuatan tekan pada penelitian ini dilakukan pengujian fourier transform infrared Specstroscopy (FTIR), x-ray diffraction (XRD), scanning electron microscopy + energy disperse X-ray (SEM + EDX), mapping, dan weight change. Perendaman yang dilakukan pada masing – masing sampel tidak menunjukkan perubahan yang signifikan dalam strukrur kimia penyusun acrylic bone cement namun terdapat penambahan gugus -OH pada range wave number 3500 – 3000cm-1 yang muncul karena sampel menyerap air dari larutan SBF. Berat yang dimiliki masing – masing sampel tidak mengalami perubahan yang signifikan karena berada di bawah 5%. Terjadi penurunan kekuatan tekan dengan rentang 136.20 – 205.41 MPa sejalan dengan lama nya perendaman namun uji tekan yang diperoleh masih berada di atas ASTM F415

Cranioplasty is performed to reconstruct defective skull bones and to maintain the aesthetic shape of the head. The implant used for bone replacement is acrylic bone cement,
primarily composed of polymethyl methacrylate (PMMA), which can be combined with ZrO2 as a radiopaque agent. This combination provides mechanical properties and facilitates
observation post–surgery. Implant failure, which frequently occurs post-surgery, can be detrimental to both patients and healthcare providers. Revision surgery due to the failure of the implant material to last for a certain period can pose a risk of surgical failure if it occurs suddenly. This study aims to analyze the impact of immersion duration in simulated body fluid (SBF) as a simulation of bone cement application within the body on the chemical structure and
morphology of acrylic bone cement, which could affect its mechanical properties. The study was conducted with variations in the powder-to-liquid ratio of bone cement at 1.5:1 and 2.0:1, with immersion periods of 0, 1, 3, and 6 months. To evaluate the effects of immersion duration
on morphology, chemical structure, and compressive strength, Fourier Transform Infrared Spectroscopy (FTIR), X-Ray Diffraction (XRD), Scanning Electron Microscopy with Energy
Dispersive X-Ray (SEM-EDX), mapping, and weight change tests were performed. Immersion of the samples did not show significant changes in the chemical structure of acrylic bone cement, but there was an increase in -OH groups in the wave number range of 3500–3000 cm�1, indicating water absorption from the SBF solution. The weight of each sample did not experience significant changes, remaining below 5%. There was a decrease in compressive strength corresponding to the duration of immersion, but the compressive strength remained above ASTM F415 standard.
