Socket preservation can be done by adding biomaterials. Bovine Amniotic Membrane (BAM) is an alternative biomaterial that can be used for socket preservation. However, BAM is easily degraded due to its low mechanical properties. Because of this, BAM material can be combined with materials containing calcium and phosphate so that biodegradation can be controlled. Carbonate Hydroxyapatite (CHA) is a calcium phosphate bone substitute biomaterial that is biocompatible, bioactive and osteoconductive. Until now there has never been any research combining BAM-CHA into a bio-composite material.
This study aims to analyze the BAM-CHA bio-composite including functional groups, pore size, porosity percentage, and Ca/P ratio as a candidate material for alveolar bone sockets preservation.
BAM-CHA bio-composites with ratios of 30:70, 35:65, and 40:60 (w/w) were made using the method with Freeze-drying which was then cut into sizes of 0.5 × 0.5 cm. The samples were analyzed to functional group analysis using the FTIR method, pore size analysis using the SEM method, porosity percentage analysis using the liquid displacement method, and Ca/P ratio analysis using the EDX method.
BAM-CHA bio-composite has Amide A, B, I, II, III, and PO43-, CO32-, OH- functional groups. BAM-CHA 30:70 bio-composite has an average pore size of 105.0684 µm and the largest pore size of 203,063 µm. BAM-CHA 30:70 bio-composite has a porosity percentage of 82.40 ± 4.47%. BAM-CHA 30:70 bio-composite has a Ca/P ratio of 1.92 which is close to the bone Ca/P ratio criteria.
BAM-CHA 30:70 bio-composite has characteristics including functional groups, pore size, porosity percentage, and Ca/P ratio which are most suitable as a candidate material for alveolar bone socket preservation.
