| dc.description.abstract | Tooth extraction can cause alveolar ridge resorption that affect the use of the denture, so it requires
augmentation to improve the contour of the alveolar ridge. Hydroxyapatite is used as alveolar ridge augmentation
material in Indonesia, they are imported at high prices and availability limited. In Indonesia, especially the area of
East Java Jember district Puger produced natural gypsum raw materials that can be developed and utilized as
hydroxyapatite. This study aims to determine how the process of synthesis and characterization Hydoxyapatit using
FTIR XRD analysis of Gypsum Puger Jember as alveolar ridge augmentation material. Methods of synthesis of
hydroxyapatite research conducted by hydrothermal technique by reaction between gypsum hydroxyapatite Puger
with DHP (diammonium hydrogen phosphate), then the result of the reaction was analyzed by XRD and FTIR testing
compared with HA 200 Japan as a comparison. The results of the analysis we found the same patterns between
Gypsum hydroxyapatite Puger with HA 200 Japan as standard. Conclusion The study has managed to synthesize
gypsum puger into hydroxyapatite / Puger gypsum hydroxyapatite (HAGP). Characterization HAGP performed by
XRD and FTIR that test results are the same, or there is a similar pattern with HA 200 Japan (standard), so HAGP is one
of the bioceramics materials that can be used as an alternative material alveolar ridge augmentation in order to use
denture can be managed properly. | en_US |
