Defnisi Bioceramics

Bio disini berarti Biomaterialadalah materialpasi yang digunakan dalam dunia kesehatan,yang akan diinteraksikan dengan sel-sel hidup.

Ceramics berarti benda yang memiliki long-range order crystal arrangement.

to perform with an appropriate host response in a specific

application.

Hydro+iapatite (HA

HA adalah salah satu yang paling banyak digunakan

biomaterial untuk rekonstruksi kerangka dan aringan gigi

karena siatnya yang tidak beracun dan biokompatibel

bahan yang dapat digunakan dengan aringan tulang(Nemirkol et al., *)*

emilihan biomaterial yang tepat sangat diperlukan dalam

proses pengganti tulang, antara lain mudah diperoleh,

biokompatibel, eekti, dan tidak toksik (iyani, *))#.

Hydro+iapatite (HA

roses pembuatan hidroksiapatit dari limbah tulang sapi dia/ali

dengan dikumpulkannya limbah tulang sapi, kemudian direndam

dalam air yang telah ditambahkan cairan antiseptik. 0etelah itu,

tulang sapi direndam kembali dengan Na1H, lalu dicuci

menggunakan air mengalir. 0elanutnya, tulang dikeringkan

secara alami. 0etelah itu, tulang dipanaskan pada temperatur '))

. 0etelah proses pemanasan, material hidroksiapatit dihaluskan

menggunakan stemper dan mortir hingga berbentuk serbuk.

0erbuk itulah yang disebut dengan serbuk hidroksiapatit yang

dapat digunakan sebagai bahan tambal gigi (2usuma/ardani,
