PERBANDINGAN PROSES PENYEMBUHAN TULANG ANTARA IMPLANTASI HIDROKSIAPATIT NANOKRISTALIN DAN HIDROKSIAPATIT MIKROKRISTALIN (Kajian pada tulang tibia kelinci

Abstract

Latar belakang. Salah satu bahan alloplastik yang berkembang pesat saat ini yaitu hidroksiapatit (HA) sintetik. Hidroksiapatit sintetik konvensional yang banyak digunakan saat ini yaitu hidroksiapatit mikrokristalin dimana struktrur kristalnya berada dalam kisaran mikrometer. Beberapa dekade terakhir bentuk nanokristalin dari hidroksiapatit (10-100 nm) mendapat perhatian dari banyak peneliti terutama mengenai sifat fisik, mekanik, kimia dan biologisnya karena hidroksiapatit nanokristalin ini lebih menyerupai bentuk hidroksiapatit alami yang terdapat pada tulang dibandingkan hidroksiapatit mikrokristalin. Tujuan dari penelitian ini adalah untuk mengetahui perbandingan proses penyembuhan tulang antara implantasi hidroksiapatit nanokristalin dan hidroksiapatit mikrokristalin. Metode. Jenis penelitian adalah eksperimental dengan hewan coba kelinci berjumlah 18 ekor dibagi dalam 2 kelompok periode dekapitasi yaitu 9 ekor kelinci pada periode dekapitasi 2 minggu dan 9 ekor kelinci pada periode dekapitasi 4 minggu. Masing-masing periode dekapitasi ini kemudian dibagi lagi menjadi 3 kelompok lagi yaitu kelompok implantasi hidroksiapatit nanokristalin, kelompok implantasi hidroksiapatit mikrokristalin dan kelompok kontrol. Data dianalisis menggunakan uji statistik Kruskal wallis dan Mann Whitney U. Hasil. Pertumbuhan tulang baru yang ditunjukkan kelompok HA nanokristalin lebih tinggi dibandingkan HA mikrokristalin secara bermakna pada periode 2 minggu (p = 0,00). Pertumbuhan tulang baru yang ditunjukkan kelompok HA nanokristalin juga lebih tinggi dibandingkan HA mikrokristalin secara bermakna pada periode 4 minggu (p = 0,006). Kesimpulan. proses penyembuhan tulang pada implantasi hidroksiapatit nanokristalin lebih cepat dibandingkan proses penyembuhan tulang pada implantasi hidroksiapatit mikrokristalin.
