ABSTRACT

Fibre posts were introduced around two decades ago with the promise of

having similar modulus of elasticity of dentin, which were not present in rigid cast

metal posts. With cast metal post, teeth were at risk of root fracture due to being

highly rigid and possibility of corrosion. Carbon fibre posts, eventhough had

successfully overco

me the problem of rigidity, still weren’t able to restore teeth

esthetically.

Glass fibre post were then introduced along with other tooth-coloured posts,

enablin dentists to create a more pleasant and natural-looking esthetic restoration.

In comparison to other type of posts, glass fibre posts were found to have higher

flexural strength, allowing better distribution of stress along the tooth structure,

and highly resistant to fracture. In cases of failure, conditions were favourable and

the tooth can be restore again. Glass fibre posts were able to bond to any

composite material and cheaper since it can be completed in one visit. In cases of

retreatment, removal of post was easier.

ABSTRAK

Pasak fibre telah diperkenalkan sejak dua dekade lalu karena memiliki modulus elastisitas

mirip dentin, hal ini tidak dimiliki pasak cor logam yang kaku. Penggunaan pasak cor logam

memiliki risiko fraktur akar karena kekakuan tinggi dan memungkinkan korosi. Pasak carbon

fibre, walaupun berhasil mengatasi masalah kekakuan itu, tetapi masih belum bisa

merestorasi gigi secara estetik.

Pasak glass fibre kemudian diperkenalkan bersama pasak berwarna gigi yang lain, agar

dokter gigi dapat menghasilkan restorasi yang estetik yang terlihat lebih indah dan alami.

Bila dibandingkan dengan pasak jenis lain, pasak glass fibre diketahui memiliki kekuatan

lenturan tinggi, memberikan distribusi tekanan yang lebih baik sepanjang struktur gigi, dan

sangat tahan terhadap fraktur. Keuntungan lain ialah, jika terjadi kegagalan, gigi masih bisa

direstorasi lagi. Pasak glass fibre dapat berikatan pada semua jenis komposit dan lebih

murah karena bisa diselesaikan dalam satu kali kunjungan. Pada perawatan ulang, pasak

bisa diambil dengan mudah.
