| dc.description | Latar Belakang: Bahan basis gigi tiruan yang selama ini banyak digunakan di
kedokeran gigi adalah resin akrilik. Namun basis gigi tiruan resin akrilik sering
mengalami patah. Sehingga peneliti-peneliti mengembangkan bahan basis gigi
tiruan berbahan thermoplastic nylon. Akan tetapi, belum ada rekomendasi
mengenai ketebalan optimum dari sudut pandang ilmiah. Syarat mekanis basis gigi
tiruan adalah memiliki kekuatan fleksural yang baik, dikarenakan mewakili
gerakan-gerakan mastikasi. Salah satu yang mempengaruhi adalah ketebalan basis.
Tujuan Penelitian: Untuk mengetahui perbedaan kekuatan fleksural bahan
thermoplastic nylon pada ketebalan 1 mm, 1.5 mm, 2 mm, dan 2.5 mm.
Metode Penelitian: Penelitian ini merupakan penelitian eksperimental laboratoris.
Sampel yang digunakan berupa plat thermoplastic nylon sejumlah 16 plat yang
dibagi menjadi 4 kelompok ketebalan (1 mm,1.5 mm, 2 mm, dan 2.5 mm). Plat
thermoplastic nylon kemudian diuji kekuatan fleksuralnya.
Hasil penelitian: Hasil uji One-Way Anova kekuatan fleksural, didapatkan nilai p
0.016 (p<0.05), terdapat perbedaan kekuatan fleksural yang bermakna terhadap
ketebalan thermoplastic nylon (p<0.05). Rerata kekuatan fleksural terendah pada
ketebalan 2.5 mm. Rerata kekuatan fleksural tertinggi pada ketebalan 1 mm.
Kesimpulan: Terdapat perbedaan kekuatan fleksural bahan thermoplastic nylon
pada ketebalan 1 mm, 1.5 mm, 2 mm, dan 2.5 mm. Semakin tebal plat thermoplastic
nylon, maka gaya fleksural maksimalnya cenderung semakin naik, namun kekuatan
fleksuralnya cenderung semakin turun. | en_US |
| dc.description.abstract | Background: Denture base material that has been widely use in dentistry is acrylic
resin. However, the resin acrylic denture base often breaks. So researchers have
been develop new denture base material made from thermoplastic nylon. But, there
is not clarified design (include the optimum thickness) of the thermoplastic nylon
from the scientific point of view yet. The mechanical properties of the denture base
is have good flexural strength, as it represents mastication movements.
Objective: To know the differences of thermoplastic nylon’s flexural strength at
thickness 1 mm, 1.5 mm, 2 mm, and 2.5 mm.
Material and method: This study is a laboratory experimental study. Samples used
in this study are 16 plates of thermoplastic nylon which were divided into 4 groups
of thickness (1 mm, 1.5 mm, 2 mm, and 2.5 mm). The thermoplastic nylon plate
was tested its flexural strength.
Result: One Way Anova test of flexural strength, shows the p value is 0.016 (p
<0.05), it means there is a significant difference of thermoplastic nylon’s flexural
strength to its thickness. The highest mean of flexural strength is at 1 mm, and for
the lowest flexural strength is at 2.5 mm.
Conclusion: There is a difference in flexural strength of thermoplastic nylon
material at thickness 1 mm, 1.5 mm, 2 mm, and 2.5 mm. The thicker thermoplastic
nylon plate, the maximum forces of flexural tend to increase, but the flexural
strength tend to decrease. | en_US |
