Summary
Steel-ceramic Fastened Partial Denture (FPD) are nonetheless most generally used within the
final decade. A mechanical failure as lack of ceramic from the metallic when the FPD
was acquired a mastication power equivalent to in compressive, tensile and shear power, is
usually happen. In order that, the bond power between metallic and ceramic supplies could be very
essential for the medical success of restoration. There are some elements which may
have an effect on the bond power of metal-ceramic, both in medical elements equivalent to
restoration’s design, or laboratory elements equivalent to sort of metallic, metallic floor
remedy, utility approach and firing means of porcelain. Porcelain’s firing
course of together with time, temperature, firing quantity, and atmospheric strain. This
research goals to find out the affect of temperature and firing quantity of opaque
porcelain within the bond power of metal-ceramic FPD.
This analysis is an experimental laboratory. Manufacture of metal-ceramic
samples included 30 samples which had been finished within the Laboratory of Dental Unit Take a look at
FKG USU. Steel-ceramic samples had been divided into six teams, which include
opaque porcelain firing temperature in 950 ºC and 975 ºC with firing quantity of
opaque porcelain in 1 time; 2 instances; and three instances. Measurement of the bond power
values was finished by utilizing three level bending instrument on a common testing
machine. Impact of opaque porcelain firing temperature in 950 ºC and 975 ºC with
firing quantity in 1 time; 2 instances; and three instances in opposition to the bond power of metalceramic
FPD had been analyzed by T-test. Affect of opaque porcelain firing quantity in
1 time; 2 instances; and three instances with firing temperature in 950 ºC and 975 ºC with in opposition to
the bond power of metal-ceramic FPD had been analyzed by one-way ANOVA.
Variations between impact of opaque porcelain firing temperature in 950 ºC and 975
ºC with firing quantity in 1 time; 2 instances; and three instances in opposition to the bond power of
metal-ceramic FPD had been analyzed by LSD take a look at.
Outcomes confirmed that there was the affect of opaque porcelain firing
temperature in 950 °C and 975 °C with firing quantity in 1 instances, 2 instances and three instances
in opposition to the bond power of metal-ceramic FPD. There was the affect of opaque
porcelain firing quantity in 1 time; 2 instances; and three instances with firing temperature in 950
ºC with in opposition to the bond power of metal-ceramic FPD. There was the affect of
opaque porcelain firing quantity in 1 time; 2 instances; and three instances with firing
temperature in 975 ºC with in opposition to the bond power of metal-ceramic FPD. There
was variations in impact of opaque porcelain firing temperature in 950 °C and 975
°C with firing quantity in 1 instances, 2 instances and three instances in opposition to the bond power of
metal-ceramic FPD. The best imply worth of the bond power was the opaque
porcelain firing temperature 975 °C with firing quantity in 2 instances (45.04 ± 2.30).
Statistically confirmed that essentially the most important worth of the bond power was the
opaque porcelain firing temperature 975 °C with firing quantity in 2 instances (p = zero.027). Opaque porcelain firing temperature 975 °C with firing quantity in 2 instances is
really useful as a information to fabricate of metal-ceramic FPD to supply maksimal
bond power of metal- ceramic, with a view to acquire long-term medical success in
metal-ceramic FPD.

 

Gigi Tiruan Cekat (GTC) keramik-logam merupakan jenis gigi tiruan yang
paling banyak dipakai dalam dekade terakhir. Kegagalan mekanis berupa lepasnya
keramik dari logam saat GTC menerima gaya pengunyahan dalam wujud tekanan,
tarikan dan gaya geser, sangat umum terjadi, sebab itu ikatan yang kuat antara bahan
keramik dan logam amat penting untuk kesuksesan klinis restorasi. Faktor-faktor
yang bisa memengaruhi kekuatan lekat keramik-logam, diataranya yaitu faktor di klinik,
yaitu desain restorasi dan faktor-faktor dilaboratorium, yaitu jenis logam, floor
remedy logam, teknik aplikasi dan proses pembakaran porselen. Proses
pembakaran porselen, termasuk waktu, suhu, jumlah pembakaran, dan tekanan
atmosfer. Tujuan riset ini merupakan untuk mengetahui pengaruh suhu dan
jumlah pembakaran porselen opak terhadap kekuatan lekat GTC keramik-logam.
Jenis riset ini merupakan eksperimental laboratoris. Pembuatan sampel
keramik-logam berjumlah 30 sampel dilakukan di Unit Uji Laboratorium Dental FKG
USU. Kelompok sampel keramik-logam dibagi atas enam kelompok, yang terdiri atas
suhu pembakaran porselen opak 950 ºC dan 975 ºC dengan jumlah pembakaran
porselen opak 1 kali; 2 kali; dan three kali. Pengukuran nilai kekuatan lekat dilakukan
dengan alat three level bending pada common testing machine. Pengaruh suhu
pembakaran porselen opak 950 ºC dan 975 ºC dengan jumlah pembakaran 1 kali;
2 kali; dan three kali terhadap kekuatan lekat GTC keramik-logam dianalisis dengan uji
T. Pengaruh jumlah pembakaran porselen opak 1 kali; 2 kali; dan three kali dengan
suhu pembakaran porselen opak 950 ºC dan 975 ºC terhadap kekuatan lekat
GTC keramik-logam dianalisis dengan uji one-way ANOVA. Perbedaan pengaruh
antara suhu pembakaran porselen opak 950 ºC dan 975 ºC dengan jumlah
pembakaran porselen opak 1 kali; 2 kali; dan three kali terhadap kekuatan lekat GTC
keramik-logam dianalisis dengan uji LSD.
Hasil riset menjelaskan bahwa ada pengaruh suhu pembakaran
porselen opak 950 °C dan 975 °C dengan jumlah pembakaran 1 kali, 2 kali, dan three kali
terhadap kekuatan lekat GTC keramik-logam. Ada pengaruh jumlah pembakaran
porselen opak 1 kali, 2 kali, dan three kali dengan suhu pembakaran porselen opak
950 °C terhadap kekuatan lekat GTC keramik-logam. Ada pengaruh jumlah
pembakaran porselen opak 1 kali, 2 kali, dan three kali dengan suhu pembakaran
porselen opak 975 °C terhadap kekuatan lekat GTC keramik-logam. Ada perbedaan
pengaruh suhu pembakaran porselen opak 950 °C dan 975 °C dengan jumlah
pembakaran porselen opak 1 kali, 2 kali dan three kali, terhadap kekuatan lekat GTC
keramik-logam. Nilai rerata kekuatan lekat paling tinggi terdapat di suhu
pembakaran porselen opak 975 °C dengan jumlah pembakaran porselen opak 2 kali
(45,04 ± 2,30). Secara statistik memperlihatkan nilai kekuatan lekat yang amat
signifikan terdapat di suhu pembakaran porselen opak 975 °C dengan jumlah
pembakaran porselen opak 2 kali (p=zero,027). Suhu pembakaran porselen opak 975 °C dengan jumlah pembakaran
porselen opak 2 kali direkomendasikan sebagai panduan pembuatan GTC keramiklogam
untuk menghasilkan kekuatan lekat keramik-logam yang maksimal, sehingga
didapatkan kesuksesan klinis jangka panjang dalam pemakaian gigi tiruan cekat
keramik-logam.
