Abstract

Aim: The aim of this study was to evaluate the bond strength of soft lining
material to polyamide denture material.

Materials and
Methods: Twenty-five polyamide denture base materials and soft
denture lining material were used in this study. The samples were divided into
five groups according to the surface treatments:

Group 1 (Control): No surface treatment

Group 2: Samples were sandblasted with 5o µm Al₂O₃
powder.

Group 3: Samples were grinded with a diamond bur.

Group 4: Samples were etched with % 37 Orthophosphoric
acid.

Group 5: Retention holes were slotted with diamond bur
to samples.

Then the samples were tested in tensile mode in a
universal testing machine at cross-head speed of 0.5 mm/min. The statistically
analysis of obtained data were performed with use one-way analysis of variance
test.

Results: The results showed that the highest bond strength value (92.54 N) was
identified in Group 3, the lowest bond strength value (31.56 N) in Group 4. The
result of one-way analysis of variance test showed that there were not
statistically significant differences between the groups. (p>0.05)

Conclusion: As a result of this study, the surface treatments were not affected on
bond strength of soft lining material to polyamide denture material.

Key
Words: Polyamide denture, soft lining materia 

YUMUŞAK
ASTAR MADDESİNİN POLİAMİD KAİDE MATERYALİNE BAĞLANMA DAYANIMI

Amaç: Bu çalışmanın amacı yumuşak astar maddesinin poliamid kaide maddesine
bağlanma dayanımının incelenmesidir.

Gereç ve
Yöntem: Çalışma kapsamında 25 adet poliamid kaide maddesi ve
bir yumuşak astar maddesi kullanıldı. Örnekler yüzey işlemlerine göre beş gruba
ayrıldı:

Grup 1 (Kontrol): Hiçbir yüzey işlemi uygulanmadı.

Grup 2: Örnekler 50 µm partikül boyutlu Al₂O₃
tozu ile kumlandı.

Grup 3: Örnekler elmas frezle aşındırıldı.

Grup 4: Örnekler % 37’lik ortofosforik asit ile
asitlendi.

Grup 5: Elmas bir frezle örneklere retansiyon olukları
açıldı.

Örnekler universal test cihazında 0.5 mm/min başlık
hızı ile test edildi. Verilerin istatistiksel analizi tek yönlü varyans analizi
testi ile yapıldı.

Bulgular: Sonuçlar en yüksek bağlanma dayanımı değerinin (92.54 N) 3. Grupta, en
düşük bağlanma dayanımı değerinin ise (31.56 N) 4. Grupta olduğunu gösterdi.
Tek yönlü varyans analizinin sonuçlarına göre gruplar arasındaki farkın
istatistiksel olarak anlamlı olmadığı görüldü (p>0.05).

Sonuçlar: Yüzey işlemlerinin yumuşak astar maddesi ile poliamid kaide maddesi
arasındaki bağlantı kuvvetini etkilemediği sonucuna varıldı.
