Amaç: Bu çalışmanın amacı geleneksel ısı ile polimerize olan akrilik rezinin tamirinde, tamir yüzeylerine uygulanan farklı mekanik yüzey işlemlerinin akrilik rezinin transvers dayanımına etkisini araştırmaktır.

Gereç ve Yöntem: Özel bir kalıp yardımıyla dikdörtgenler prizması şeklinde 160 adet akrilik rezin örnek hazırlandı ve tamir yüzeylerine farklı işlemler uygulamak üzere 4 farklı gruba ayrıldı; Grup 1 işlem uygulanmayan kontrol grubunu, Grup 2 kumlama uygulanan grubu, Grup 3 plazma uygulanan grubu ve Grup 4 Er:YAG lazer uygulanan grubu temsil etmektedir. Yüzey işlemlerini takiben tamir yüzeyleri taramalı elektron mikroskobu (SEM) ve enerji dağılımı spektroskopi (EDS) kullanılarak incelendi. Daha sonra örnekler otopolimerizan akrilik ile tamir edilerek yine dikdörtgenler prizması şeklinde (65×10×3.3 mm) toplam 80 adet örnek (n=20/grup) elde edildi. Tamir edilen örneklerin transvers dayanımı ısısal döngü uygulandıktan sonra üç nokta bükme testi ile üniversal test cihazı kullanılarak ölçüldü. Sonuçların istatistiksel analizi tek yönlü ANOVA ile yapıldı ve sonrasında Tukey HSD testi kullanılarak gruplara ait ortalamalar karşılaştırıldı. Sonuçlar α=0.05 için anlamlı kabul edildi.

Bulgular: Grup 2 (27.06 ± 5.02 MPa) ve Grup 4 (26.06 ± 3.44 MPa), kontrol grubuna (Grup 1; 18.26 ± 5.27 MPa) ve Grup 3’e (11.19 ± 2.73 MPa) göre istatistiksel olarak anlamlı şekilde daha yüksek transvers dayanıklılık değerleri gösterdi (p<0.05), Grup 3 (11.19 ± 2.73 MPa) tüm gruplardan istatistiksel olarak anlamlı şekilde daha düşük transvers dayanıklılık değerleri gösterdi (p<0.05).

Sonuç: Geleneksel ısı ile polimerize olan akrilik rezinin otopolimerizan akrilik rezin ile tamirinde, tamir yüzeylerine kumlama veya Er;YAG lazer uygulaması akrilik rezinin transvers dayanımını arttırırken, plazma uygulaması transvers dayanımı azalttı.

Objective: The aim of this study was to investigate the effects of different mechanical surface treatment methods on the transverse strength of a repaired conventional heat-polymerized acrylic resin.

Materials and Method: One hundred and sixty rectangular-shaped acrylic resin specimens were prepared using a custom mold, and divided into 4 groups according to different surface treatment methods; Group 1 (control): no treatment, Group 2: air-borne particle abrasion, Group 3: plasma application, and Group 4: Er:YAG laser application. Following the surface treatments, the repaired surfaces were examined using Scanning Electron Microscopy (SEM) and Energy Dispersion Spectroscopy (EDS). Then, the specimens were repaired with autopolymerizing acrylic resin to form a total of 80 (n=20/group) rectangular-shaped (65×10×3.3 mm) test specimens. The repaired specimens were subjected to thermal cycling. Then, the transverse strength was measured by a three-point bending test using a universal testing machine. The data were analyzed by using one-way ANOVA and Tukey HSD tests. The results were considered significant for α=0.05.

Results: Group 2 (27.06 ± 5.02 MPa) and Group 4 (26.06 ± 3.44 MPa) revealed significantly greater transverse strength values compared to the control (Group 1; 18.26 ± 5.27 MPa), and Group 3 (11.19 ± 2.73 MPa) (p<0.05), Group 3 revealed significantly lower transverse strength values compared to all other groups (p<0.05).

Conclusion: Air-borne particle abrasion or Er:YAG laser application increased the transverse strength of heat-cure acrylic resin repaired with autopolymerizing acrylic resin; however, the plasma treatment decreased the transverse strength.
