Abstract

ABSTRACT
Objective: The aim of this study was to evaluate the effect of dental technicians’ experience on the shear bond strength (SBS) of ceramic fused to metal restorations.
Methods: Totally 32 casting cobalt–chromium (Co-Cr) disc-shaped (r = 10 mm diameter, h = 1 mm height) specimens were prepared for 2 experimental groups [group 1: untrained dental technician, group 2: conversant dental technician] (n = 16 per group). Ceramic was applied to the disc speci- mens (h = 4 mm height, r = 6 mm diameter), and their SBS was measured with a universal testing device. Results were statistically analyzed using the Student’s t-test (α = .05).
Results: According to the Student’s t-test, no statistically significant differences were seen between the 2 groups (P = .270).
Conclusion: The experience of the dental technicians did not affect the bond strength of casting Cr-Co alloys.
Keywords: Experience, technician, metal–ceramic bonding

ÖZ
Amaç: Bu çalışmanın amacı teknisyen deneyiminin metal destekli seramik restorasyonların makas- lama bağlanma direncine (shear bond strength-SBS) etkisinin olup olmadığının araştırılmasıdır.
Yöntemler: 32 tane döküm Co-Cr disk (10 mm çapında, 1mm kalınlığında) şeklinde örnek iki ayrı çalışma grubu [Grup 1: Deneyimsiz diş teknisyeni (Untrained dental technician-UDT), Grup 2: Deneyimli diş teknisyeni (Conversant dental technician-CDT)] (n = 16 her bir grup için) hazırlandı. Örneklere seramik uygulaması (4 mm yüksekliğinde, 6 mm çapında) yapıldı ve SBS üniversal bir test cihazı ile ölçüldü. Sonuçlar istatistiksel olarak Student t-test ile analiz edildi (α = .05). Bulgular: Deney grupları arasında istatistiksel olarak anlamlı bir sonuç bulunmamıştır (P =.270).
Sonuç: Diş teknisyeninin deneyimli olup olmamasının döküm Co-Cr alaşımlarının bağlanma direncine etkisi görülmemiştir.
Anahtar kelimeler: Deneyim, teknisyen, metal-seramik bağlanması
