Objective: The aim of this study was to evaluate of the dimensional accuracy of Polyvinylsiloxane (PVS) impression materials (Spirias, Imicryl, Konya, Turkey and Variotime, Heraeus, Hanau, Germany) by using stone models after different pouring time (1 hour and 24 hours).
Methods: A standard maxillary dentulous acrylic model was selected as master model. Two linear measurements were selected on each sample for the evaluation of the models (x: 13-23 distance, y: 13-26 distance). A total of 40 samples were divided into 4 groups according to the impression brands and pouring time (n=10). All of measurements were made with CEREC SW 4.2.3 software (Sirona Dental System, GmbH, Bensheim, Germany) using “distance” tools of the programme. Statistical analysis was performed by using the IBM SPSS Statistics, Version 25 (IBM SPSS Statistics for Windows, IBM Corporation, Armonk, NY). A value of p<0.05 was considered statistically significant.
Results: The relationship between different pouring times (1 hour and 24 hours) was not statistically significant (p>0.05). When the paired relations with the master model are evaluated, t test and p values show that there is statistically significant difference (p<0.05).
Conclusion: When compared with the main model, PVS materials for both brands show dimensional distortion. For PVS impression materials, the pouring of the impressions does not make any difference.

Amaç: Bu çalışmanın amacı, Polivinilsiloksan (PVS) ölçü malzemelerinin (Spirias, Imicryl, Konya, Türkiye ve Variotime, Heraeus, Hanau, Almanya) farklı döküm sürelerinden sonra (1 saat ve 24 saat) alçı modeller kullanılarak boyutsal doğruluğunun değerlendirilmesidir.
Yöntem: Ana model olarak standart maksiller akrilik model seçildi. Modellerin değerlendirilmesi için her numune üzerinde x ve y mesafesi adıyla iki lineer ölçüm noktası belirlendi (x: 13-23 nolu dişler arası mesafe, y: 13-26 nolu dişler arası mesafe). Ölçü markalarına ve dökme süresine göre toplam 40 örnek 4 gruba ayrıldı (n=10). Tüm ölçümler “mesafe” araçları kullanılarak CEREC SW 4.2.3 (Sirona Dental System, GmbH, Bensheim, Germany) yazılımı ile yapıldı. İstatistiksel analiz, IBM SPSS Statistics, Sürüm 25 (Windows için IBM SPSS Statistics, IBM Corporation, Armonk, NY) kullanılarak gerçekleştirildi. p<0,05 değeri istatistiksel olarak anlamlı kabul edilmiştir.
Bulgular: Farklı dökme süreleri (1 saat ve 24 saat) arasındaki ilişki istatistiksel olarak anlamlı bulunamamıştır (p>0,05). Ana model ile eşleştirilmiş markaların ilişkileri değerlendiriliğinde, t testi ve p değerleri istatistiksel olarak anlamlı bir fark olduğu gösterilmiştir (p<0,05).
Sonuç: Ana modelle karşılaştırıldığında, her iki marka için PVS malzemeleri boyutsal değişim göstermektedir. Ancak bu değişim PVS ölçü malzemeleri için, alçı modellerin dökülme süreleri arasında herhangi bir fark yaratmamaktadır.
