Abstract
Amaç: Bu çalışmanın amacı, dişsiz üst çene arkına yerleştirilen 5 implantın kapalı ölçü kaşığıyla alınan ölçülerde ölçü maddesinin ölçü doğruluğuna etkisini değerlendirmektir.
Materyal ve Metod: Dişsiz üst çene arkı ve ölçü kaşıkları otopolimerizan akrilik reçineden üretilmiştir. İmplantları temsil eden analoglar dişsiz üst çene modelinde orta hatta, her iki tarafta kanin bölgesine ve birinci molar bölgelerine yerleştirilmiştir. Çalışma 4 gruptan oluşmaktadır (n=10). Çalışma grupları şu şekildedir: grup C1 polivinil siloksan (Elite HD+ Tepsi Malzemesi; Zhermack İtalya); C2 polivinil siloksan (Hydrorise Implant Heavy&Light NS; Zhermack, İtalya); C3 kondensasyon silikonu (Zetaplus Putty ve Oranwash L; Zhermack, İtalya) ve C4 polieter (3M ESPE (Soft) Monophase, ABD). Geleneksel ölçüler bu çalışma için hazırlanan bireysel kaşıklarla alınmış ve tip4 alçıdan modeller elde edilmiştir. Bu modeller laboratuvar tipi tarayıcıyla taranmış ve ölçümler yapılmıştır. Ölçümler SPSS 27 programı kullanılarak tek yönlü ANOVA analizine tabi tutulmuştur (p=0,05).
Bulgular: Tek yönlü ANOVA analizine göre sıfır hipotezi reddedilmiştir yani gruplar birbirinden farklı bulunmuştur. %99,2 anlamlılık düzeyinde Grup 4’ün diğer gruplardan farklı özelliklere sahip olduğu belirlenmiştir.
Sonuç: Polivinil siloksan ölçü malzemesi, implant destekli protezlerin ölçüleri için güvenilir sonuçlar sağlar. Sertlik ve polimerizasyon büzülmesinin polieter ölçü malzemesinin doğruluğunu azalttığı düşünülmektedir.
Ethical Statement
“Tam Dişsiz Hastaların İmplantüstü Protezlerle Rehabilitasyonunda Kullanılan Geleneksel Ölçü Maddelerinin Boyutsal Stabilitesinin Değerlendirilmesi” (Dimensional Accuracy of Conventional Impression Materials on Full-Arch Implant Impression) başlıklı çalışmamız kapsamında gerçekleştirdiğimiz literatür taraması, insan ve hayvan sağlığı üzerinde herhangi bir risk oluşturmadığı ve sadece model üzerinde gerçekleştirilen bir çalışma olarak mevzuata uygun olarak yapıldığı için etik kurul iznine gerek duyulmamaktadır.Çalışmamız, herhangi bir kişi üzerinde deneysel bir müdahale içermemektedir. Bu bağlamda, çalışmanın etik kurul gerekliliği olmadığı kanaatindeyiz.

Abstract
Objective
The purpose of this in vitro study was to compare conventional impression materials for close tray implant impressions of maxillary full arch with 5 implants.
Material and Method
The edentulous maxilla model and custom impression trays were fabricated from auto-polymerizing acrylic resin. 5 implant analogs (Moment Dental Implant Systems, Turkey) representing implants were placed in the midline on the edentulous maxilla model, on both sides canine and first molar region. The study consisted of 4 groups(n=10). Study groups were as follows: group C1 polyvinyl siloxane (Elite HD+ Tray Material; Zhermack Italy); C2 polyvinyl siloxane (Hydrorise Implant Heavy&Light NS; Zhermack, Italy); C3 condensation silicone (Zetaplus Putty and Oranwash L; Zhermack, Italy) and C4 polyether (3M ESPE (Soft) Monophase, USA). Conventional impressions were performed with custom-made close trays and casts were made by type IV dental stone. Casts were scanned with the laboratory-type scanner. Whether the data of four separate groups showed a normal distribution was analyzed at the significance level (p = 0.05) using one-way ANOVA analysis using the SPSS 27 program.
Results
According to one-way ANOVA analysis, the null hypothesis was rejected because the significant value was greater than 0.05, meaning one of the groups was different from the other. At the 99.2% significance level, it was determined that Group 4 had different characteristics from the other groups.
Conclusion
Polyvinyl siloxane impression material provides reliable results for impressions of implant-supported prostheses. Rigidity and polymerization shrinkage are thought to reduce the accuracy of polyether impression material.
