Elastomerik Ölçü Materyallerinde Güncel Gelişmeler

Ölçü alma, daimi modelin doğruluğunu ve yapılacak restorasyonun pasif uyumunu doğrudan etkilediği için protetik tedavi sürecinde önemli bir aşamayı oluşturur. Günümüzde sabit protetik tedavide ölçü alma işleminde elastomerik ölçü materyalleri olarak sıklıkla silikonlar C-silikon ve A-silikon ve polieterler kullanılmaktadır. Güncel olarak yeni geliştirilen vinilsiloksaneter elastomerik ölçü materyali, polieter ve polivinilsiloksan ölçü materyallerinin üstün özelliklerini bir arada bulundurmaktadır. Ancak bu ölçü maddesi ile ilgili araştırmalar halen devam etmektedir. Ölçü alma işlemi için günümüzde geleneksel ölçü tekniğinin yanı sıra bilgisayar destekli tasarım ve üretim sistemlerindeki gelişmelerle birlikte dijital ölçü tekniğinin kullanımı yaygınlaşmıştır. Ölçülerin dijital olarak alınması ve ağız içi ince detayların tarayıcı yardımıyla kaydedilebilmesine rağmen, bilgilerin hastadan laboratuvara aktarılmasında geleneksel ölçü yöntemlerinin hala önemli bir rolü vardır. Ölçü materyallerindeki ilerleme teknoloji ve materyallerin gelişmesiyle devam etmektedir. Eldeki her materyal ve teknik, hangisinin en iyi performansı sunacağını belirlemek için dikkatlice değerlendirilmelidir

Actual Developments in Elastomeric Impression Materials

Taking impression is an important step for accuracy of the master model and passive fit of restorations at prosthetic treatment. Nowadays; condensation silicones, addition silicones and polyethers are used for fixed prosthetic treatments. Polyvinyl siloxane impression material is a new material that has superior characteristics of both polyether and polyvinyl siloxane but researchs on this material are ongoing. Developments on computer aided design and manufacturing systems make digital impressions become prevelant besides conventional impression techniques. Although digital impressions can record intraoral details from patients, conventional impression techniques still have important roles for transferring data from patient to the laboratory. Developments on technology and materials affect impression materials and techniques in addition to this improvements are still continuing. Available materials and techniques must be evaluated carefully to determine which material have the best performance for usage
