Dijital Ölçülerde Scan Body Tasarımının Tarama Hassasiyetine Etkisi
Özet
İmplant üstü protezlerde ölçü seansı kritik öneme sahiptir. Son yıllarda gelişen teknolojiyle beraber dijital ölçü alımı yaygınlaşmıştır. Final protezin pasif uyumu için dijital ölçülerde hassasiyet ve doğruluk kavramları öne çıkmaktadır. İntraoral tarayıcılarla birlikte kullanılan scan body tasarımlarının (geometri, boyut, materyal, bağlantı tipi) tarama hassasiyetine etkileri birçok çalışmada incelenmiştir. Geleneksel dikey scan bodylerin, özellikle tam dişsiz ark vakalarında referans noktası eksikliği nedeniyle yetersiz kalabildiği; buna karşılık yatay parçalara sahip yeni tasarımların tarama doğruluğunu ve tekrarlanabilirliğini arttırdığı, uygulayıcı kaynaklı hataları azalttığı literatür bulgularıyla desteklenmiştir. Mevcut çalışmalar, bu tasarımların özellikle tam ark dişsiz olgularda protez uyumunu iyileştirme potansiyeline sahip olduğunu ortaya koymakta ve klinik uygulamalarda yatay scan bodylerin kullanımını önermektedir.
