Abstract

Aim: The purpose of this study is to compare the linear measurements with the digital measurements on dental casts and to demonstrate the effectiveness of the computer-aided 3-dimensional measurement method. Material and Methods: An arc-shaped master model consisting of 5 prepared teeth (right-left first molars, right-left canines and one incisor) was designed with computer-aided design and fabricated with CoCr alloy powder using computer-aided manufacturing (CAD/CAM) technology. A total of 10 impressions were made with vinyl siloxanether (VSE) impression material from the master model. The master model and definitive casts were digitized with an optical extraoral scanner. Measurements on definitive casts (VSE Manuel) were made with digital micrometer and measurements on digitized casts (VSE Digital) with 3-dimensional (3D) analysis software. In addition, model analyzes were done with the same software and color-coded maps were created. Differences were analyzed using univariate analysis of variance and post hoc tests were used for multiple comparisons. Results: Statistically significant differences were found between VSE Manuel and Digital groups (p

Özet

Amaç: Bu çalışmanın amacı, dental alçı modeller üzerindeyapılan manuel ve dijital lineer ölçümleri karşılaştırmak vebilgisayar destekli 3 boyutlu ölçüm yönteminin etkinliğinigöstermektir.Materyal ve Metod: Üzerinde 5 adet prepare edilmiş dişbulunan (sağ-sol I. molarlar, sağ-sol kaninler ve 1 keisicidiş) mandibulayı temsil eden ark şeklinde bir ana model,bilgisayar destekli tasarım ile tasarlanmış ve bilgisayardestekli üretim (CAD/CAM) teknolojisi ile CoCr alaşımtozundan üretilmiştir. Ana modelden vinil siloksan eter(VSE) ile ölçü alınmış ve toplamda 10 alçı model eldeedilmiştir. Ana model ve çalışma modelleri optik ekstraoraltarayıcı ile dijitalleştirilmiştir. Alçı çalışma modelleriüzerindeki manuel lineer ölçümler (VSE Manuel) dijitalkumpas ile dijital modeller üzerindeki lineer ölçümler (VSEDijital) ise 3 boyutlu (3D) analiz yazılımı ile yapılmıştır.Ayrıca çalışma modelleri üzerinde 3D analizler de yineaynı yazılım ile yapılmış ve renk kodlu haritalaroluşturulmuştur. Tek değişkenli varyans analizikullanılarak farklılıklar analiz edilmiş ve çoklukarşılaştırmalar için post hoc testleri kullanılmıştır.Bulgular: VSE Manuel ve Dijital grupları arasındaistatistiksel olarak anlamlı farklılıklar bulunmuştur(p
