Amaç: Çalışmamızda bilgisayarlı tomografi görüntülerinden elde edilen 3B (üç boyutlu) mandibula modeli üretiminde kullanılan parametrelerden alt eşik değişimi ve katman yüksekliğinin değiştirilmesinin model boyutu üzerindeki etkisi araştırılmıştır. Metod: 35 yaşında sağlıklı bir hastanın maksillofasiyal BT görüntüleri kullanılarak tasarlanan ve basılan 3B mandibula modelinin segmentasyon işleminde eşik değeri sırasıyla 200,175 ve 150 Hounsfield birimi (HU) alınarak modeller oluşturuldu. Oluşturulan modellerin polilaktik asit (PLA) filament malzemeden baskısında 0.1, 0.2 ve 0.3 mm baskı katman yüksekliği kullanıldı. Elde edilen modeller yüksek çözünürlüklü tarayıcı ile taranarak STL formatında dataları bilgisayara aktarıldı. Taranan modeller referans model ile karşılaştırılarak aralarındaki fark belirlendi. Deney tasarımı olarak Taguchi L9 ortogonal dizini kullanıldı. Taguchi metodunda referans model ile meydana gelen fark için en küçük en iyi sinyal gürültü oranı denklemi kullanıldı. Sonuç: Deneyler sonucunda iki faktör arasında farka en çok etkiyi eşik değerinin yaptığı gözlemlenmiştir. Ayrıca 3B yazıcı ile elde edilen mandibula modelleri ile BT’den elde edilmiş olan anatomik model karşılaştırmasında modellerin birbirine yakın olduğu gözlemlenmiştir.

Objective: In our study, the effect of changing the lower threshold and layer height on the model size from the parameters used in the production of 3D (three-dimensional) mandible model obtained from computed tomography images was investigated. Method: We used maxillofacial CT images of a 35-year-old healthy patient in the segmentation and printing process of 3D mandible model. In the segmentation process, the threshold value was used 200,175 and 150 Hounsfield units (HU), printing layer height was 0.1, 0.2, and 0.3 mm in the printing of the created models of polylactic acid (PLA) filament material. The obtained models were scanned with a high precision scanner. Their data in STL format were transferred to the computer, then scanned models were compared with the reference model, and the difference between them was determined. The Taguchi L9 orthogonal index was used as the experimental design. In the Taguchi method, the smallest best signal to noise ratio equation was used for the difference with the reference model Conclusion: As a result of the experiments, it was observed that the threshold value had the most effect on the difference between the two factors. Also, it was observed that in the comparison of the mandible models obtained with a 3D printer and the anatomical model obtained from CT, the models were similar.
