Abstract

Purpose: The objective of this study was to evaluate the augmentation volume needed for different sinus lift levels (from 10 mm to 18 mm) with 3D CT, and software. Material and Methods: Data from 15 CTscans was obtained from 15 adult patients (ten male/ five female) for the purposes of this study. The CT data, in DICOM format, was read into Mimics software from Materialize (Leuven, Belgium), with a slice thickness of 0.5 mm. Different levels of sinus lift augmentation (from 10 mm to 18 mm) volume were calculated on the 3D images using Mimics software. Results: The average calculated augmentation volume for an augmentation height of 10 mm was 1665.49 ± 657.18 mm3 and needed amount of graft was 2.32 cm3 ; for an augmentation height of 18 mm, the average volume required was 5057.73 ± 1619.36 mm3 and needed amount of graft was 6.67 cm3. Conclusion: Using three-dimensional computerized tomography (3D CT) technique, to determine preoperative knowledge of the sinus lift augmentation volume and needed amount of graft material would be increase long-term success of surgery operation and implants.

SİNÜS TABANI YÜKSELTİLMESİ İÇİN GEREKLİ GRAFT HACMİNİN ÜÇ BOYUTLU BİLGİSAYARLI TOMOGRAFİ YÖNTEMİ İLE DEĞERLENDİRİLMESİ

Abstract

Amaç: Bu çalışmanın amacı farklı seviyelerdeki sinüs tabanı yükseltmelerinde gerekli olan greft ihtiyacını üç boyutlu bilgisayarlı tomografi (3B-BT) ve yazılım yardımıyla değerlendirmekti. Materyal ve Method:Bu çalışmada 15 erişkin hastadan (10 erkek/5 bayan) alınan bilgisayarlı tomografi dataları kullanıldı. Dicom formatında, 0.5 mm kesit kalınlığındaki BT dataları Materiliase (Leuven, Belçika) firmasının Mimics adı verilen yazılımına aktarıldı. Sinüs tabanının farklı seviyelerde (10 mm’den -18 mm) yükseltilmesi için gerekli hacim 3B-BT görüntüleri ve mimics yazılımı kullanılarak hesaplandı. Bulgular: 10 mm agmentasyon yüksekliği için gerekli agmentasyon hacmi 1665.49 ± 657.18 mm3 ve gerekli greft miktarı ise standart sapmalar da dikkate alındığında yaklaşık olarak 2.32 cm3 olarak hesaplanırken, 18 mm agmentasyon yüksekliği için gerekli agmentasyon hacmi 5057.73 ± 1619.36 mm3 gerekli greft miktarı ise 6.67 cm3 olarak hesaplandı. Sonuç: Üç boyutlu bilgisayarlı tomografi (3BBT) tekniği kullanılarak operasyon öncesi sinüs agmentasyonu için gerekli hacmi ve kullanılacak greft materyali miktarının belirlenmesi, cerrahi müdahalenin ve yerleştirilecek implantların uzun dönem başarısını olumlu yönde arttıracaktır.
