Cone‐beam computed tomography of the maxillofacial region—an update

Abstract

3D imaging is developing at a very fast pace. New technologies and machines are emerging and CBCT is becoming readily available. Due to the growing demand for the technology based on the needs of clinicians, there is now a wide and growing selection of devices on the market. Some of the new advances now mean that CBCT imaging should be a well-considered option in maxillofacial imaging.

The Indications for Dental Volumetric Tomography in a Turkish Population Sample

“…[24][25][26] DVT'nin BT'ye göre daha küçük kesit kalınlığı ile görüntülerin elde edilmesine olanak sağlaması, daha kısa sürede, gerçek boyutta ve yüksek çözünürlükte görüntüler elde edilmesi, 20,26 hastanın maruz kaldığı radyasyon miktarının da BT cihazlarından yaklaşık 15-20 kat daha az olması gibi önemli üstünlükleri olduğu bilinmektedir. 20,[27][28][29] 38 Sinüs radyografisinde kullanılan konvansiyonel radyografilerin; ideal hasta pozisyonunu sağlamada güçlük, diğer anatomik yapıların süper-pozisyonu ve yumuşak ve sert doku patolojilerinin tespitindeki zorluklar gibi dezavantajları vardır. 39 Maksillofasiyal bölgenin sert dokularını görüntülemek için tasarlanmış olan DVT, BT' ye göre daha düşük doz ve daha az maliyet avantajına sahiptir.…”

Influence of cone beam CT scanning parameters on grey value measurements at an implant site

“…[16][17][18][19][20] However, the manufacturers of CBCT devices use different approaches for setting exposure factors. 21 Since there should be a balance between the diagnostic value of the scanned volume and the exposure risk to the patient, there is a real need to select ideal exposure settings in order to optimize image quality and to lower radiation dose. 22,23 For example, it has been shown that reducing the number of projections results in a significant reduction in patient radiation exposure while not necessarily leading to reduced dimensional accuracy, 24 and that a rotation of 180°is recommended to lower the scan time and radiation dose, especially in implant planning for the lower jaw.…”

Accuracy of CBCT Measurements of a Human Skull

“…CBCT is now commonly used for a variety of purposes in implantology, dentomaxillofacial surgery, image-guided surgical procedures, orthodontics, periodontics, and endodontics [1,2]. Recently, the use of digital CBCT models has come to replace traditional dental casts in diagnosis, treatment planning, and simulation [3].…”
