Üç Boyutlu Görüntüleme Yöntemleri ve Ortodontideki Kullanım Alanları
Özet
Ortodontik kayıtlar, tanı, tedavi planlaması ve vaka takibi için temel oluştururken, geleneksel 2D periapikal, panoramik ve sefalometrik radyografiler gömülü dişlerin konumu, kök rezorbsiyonları ve asimetri gibi karmaşık durumlarda yetersiz kalmaktadır. Son yirmi yılda gelişen üç boyutlu (3D) görüntüleme teknolojileri; Bilgisayarlı Tomografi (BT), Konik Işınlı Bilgisayarlı Tomografi (CBCT), Manyetik Rezonans Görüntüleme (MRG) ve Stereofotografi, diş ve çenelerin üç boyutlu analiz edilmesini sağlayarak zor vakalarda ayrıntılı teşhis bilgilerini kolaylaştırmaktadır. Medikal BT'ye kıyasla daha düşük radyasyon dozu, daha düşük maliyet ve yüksek çözünürlük sunan CBCT, ortodontide en çok tercih edilen 3D yöntemlerden biri haline gelmiştir; havayolu analizinde, gömülü dişlerin tespitinde ve temporomandibuler eklem (TME) patolojilerinin değerlendirilmesinde yaygın olarak kullanılır. MRG, radyasyon içermemesiyle TME ve üst solunum yolu analizinde avantaj sağlarken, stereofotografi ise cerrahi sonrası yüzün estetik değerlendirmesinde invaziv olmayan, radyasyonsuz bir alternatif sunar. Sonuç olarak, bu 3D teknolojiler geliştikçe veri depolama sorunları azalmakta ve multidisipliner iletişim güçlenmektedir.
This orthodontic record-keeping process forms the basis for diagnosis, treatment planning, and case follow-up, yet traditional 2D periapical, panoramic, and cephalometric radiographs remain insufficient in complex situations such as the positioning of impacted teeth, root resorptions, and asymmetry. Developing over the last two decades, three-dimensional (3D) imaging technologies—specifically Computed Tomography (CT), Cone-Beam Computed Tomography (CBCT), Magnetic Resonance Imaging (MRI), and Stereophotography—enable 3D analysis of teeth and jaws, facilitating detailed diagnostic information in challenging cases. Offering lower radiation doses, lower costs, and higher resolution compared to medical CT, CBCT has become one of the most preferred 3D methods in orthodontics; it is widely used in airway analysis, detection of impacted teeth, and evaluation of temporomandibular joint (TMJ) pathologies. While MRI provides advantages in TMJ and upper airway analysis due to its lack of radiation, stereophotography offers a non-invasive, radiation-free alternative for the aesthetic evaluation of the face after surgery. Consequently, as these 3D technologies advance, data storage issues decrease, and multidisciplinary communication strengthens.
