ABSTRACT
 Objective: Width, height, density and morphology of alveolar bone must be carefully examined before the surgical intervention for a successful implant treatment. The panoramic radiography (OPG) is the most frequently used method that is employed by large majority of dentists in dental implant planning. The purpose of this study is, to evaluate the consistency of OPG and cone beam computed tomography (CBCT) alveolar height measurements at different recipient sites in dental implant planning. Material and Methods: The present study was carried out on the OPG and CBCT images of 206 patients. Using the radiological data of subjects, 752 edentulous implant sites were specified. These areas were classified into 3 groups based on the proximity to certain anatomical landmarks, which were 'maxillary sinus (MS)', 'mental foramen (MF)' and 'nasal floor (NF)'. Bone distances between anatomical points and alveolar crest were measured on the OPG and CBCT cross-sectional images. Results: In MS group, the correlation between OPG and CBCT was 0.968 (p<0.001). The correlation between OPG and CBCT was 0.860 in MS-II subgroup (p<0.001). The correlation between OPG and CBCT was 0.950 in MF-I subgroup (p<0.001) and 0.932 in MF-II subgroup (p<0.001). The correlation between OPG and CBCT was 0.965 in NF group (p<0.001). Conclusion: OPG is a safe method in measuring the vertical bone distance on maxillary sinus region for implant planning. However, it might not be safely used on the mental foramen and nasal floor regions.

Keywords: Dental implants; CBCT (Cone-Beam Computed Tomography); panoramic radiography
ÖZET
 Amaç: İmplant cerrahisi öncesi alveolar kemiğin genişliği, boyu ve yoğunluğu dikkatli bir şekilde değerlendirilmelidir. Diş hekimlerinin büyük çoğunluğu implant planlamasında panoromik radyografileri (OPG) kullanmaktadır. Bu çalışmanın amacı dental implant planlamasında farklı alıcı bölgelerin boyutunun değerlendirilmesinde OPG ve konik ışınlı volumetric tomografi (KIVT) arasındaki uyumun değerlendirilmesidir. Gereç ve Yöntemler: Bu çalışmada 206 hastanın OPG ve KIVT görüntüleri kullanılmıştır. Radyolojik arşivinden, 752 dişsiz implant bölgesi çalışma için seçilmiştir. Bu alanlar ilgili anatomik bölgelere yakınlığına göre maksiller sinus (MS), mental foramen (MF) ve nasal taban (NT) olarak üç gruba ayrılmıştır. Anatomik noktalar ile alveolar kret arası mesafe OPG ve KIVT üzerinde ölçülmüştür. Bulgular: MS grubunda OPG ve KIVT arasındaki korelasyon 0,968 olarak bulunmuştur (p<0,001). MS-II alt grubunda ise OPG ve KIVT arasındaki korelasyon 0,860 olarak bulunmuştur (p<0,001). MF I ve II grubunda ise OPG ve KIVT arasındaki korelasyon sırasıyla 0,950 ve 0,932 olarak bulunmuştur (p<0,001). NF grubunda OPG ve KIVT arasındaki korelasyon 0,965 olarak bulunmuştur (p<0,001). Sonuç: MS bölgesinde implant planlamasında OPG tek başına güvenle kullanılabillir. Ancak, MF ve NT bölgesinde sadece OPG ile ölçüm yapılması güvenli olmayabilir.
