Abstract

Statement of the Problem: Accurate measurement of the Available bone height is an essential step in the pre-surgical phase of Dental implantation. Panoramic radiography is a unique technique in the pre-surgical phase of Dental implantations because of its low cost, relatively low-dose, and availability. Purpose: This article aimed to assess the reliability of Dental panoramic radiographs in the accurate measurement of the vertical bone height with respect to the horizontal location of the alveolar crest. Materials and Method: 132 Cone-beam computed tomography (CBCT) of the edentulous mandibular molar area and Dental panoramic radiograph of 508 patients were selected. Exclusion criteria were bone abnormalities and detectable ideal information on each modality. The alveolar ridge morphology was categorized into 7 types according to the relative horizontal location of the alveolar crest to the mandibular canal based on CBCT findings. The Available bone height (ABH) was defined as the distance between the upper border of the mandibular canal and alveolar crest. One oral radiologist and one oral surgeon measured the Available bone height twice on each modality with a 7-dayinterval. Results: We found a significant correlation between Dental panoramic radiographs and Cone-beam computed tomography values (ICC=0. 992, p< 0. 001). A positive correlation between the horizontal distance of the alveolar crest to the mandibular canal and measured differences between two radiographic modalities had been found (r=0. 755, p< 0. 001). For each single unit of increase in the horizontal distance of the alveolar crest to the mandibular canal, Dental panoramic radiographs showed 0. 87 unit of overestimation (p< 0. 001). Conclusion: Dental panoramic radiographs can be employed safely in the pre-surgical phase of Dental implantation in posterior alveolus of mandible, especially in routine and simple cases.
