“…The image is largely affected by the body position with variable magnification rates and distortion rates for different parts [ 19 , 20 ]. Previously, panoramic radiography is shown to be a sufficiently accurate method to obtain the interatral bone height in the incisor area, but not in the canine area as compared with CBCT [ 21 ].…”

BackgroundCone beam computerized tomography (CBCT) has been widely used in dental implanting. However, the local hospitals usually don’t have access to CBCT due to the cost and medical investment, especially in West of China. The doctors in local hospitals have to make reasonable dental planting using orthopantomography (OPG) to reduce risks. Therefore, it is clinically meaningful to determine the magnification rate of OPG to obtain correct diagnosis. This study investigated the magnification rate of OPG in measuring different maxillofacial loci compared with CBCT.MethodsEighty-six patients demanding dental implanting were scanned by CBCT and OPG. The vertical distance between the alveolar ridge crest of the maxillary first molar and the sinus bottom of the upper jaw, the distance between the alveolar ridge crest of the mandibular first molars and the top of nerviduct in the mandibular alveolar, and the distance between the alveolar ridge crest of the maxillary central incisors and the bottoms of the nasal cavities were measured. The horizontal distance in those loci were also measured. The distances derived from CBCT were used as reference. The distances between the two methods were compared using paired t-test. The magnification rates at these positions were calculated. The relationship between the data acquired from the two methods was analyzed Pearson correlation.ResultsThe correlation coefficients (R) between the paired samples obtained from OPG and CBCT were highly related (P < 0.05) with R values varying from 0.840 and 0.959 in vertical distances and R values varying from 0.703 and 0.904 in horizontal distances. Compared with data obtained from CBCT, the mean vertical magnification rates were 11.38% and 12.95% vertically and 8.55% and 9.43% horizontally for the first molars in the right and left maxilla respectively; 7.26% and 6.35% vertically and 5.33% and 4.96% horizontally for the first molars in the right and left mandible respectively; and 5.55% and 4.84% vertically and 6.53% and 7.47% horizontally for the central incisors in the upper right and left jaws respectively.ConclusionThe magnification rates of OPG at these teeth are different. The distances measured by OPG were highly correlated with that measured by CBCT.

“…25 Kopecka et al reported that, OPG doesn't give accurate results in alveolar bone height measurements in the maxillary canine region when compared to CBCT. 26 They concluded that it offers more consistent results with CBCT in maxillary incisor region. In the present study, we also found a weak correlation between two methods in NF group.…”

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.

“…Radiography is carried out for evaluating the quantity and morphology of the remaining peri-implant alveolar bone and its surrounding anatomical structures, especially the position of the IAN and the maxillary sinus. (14,15) Some studies have assessed the IAN damage after placing an implant in the mandibular bone. (16-26) Lin et al studied the IAN damage during immediate implantation.…”

“…The patients (n=100) included 43 women and 57 men, averagely 53 years old, who experienced neurosensory changes 10 days after implantation, and panoramic radiographs (CRANEX® D Panoramic Dental X-Ray Machine, Soredex, Orion Co. Ltd., Helsinki, Finland) were taken as soon as they reported the neural changes. (14)(15)(16) The purpose of the study was explained to the patients, and written informed consent forms were received.…”

ARTICLE INFOBackground and aim: Neurosensory disorders after implant insertion are one of the main concerns in implant treatments. Neurosensory disorders can be driven by different factors including the contact of the implant with the nerve, pressure of edema, hematoma, scar, or dental injections. This study aimed at investigating the distance between the implant and the inferior alveolar nerve (IAN) and its impact on neurosensory disorders. Materials and methods:In this descriptive study, panoramic radiographs were taken from 100 patients experiencing neurosensory changes after 10 days of implantation. The patients were reassessed 4 weeks later, and the distance (mm) between the implants and the IAN was measured. Data were analyzed using descriptive statistics. Results: All patients experienced neurosensory changes 10 days after implantation.Four weeks after surgery, 82 patients healed: the distance between the implants and the IAN was 1-2 mm in 16 patients and 2 mm in 66 patients. In 18 patients, neurosensory changes persisted; in this group, the distance between the implants and the IAN was less than 1 mm in 11 patients, 1-2 mm in 6 patients, and more than 2 mm in 1 patient. The results indicated that the chance of healing of neurosensory changes is significantly correlated with the distance between the implant and the IAN (P<0.01). This correlation was not significant with respect to age or gender (P<0.9). Conclusion: It seems that the lesser is the distance between the implant and the IAN, the lower is the chance of healing of neurosensory changes.
