“…In this study, titanium pins were used since titanium has a low atomic number and hence, will cause very small metal artifacts. 9 , 10 Furthermore, the observers were allowed to change and adjust the contrast, sharpness, and gamma factor (which is among the features of the NNT viewer software) of the images, and by doing so, they could further minimize the metal artifacts.…”

PurposeThis study was performed to evaluate the effect of changing the orientation of a reconstructed image on the accuracy of linear measurements using cone-beam computed tomography (CBCT).Materials and MethodsForty-two titanium pins were inserted in seven dry sheep mandibles. The length of these pins was measured using a digital caliper with readability of 0.01 mm. Mandibles were radiographed using a CBCT device. When the CBCT images were reconstructed, the orientation of slices was adjusted to parallel (i.e., 0°), +10°, +12°, -12°, and -10° with respect to the occlusal plane. The length of the pins was measured by three radiologists, and the accuracy of these measurements was reported using descriptive statistics and one-way analysis of variance (ANOVA); p<0.05 was considered statistically significant.ResultsThe differences in radiographic measurements ranged from -0.64 to +0.06 at the orientation of -12°, -0.66 to -0.11 at -10°, -0.51 to +0.19 at 0°, -0.64 to +0.08 at +10°, and -0.64 to +0.1 at +12°. The mean absolute values of the errors were greater at negative orientations than at the parallel position or at positive orientations. The observers underestimated most of the variables by 0.5-0.1 mm (83.6%). In the second set of observations, the reproducibility at all orientations was greater than 0.9.ConclusionChanging the slice orientation in the range of -12° to +12° reduced the accuracy of linear measurements obtained using CBCT. However, the error value was smaller than 0.5 mm and was, therefore, clinically acceptable.

“…Although osseointegrated implants have achieved a considerable long‐term success, as evidenced by a recent American Academy of Osseointegration systematic review, the need for good pre‐implant cross‐sectional imaging has generally become to be viewed as essential for successful implants. When the bone height is inadequate for implants then grafts can be considered . Table shows that substantial literature on the value of CBCT to the implantologist is only recent: Hatcher and co‐workers first published on CBCT and implants in 2003 and, as Table demonstrates, this was soon followed by a deluge of publications.…”

“…Inadvertent injury to the mandibular canal and its neurovascular contents are minimized by CBCT, which allows accurate measurement to determine the safe depth of the implant. Excessive bleeding into the floor of the mouth is frequently occasioned by the tearing of the branches of the lingual artery during the implant surgery, as they run through the lingual canals . This is potentially life‐threatening.…”

“…Stents are now frequently made and provided by the dentist or prosthodontist prior to the CBCT exposure in order to ensure that the implants are placed precisely where they are required . This correct placement also minimizes the chance of the aforementioned complications arising from misplaced implants.…”

“…Other indications for CBCT are the presurgical assessment of unerupted teeth and intra‐osseous pathology, which on clinical examination and conventional dental radiography may have complicated relationships with adjacent teeth (unerupted maxillary canines and an intimate relationship with the apices of erupted incisors [Figure ]) or other structures (the mandibular canal, submandibular fossa, maxillary sinus, nasopalatine duct or branches of the lingual artery) …”

Although cone-beam computed tomography (CBCT) is just 15 years old, it has revolutionized the practice of dentistry, so much so, there is hardly a dental specialty which has not been affected by this technology. Nevertheless, it presents the dentist with a number of important challenges. An initial steep learning curve must be addressed without unnecessary exposure to the patient. This is particularly important when the patient is a child.
