AbstractWith the introduction of cone beam computed tomography (CBCT) into dentistry in the 1990s, radiologists have become more frequently involved in dental implant planning. This article describes the information that should be included in a radiology report to achieve a successful implantation. The justification to use CBCT during the preoperative planning phase is based on the need to evaluate patient-specific anatomy in detail (general condition of the jaw, bone quantity, and bone quality), the application of more advanced surgical techniques (maxillary sinus augmentation procedure, zygomatic implants), and the integrated presurgical planning and virtual patient approach. Postoperatively, CBCT is used when implant retrieval is anticipated and two-dimensional radiographs have not provided sufficient information, for evaluation of graft healing, or to assess complications, mostly related to neurovascular trauma.

With the evolution of implant dentistry, immediate implantation remains a challenge especially in achieving a good primary stability with avoidance of complications such as nerve injuries and lingual perforations. This study was aimed to determine the risks of nerve injury and lingual perforation following virtual implant placement at mandibular canines, mandibular first premolars and mandibular second premolars using cone beam computed tomography (CBCT) scans. From the total of 771 CBCT scans screened, 100 CBCT scans were included. Measurements were made based on the cross-section of the study teeth, that were mandibular canine, first premolar and second premolar, to obtain the distance between root apex and nerve canal as well as risk of nerve injury. A virtual implant was then placed at each site to assess the risk of lingual perforation. Generally, the distance between root apex and nerve was less than 6 mm and the highest risk of nerve injury was observed at second premolar (79.6%) followed by first premolar (45.3%) and canine (23.4%). Risk of lingual perforation following immediate implant placement was between 0.7-1.5%. The risk of nerve injury was considerably high due to insufficient root apex to nerve canal distance while the risk of lingual perforation was low.

Objective: To evaluate the relationship between bone density measured by computed tomography (CT) and cone beam computed tomography (CBCT) (Sirona’s Galileos scanner) with primary stability of dental implants. Material and methods: 20 fresh bovine femoral heads were prepared by removal of soft tissue, sectioning of the bone, and placement of markers for location and angulation of implants. Bone density of peri-implant areas was determined preoperatively by CT and CBCT scanning of the prepared bone samples represented by Hounsfield units (HUs) and gray values (GVs), respectively. Then, 60 implants in three sizes (diameter = 4 mm, length = 8, 10, and 12 mm) were inserted into the bones and maximum insertion torque (IT) was recorded. Osstell device was also used for determining the implant stability quotient (ISQ) for each implant. Statistical analysis was performed on the data (alpha = 0.05). Results: Mean ± SD values of GV, HU, and ISQ were 1592.75 ± 231.82, 675.26 ± 115.38 and 61.90 ± 10.14, respectively. Moreover, the most frequent IT limit was 30-35 Ncm (41.4%). Significant relationships were observed between HU and IT, GV and IT, HU and ISQ, GV and ISQ, and IT and ISQ in all implant sizes. Moreover, GV and HU also significantly correlated to each other. Conclusion: Bone density values in CBCT and CT scans are positively associated to primary stability of dental implants. Therefore, GVs obtained from Galileos CBCT scanner can be used for preoperative selection of edentulous sites which allow for better implant stability or locations which require further procedures for enhancing the success rate of dental implants.  KEYWORDSComputed tomography; Cone beam computed tomography; Dental implant.

In this article, we evaluate the effectiveness of Cone Beam Computed Tomography, through a case study, in assessing the complication of intracranial bleeding during an endovascular treatment of brain arteriovenous malformation when compared to Multislice-Detector Computed Tomography performed immediately after the procedure. The image quality of Cone Beam Computed Tomography has enough diagnostic value in differentiating between haemorrhage, embolic materials and the arteriovenous malformation nidus to facilitate physicians to decide for further management of the patient.
