“…Furthermore, the success rate did not differ by sex. Sumer et al (15) reported that palatal bone thickness, including that of cancellous bone, did not significantly differ between sexes. Moreover, Farnsworth et al (30) reported that palatal CBT did not differ between males and females.…”

“…Cortical bone quality and quantity are important factors in the primary stability of mini-screws, as such stability is achieved by mechanical retention rather than osseointegration (13)(14)(15). Nienkemper et al (16) found that orthodontic mini-screw stability depended mainly on mechanical maintenance, which should increase with insertion depth, because of the larger bone-to-implant contact area.…”

“…However, other studies have argued that dental CBCT is suitable for measuring cortical bone thickness. For example, Sumer et al concluded that CBCT is a suitable method for measuring the palatal cortical bone thickness at the implant site, and also argued that the feasibility of measuring the cortical bone thickness is determined by the image resolution rather than through methods such as conventional CT or dental CBCT. Tsutsumi et al stated that if the thickness of the measured cortical bone exceeds the voxel resolution of CBCT from threefold to fourfold, then CBCT would be suitable for measuring cortical bone thickness.…”

“…10 With the advent of 3D CBCT, the analysis of bone quality and quantity has greatly improved because it had low patient exposure as compared with computed tomography (CT) scan with high resolution. 11 A study conducted by Sumer et al 12 revealed that CBCT is the choice of diagnostic modality for measurement of palatal bone thickness at implant sites. Miyamoto et al 13 in their study used CT scan for analysis with a resolution of 400 μm, whereas in our study, the CBCT scans had a resolution of 100 μm.…”

Aim: Dental implants have emerged as a new treatment modality for the majority of patients complaining of missing teeth. Bone quantity and bone quality are among various factors which ensure the longevity of dental implant in the patient's mouth. The assessment of cortical bone thickness of the outer layer and the cancellous bone density by cone beam computed tomography (CBCT) has proved beneficial for the patient. This study aimed at presurgical measurement of crestal bone thickness at various implant sites using CBCT images. Materials and methods:This study was conducted in the Department of Prosthodontics in the year 2015. It included 218 patients who wanted to replace missing teeth. Patients were subjected to CBCT scan using NewTom CBCT machine operating at 120 kVp and 5 mA with a resolution of 0.1 × 0.1 × 0.1 mm 3 . New Net Technologies (NNT) software with a slice thickness of 0.1 mm was used in this study. A total of 780 implant sites were identified on images of 218 patients. In all patients, the measurement of crestal bone thickness in the region of implant site was performed with NNT software. The buccolingual measurement of crestal bone was done in cross sections obtained after CBCT. Results:Out of 218 patients, males were 110 and females were 108. The difference between gender was nonsignificant (p > 0.05). Out of 780 implant sites, 370 were in the maxilla and 410 were in mandible. The difference was nonsignificant (p > 0.05). Out of 780 implant sites, 210 were in anterior maxilla and 160 were in the posterior maxilla. Totally, 235 sites were in anterior mandible and 175 were in the posterior mandible. The distribution was nonsignificant (p = 0.15). The mean crestal bone thickness in anterior maxilla was 0.82 mm, in posterior maxilla was 0.76 mm, in anterior mandible was 1.08 mm, and in posterior mandible was 1.18 mm. The difference among regions was significant (p = 0.01). Measurement of Crestal Conclusion:The highest thickness of cortical bone was observed in posterior mandible followed by anterior mandible, anterior maxilla, and posterior maxilla. Thus, considering the less cortical thickness in the posterior maxillary region, the implant placement should be done with proper attention.Clinical significance: Dental implant is the need of the hour. It is beneficial to patients in terms of longer survival rates. With CBCT, all measurements, such as bone quality and quantity have become easy because of three-dimensional nature. This has proved to be beneficial in the analysis of cortical bone thickness as well as measuring the distance from anatomical structures.
