“…Furthermore, for many other surgical procedures, the overall dimension of the mandible is crucial. This is the case in the removal of wisdom teeth, in the application of buccal mini screws for orthodontic anchorage and of course in orthognathic surgery [25][26][27]. Therefore, this study used CBCTs to assess the intraosseous course of the IAN, the bone thickness between the lateral wall of the mandibular canal and the buccal border of the mandibular cortical plate and the position of the mental foramen in relation to the neighbouring teeth.…”

Background: The aim of this study was to assess vestibular bone thickness of the mandible in relation to the mandibular canal and position of the mental foramen in relation to the neighbouring teeth. Measurements were performed on radiographic cone-beam computed tomography (CBCT) images. Methods: This retrospective study analysed 314 CBCTs, having been taken at the Clinic of Cranio-Maxillofacial and

“…8 The investigation of bone anatomy is important in many branches of Dentistry, influencing surgical planning, 6,9 dental implant rehabilitation outcome, 10 and selection of the best positioning for skeletal anchorage, which improves orthodontic mechanics. 11 However, information regarding bone thickness in the apical region of maxillary and mandibular teeth is scarce, though very important for endodontic purposes, specially for the surgical planning in paraendodontic surgery.…”

CBCT assessment of bone thickness in maxillary and mandibular teeth: an anatomic study The site of the sinus tract depends on the rate of resistance against abscess exudate drainage, bone morphology, and distance from the root apex to the outer cortical bone. Objective: To assess apical bone thickness in buccal and palatal/lingual aspects of maxillary and mandibular teeth, using a high-resolution cone-beam computed tomography (CBCT) system. Methodology: In total, 422 CBCT examinations were included in the study, resulting in a sample of 1400 teeth. The scans were acquired by PreXion 3D, with a high-resolution protocol. The bone thickness was taken as the distance between the center of the apical foramen and the buccal and lingual/palatal cortical bone. The quantitative variables were expressed as mean values±standard deviation. The independent samples were analyzed using the t-test or the Mann-Whitney test (p<0.05). Results: The lowest mean value of bone thickness was observed in the buccal cortical bone of the upper canines (1.49 mm±0.86) and in the upper central incisors (1.59 mm±0.67). In premolar teeth, the lowest values were found in the buccal cortical bone of upper first premolars (1.13 mm±0.68). In the posterior teeth, the lowest values were found in the buccal cortical bone of upper first molars (1.98 mm±1.33). In the lower second molar region, the buccal cortical bone (8.36 mm±1.84) was thicker than the lingual cortical bone (2.95 mm±1.16) (p<0.05). Conclusions: The lowest mean values of bone thickness are in the buccal cortical bone of the maxillary teeth. In the mandible, bone thickness is thinner in the buccal bone around the anterior and premolar teeth, and in the lingual aspect of mandibular molars. All these anatomic characteristics could make the occurrence of the sinus tract more susceptible in these specific regions of the maxillary and mandibular alveolar bone.

Background The aim of this study is to evaluate through computed tomography differences in cortical plate thickness of condyle in patients with different facial vertical skeletal pattern.Methods The final sample of this retrospective study included CBCT exams of 60 adult subjects (mean age 33.2 ± 5.6), selected from the digital archive of a private practice. The subjects were assigned to 3 different groups according to the values of the Frankfurt-mandibular plane angle: hyper- normo- and hypodivergent group. The volume rendering of the mandible was obtained and three condylar points were marked on it: median pole, lateral pole and the most cranial point. For each considered reference point the minimum distance between external and internal cortical surface was measured, obtaining three different outcomes: median pole, lateral pole and cranial point cortical bone thickness. The measurement was executed by means of Mimics software by the same expert operator in specific scan views.Results The cortical bone thickness of hyperdivergent patients was found to be statistically thicker than normodivergent patients and hypodivergent patients. Cortical bone thickness of normodivergent patients was found thicker than hypodivergent patients. All the differences were statistically significant (p<0.05). The Person correlation coefficient showed a statistically significant correlation (p<.001) between the Frankfurt-mandibular plane angle and the evaluated cortical bone thickness outcomes.Conclusion Facial biotype characteristics that define vertical facial skeletal pattern affect the cortical bone thickness of mandibular condyle.
