Cone beam computed tomographic evaluation of nutrient canals and foramina in the anterior region of the mandible

Abstract

The present study revealed the frequency and distribution of NCs using CBCT image analysis. NCs are important because surgical injury to the neurovascular bundle within these canals can lead to excessive bleeding and postoperative paresthesia. The identification of NC on CBCT images may be useful during the harvesting of bone blocks or placement of endosseous implants in the anterior region of the mandible.

Anatomical evaluation of the medial lingual foramen using cone-beam computed tomography: a retrospective study

“…The results showed that there was a relationship between foramen diameter and sex, with larger diameters found among male individuals than among female individuals. An MLF diameter between 1.0 mm and 3.2 mm has been reported elsewhere [17,20]. In our sample, foramina with a diameter greater than 1.0 mm were observed.…”

The Use of Cone‐Beam Computed Tomography in Management of Patients Requiring Dental Implants: An American Academy of Periodontology Best Evidence Review

“…Different studies have reported the importance of various neurovascular anatomic structures identified on cross‐sectional imaging, including: 1) inferior alveolar (mandibular) canal; 2) anterior loop and mandibular incisive canal; 3) mental foramen; 4) lingual canal; and 5) maxillary incisive/nasopalatine canal, and highlight the variability of imaging identification and characteristics of these structures in relation to implant placement 98‐109 . Hence, efforts are underway to automate identification of the mandibular canal 110 …”

Canal nutrício mimetizando reabsorção radicular externa

“…Esses canais são derivados do ramo incisivo do nervo alveolar inferior, sendo atribuídos a eles a função de promover um aporte nutrício entre os elementos neurovasculares e os dentes, como também, as suas estruturas adjacentes. Em radiografias periapicais essas composições são observadas como imagens radiolúcidas lineares entre os incisivos inferiores, que por vezes, podem ser de difícil identificação 4,5 . Um estudo recente demonstrou que a detecção dos canais nutrícios é extremamente favorecida pelo emprego de exames de TCFC 5 .…”
