“…IBH did not show any significant difference between the edentulous and dentulous sides in the present study which is in line with that reported among Italian patients ( 5 ). The lower values of SBH and BW in females compared to males are consistent with those reported previously for dentate ( 3 , 28 ) and edentate subjects ( 4 , 10 , 29 ). Promma et al .…”

“…The mandible forms the lower part of the face and is composed of the body and two rami ( 1 ). The posterior region of the mandible is highly vascularized due to the presence of the inferior alveolar bundles and the submandibular fossa, making it vulnerable during implant installation, third molar surgery, mandible osteotomy, or endodontic treatments ( 2 , 3 ). Successful dental implantation in posterior mandible mostly depends on two parameters for the long-term stability of the implant: protection of the inferior alveolar nerve (IAN) and sufficient alveolar bone volume ( 4 , 5 ).…”

“…Successful dental implantation in posterior mandible mostly depends on two parameters for the long-term stability of the implant: protection of the inferior alveolar nerve (IAN) and sufficient alveolar bone volume ( 4 , 5 ). Thus, accurate knowledge of the posterior region of the mandible is ineviTable to protect the IAN from any iatrogenic damage during invasive surgical procedures ( 3 , 6 , 7 ). Morphological variations in the mandibular canal (MC) are highly influenced by the differences in status, age, society, degree of mandibular atrophy, and the technique of assessment ( 1 , 8 , 9 ).…”

Background Precise preoperative knowledge of the mandibular canal (MC) variations and alveolar bone dimensions are vital elements for a successful dental implant. Thus, this study aimed to describe the three-dimensional morphology of the MC and alveolar bone dimensions, followed by a comparison of the variables in edentulous mandibular posterior sides with contralateral dentulous sides among adult Chinese individuals. Such variations were also studied in relation to gender and age. Material and Methods Cone-beam computed tomography (CBCT) was used for the morphometric analysis of the MC and alveolar bone dimensions in this cross-sectional study that analyzed retrospectively gathered data. Records of 112 individuals (56 males and 56 females) who had one edentulous mandibular posterior side and one dentulous side were included in the analysis. The MC position, length (MCL), and diameter (MCD) along with superior bone height (SBH) and bone width (BW) of the alveolar bone ridge were assessed. Results The MCD was lower at first ( p = 0.016) and second ( p = 0.079) molars on the edentulous sides. The SBH, BW1mm, and BW3mm were significantly lower on the edentulous than dentulous sides ( p < 0.05). However, there were no significant differences in the MC position or MCL and the incidence of bifid MC for dentulous and edentulous sides. Gender was a significant parameter for MCL, SBH, and BW, while no significant differences were observed in all variables on both sides in relation to age. Conclusions The position of the MC remains relatively constant regardless of losing teeth or increasing age. However, the MC position and MCL show differences in relation to gender. Alveolar bone dimensions are highly affected by dentate status followed by gender. Therefore, such variations should be considered by surgeons for successful surgical procedures in the posterior mandible. Key words: Mandibular canal, Bifid mandibular canal, edentulous mandible, alveolar bone dimension.

Mandibular canal vs. inferior alveolar canal: Evidence‐based terminology analysis

et al. 2020

View full text Add to dashboard Cite

Introduction The mandibular canal, as it was formerly named in Terminologia Anatomica (TA), has also been called the inferior alveolar (nerve) canal in many scientific publications. This study was conducted to investigate how these terms have been understood in different regions and different areas of expertise and to discuss the appropriate future application of the term “mandibular canal.” Methods A literature search was conducted using PubMed, and articles using different terms for this structure were classified into two groups, inferior alveolar canal/inferior alveolar nerve canal (IAC/IANC) and the mandibular canal (MC). The 50 most recent articles in each group were included. Publication year, journal title, country of the first author, and affiliation of all authors were recorded in both groups for all 100 articles. Results There was a significant difference between the IAC/IANC and MC groups in the numbers of anatomy journals, other journals, and anatomy affiliations. Turkey published most frequently with a total of 15 articles, followed by Iran with 10 articles, and China/India/United States with seven each. When the six countries of the first author that had three or more publications in each group were compared, only Turkey appeared in both groups; otherwise, different countries were in the two groups. Conclusions Based on the results of this analysis, and considering that the tentative new term “inferior alveolar foramen” is used in the latest TA, we suggest that the mandibular canal should be renamed the “inferior alveolar canal.”
