Introduction & Objective: In the mandibular posterior region, there are several vital anatomical structures,
including the lower canal and lower alveolar nerve, chin hole and submandibular gland fossa. The sub
mandibular gland fossa is in fact a dentin at the lingual plate of mandible trunks below the line of myloicheidoid
and there is submandibular salivary gland. Damage to the arteries of the mouth, and paresthesia in the affection
to the lower canal and lower alveolar nerves, can be as a result of perforation into the cavity. The prevention
of these problems during implanting is the primary goal of the surgeon, which is carried out through a clinical
examination and accurate radiography examination of the patient. The aim of this study was to investigate the
submucosal cavity displacement by CBCT in patients referred to oral and oral radiology center in Yasuj 20172018.
Methods: In this cross-sectional study, 70 samples of low oral images were selected from the archives of the
Radiology Center.The deepest part of the submandibular cavity was then determined in the insert. It was then
measured in the cross-sectional view by the OnDemand3D digital ruler. Also, the distance between the
mandibular canal and the cavity was measured by a digital ruler. Data was analyzed by SPSS software version
23 using descriptive statistics (mean, standard deviation, frequency distribution) and analytical (T-test) and
correlation) were analyzed.
Results: The results of this study showed that the mean submandibular cavity depth of the right side was 2.08
± 0.73 mm and the left side was 2 ± 0.65 mm. Depth of right subendibular cavity of most specimens (72.8%) is
below 2.5 mm. On the left side, the majority of samples (82.9%) were less than 2.5 mm. The mean gap
between the right mandibular canal and the left mandibular canal was 1.94 ± 1.8 mm and 1.73 ± 0.7 mm,
respectively. The mean cavity distance to the right crest ridge was 13.8 ± 3.2 mm and the mean cavity to left
crest ridge was 14 ± 3.7 mm.
Conclusion: The results of this study showed that considering the anatomical diversity of the submandibular
cavity in depth, the distance between the cavity and the mandibular canal, and the distance from the cavity to
the crust of the alveolar ridge, a precise radiographic examination of the area to prevent Complications and
complications during implant surgery are very important.According to the results obtained from CBCT imaging
studies, considering the quality of imaging, its accuracy and resolution in detecting and determining, the
position of the depth of the submandibular cavity, the cavity gap to the ridge crests, and the cavity-to-canal
spacing Mandibular has a very high performance.
