IMPORTANCE OF BIFID MANDIBULAR CANAL IN IMPLANTOLOGY AND IN ORAL SURGERY: REVIEW OF THE LITERATURE AND REPORT OF THREE CASES
Abstract
The mandibular canal or the
inferior alveolar canal typically extends from the mandibular foramen to the mental foramen and includes the
inferior alveolar artery, vein and the inferior alveolar nerve. During
embryonic development three canals fuse to form a single canal. Failure of
these canals to fuse can explain presence of multiple canals in some
individuals. It is important to localize the course of the mandibular canal at
the site of implant placement as altered sensation of the inferior lip due to
inferior alveolar nerve injury. It is one of the most serious complication of
mandibular implant surgery. Also the
difficulty in performing mandibular anesthesia is the other problematic issue
for patients and the clinicians.
The purpose of this study is to call
attention to a rare anatomical variation. This case report reveals an unusual
variant of the bifid mandibular canals. Three new cases, two of which are in
the same family, have been presented.
