Placing implants in the posterior mandibular region could present some difficulties and risks. Specifically, a lingual undercut is often found that may become hard to manage if a lingual or buccal perforation occurs. A recent study 1 evaluated one hundred and fifty-one computed tomography (CT) examinations of patients who were retrospectively evaluated to determine anatomical variations in bone morphology in the submandibular fossa region.
Mandibles with any lingual concavity present a potential increased risk of lingual cortical perforation during implant placement surgery. CT imaging allows characterizing the anatomy of the submandibular fossa and provides other important information for the preoperative assessment of the posterior mandible for dental implants placement.
What has been your experience placing implants in the posterior mandibular region? How have you dealt with the potential risks?
