What does “Implant-related nerve injury” mean?
Implant-related nerve injury is a complication in which implant placement or changes in surrounding tissues affect nerve function, causing reduced sensation, tingling, pain, or other symptoms.
Sensory changes vary by location
In the lower jaw, nerves related to sensation in the lower lip, chin, and teeth, and nerves supplying tongue sensation, may lie near the surgical site. Reduced sensation, tingling, or unusual feelings may persist, requiring identification of their location and extent.
Preoperative imaging and position planning
Placement length, depth, and direction are planned according to remaining bone height and the nerve canal’s position. Necessary imaging and clinical examination are combined; imaging-based planning does not eliminate surgical error. Other anatomical risks are assessed according to the site.
Checking sensation after anesthesia
If altered sensation persists or worsens beyond the expected end of anesthesia explained to you, promptly notify the operating clinic. Recording onset, extent, and changes helps assessment. The course depends on injury severity and cause, so do not assume a recovery period.
Frequently Asked Questions
Does numbness immediately after surgery mean nerve injury?
Local anesthesia may still be active. If reduced sensation persists beyond the advised duration or new changes develop, a dentist should assess it.
Does tingling always recover on its own?
Some temporary changes recover, while others persist. The cause and severity require assessment to determine necessary care and follow-up.
