What is the minimum required distance for implant placement from the Inferior Alveolar Nerve (IAN)?

The minimum required distance from the Inferior Alveolar Nerve (IAN) for implant placement is recognized as 2 mm. This distance is crucial for several reasons. First, maintaining a minimum distance helps prevent nerve injury during the placement procedure, which can lead to complications such as sensory disturbances or paresthesia in the areas innervated by the IAN.

Moreover, positioning the implant at least 2 mm from the nerve ensures adequate bone support and stability for the implant while allowing for proper healing and osseointegration. Insufficient distance could compromise the integration of the implant due to potential bone resorption and increased risk of failure.

In clinical practice, adhering to this guideline can significantly enhance the success rate of implant procedures and minimize complications related to nerve damage. Keeping a safe distance helps in achieving long-term functional and aesthetic outcomes for patients requiring dental implants in the mandible.
