Nerve Path Safety: Protecting Your Oral Health

When placing implants in the lower back jaw, the most critical structure is the Inferior Alveolar Nerve (IAN). This nerve provides sensation to your lower lip and chin. Safeguarding it is our #1 surgical priority.

Mapping the Nerve

Using 3D CBCT data, we digitally trace the exact path of the IAN. This allows us to maintain a mandatory 2mm safety zone between the implant and the nerve canal.

Surgical Protocols:

• Guided Surgery: 3D-printed guides lock the drill path, making it physically impossible for the drill to go deeper than the pre-planned safety depth.
• Short Implants: In cases of low bone height, we use specialized wide, short implants to avoid the nerve entirely.
• Nerve Repositioning: In extreme cases, a specialist can move the nerve slightly—though this is rare and advanced.
