Tunnelling Instruments in Periodontal Surgery: A Practical Overview

Tunnelling instruments are designed for minimally invasive periodontal techniques, where the goal is to create a surgical pathway with the least possible disruption to surrounding tissue.

What Tunnelling Instruments Do

These fine, often curved instruments help the clinician create a subperiosteal tunnel for grafting material or to reposition tissue, without the need for a large open flap.

Design Considerations

A good tunnelling instrument has a slim profile, a smooth rounded tip to avoid perforating tissue, and enough rigidity to maintain control while working blind in a confined space.

Who Uses Them

Periodontists performing root coverage procedures and minimally invasive grafting rely heavily on this instrument category, often alongside microsurgical technique and magnification.
