Periosteal Elevators Explained: Types, Uses, and Care

Periosteal elevators are a staple of oral surgery, used to reflect the mucoperiosteal flap and expose underlying bone. Selecting the correct design speeds up surgery and reduces tissue trauma.

Common Designs

The Molt elevator features a curved, sharp end for fine periosteal work and a rounded end for broader elevation. The Woodson and Freer patterns offer thinner blades suited to delicate interdental work.

Choosing the Right Size

Smaller elevators are better for anterior, tightly spaced sites, while wider blades speed up flap reflection in posterior areas with more room to work.

Instrument Care

Because the working edge needs to stay sharp to avoid tearing tissue, periosteal elevators should be inspected regularly and sharpened or replaced when the edge becomes dull. Proper ultrasonic cleaning and autoclaving between uses preserves the finish and extends instrument life.
