Periosteal Elevators in Oral Surgery: Molt, Freer, Prichard & Buser

Periosteal elevators are among the most-used instruments in oral and implant surgery. Their job is simple but critical: to lift and reflect the mucoperiosteum — the soft-tissue and periosteal layer — cleanly away from the underlying bone so the surgeon can see and work at the surgical site. This guide explains the main patterns, how they differ, and how to choose between them.

What a periosteal elevator does

After an incision, the periosteal elevator separates the flap from bone in one continuous, controlled layer. Working in the correct sub-periosteal plane keeps the flap intact, reduces tearing and bleeding, and supports faster healing. Most elevators have a rounded or pointed working end and a flat, slightly concave blade that follows the bone surface.

Common patterns

• Molt: A popular double-ended elevator, with a pointed end to start the reflection at the papilla and a broader rounded end to continue it. Available in several blade widths.
• Freer: A slim, double-ended elevator with a sharp and a blunt end, ideal for delicate flap work and narrow sites.
• Prichard: A broader elevator often used in periodontal and implant surgery for reflecting and holding larger flaps; available in different blade lengths.
• Buser: A pattern favoured in implant and regenerative surgery for atraumatic flap elevation.
• Allen: Offered in anterior and posterior designs to match different regions of the arch.

Single- vs double-ended

Double-ended elevators combine two working ends in one instrument, reducing the number of instruments on the tray. Single-ended designs can offer a more balanced grip for repetitive work. The choice is largely down to personal preference and the procedure.

Choosing the right elevator

Match the blade width to the site: narrow blades for interproximal and anterior areas, wider blades for posterior and full-thickness flaps. A sharp, well-finished edge is essential — a dull elevator tends to tear rather than lift tissue. Surgical stainless steel that holds its edge and withstands repeated autoclaving is the standard choice.

Care and maintenance

Clean and inspect the working edge after every use, and keep elevators separated during sterilisation to protect the tips. A nicked or bent blade should be re-finished or replaced, since edge quality directly affects how atraumatic the reflection is.
