Dental Root Elevators Complete Guide — Apical, Bein, Seldin, Cryer and Luxator

Dental root elevators are the instruments that do the actual work of luxating a tooth before a forceps extraction — and they are also the instruments responsible for most of the post-extraction complications when chosen or used incorrectly. Understanding the design differences between apical, straight, curved, and specialized elevators helps both clinicians and procurement teams assemble instrument sets that work for the actual extraction mix in their practice.

How Root Elevators Work

Root elevators work on three mechanical principles depending on the instrument type:

• Lever principle — the elevator blade is inserted between the tooth root and the alveolar bone; the elevator handle acts as a lever with the alveolar bone crest as the fulcrum; rotating the blade expands the periodontal ligament space and moves the tooth coronally
• Wedge principle — the tapered blade is driven apically into the periodontal ligament space, wedging the tooth coronally as the blade advances
• Wheel and axle principle — rotating the instrument around its long axis when the blade is engaged in the PDL space generates lateral movement; this is how cryer elevators (triangular blade) function

Straight Elevators (Coupland/Warwick James)

Straight elevators are the first elevators taught in dental schools and the most commonly purchased. They come in three sizes:

• No. 1 (narrow, 3 mm blade) — for incisor and fine root work; lower premolar space; initial periodontal ligament entry
• No. 2 (medium, 4 mm blade) — the general-purpose size; works for most single-rooted premolars and canines
• No. 3 (broad, 5 mm blade) — for larger single roots and initial molar root separation in surgical extractions

Cryer Elevators (Triangular Blade — Right and Left)

Cryer elevators have a triangular concave blade and come as a matched right-left pair. They are used for inter-radicular bone after root separation in lower molar extractions. After the crown is removed or the roots are separated, the Cryer blade is placed in the inter-radicular septum socket and rotated — the triangular blade engages the remaining root and pries it from its socket using the wheel-and-axle principle. Every lower molar extraction set should include both right and left Cryer elevators.

Apical Elevators

Apical elevators are fine-tipped, thin-bladed instruments designed for accessing the apical third of the root socket — primarily for removing retained root tips after fracture during extraction. The blade is narrow (1.5 to 2 mm) and angled to reach the apex of a socket that a straight elevator cannot access without damaging adjacent alveolar bone.

• Straight apical elevator — for anterior teeth with straight roots
• Left-curved apical elevator — for reaching the apex of the upper left posterior roots
• Right-curved apical elevator — for the upper right posterior root apices

Bein Elevator

The Bein elevator has a narrow straight blade with a slight curve at the tip. It is used for luxating upper incisors and canines before forceps application, and for initial entry into the PDL space in tight alveolar bone where the Warwick James No. 1 is too wide. The Bein is also used for small root tip removal in cases where the apical elevator is too angled for the approach angle required.

Seldin Elevator

The Seldin elevator is a double-ended instrument with a small and a medium straight blade on opposite ends. It functions similarly to the straight Warwick James elevator but offers two working widths in one instrument, reducing tray instrument count. Common in oral surgery and periodontal surgery sets where instrument number per tray is managed carefully.

Luxator (Periotome-Style Elevator)

Luxators have ultra-thin, sharp-edged blades designed to sever the periodontal ligament fibers by cutting rather than displacing them. Unlike conventional elevators that work by pressure and rotation, a luxator is pressed apically along the root surface with controlled vertical force, cutting the PDL fibers progressively. This produces significantly less force on the alveolar bone and is particularly valuable for preserving the extraction socket for immediate implant placement. See our separate guide on the Periotome for detailed information on this instrument type.

Steel Quality and Blade Maintenance

Elevator blades must maintain a working edge through hundreds of sterilization cycles and the physical stress of root luxation. Fizza Surgical root elevators are manufactured from 316L stainless steel with blade tips heat-treated for hardness. All instruments are manufactured under ISO 13485:2016 with CE marking.
