Atraumatic extraction — luxators, periotomes & elevators explained
Modern extraction protocol favours bone preservation over brute force. Here's how luxators, periotomes and elevators differ — and how to build a kit that protects the ridge for future implant placement.
The shift from forceps-first extractions to atraumatic, bone-preserving technique has reshaped the surgical kit. Today's protocol uses luxators or periotomes to sever the periodontal ligament before any rotational force is applied — protecting the buccal plate and preserving ridge volume for future implant placement. ErgoDenta carries 20 ErgoLite Luxating Elevators plus 100+ classic elevators across the Apexo, Bein, Cryer and Heidbrink families.
Why atraumatic extraction matters
The classic forceps-first extraction trades short procedural time for bone trauma — the buccal plate often fractures when forces are applied before the periodontal ligament has been cut. For implant-driven practices that's a real cost: every millimetre of buccal bone lost extends the timeline and increases the chance of needing a graft.
Atraumatic protocol reverses the order. The periodontal ligament is severed circumferentially with a fine luxator or periotome before any rotational force. Once the ligament is cut, elevators or forceps can deliver the tooth with minimal pressure and minimal bone trauma.
Chapter 2The three instrument families
- Periotomes — the finest blade. Ultra-thin (0.4–0.7 mm) with a sharp cutting edge designed to slip into the periodontal ligament space and sever the fibres without elevating bone. Used first in any atraumatic protocol.
- Luxating elevators — wider blade (1–5 mm) designed to combine cutting with gentle elevation. Inserted into the PDL and rotated slightly to expand the socket and break remaining fibres. The ErgoLite range covers straight, curved and dual-edge geometries.
- Classic elevators — Apexo (straight blade), Bein (root tip), Cryer (right/left angled), Heidbrink (root tip scaler). Used for elevation and root tip removal once luxation is complete.
Step-by-step protocol
The standard atraumatic sequence:
- Anaesthesia + soft-tissue release — minimal flap, just enough to expose the cervical margin.
- Periotome circumferentially — slip the periotome into the PDL space at the mesial, distal, buccal and lingual surfaces. Light apical pressure, no levering.
- Luxator follow-through — once the PDL is cut at the cervical level, switch to a luxator (start with 1–2 mm, escalate to 3–5 mm as needed) to extend the cut apically and gently expand the socket.
- Elevator if needed — for stubborn roots, an Apexo or Bein elevator gives the leverage to deliver the root with controlled rotation.
- Forceps last (if at all) — by this point most teeth deliver with very light forceps engagement, often without any significant force.
- Socket assessment — inspect the buccal plate. With proper atraumatic technique, the plate should remain intact.
ErgoDenta's atraumatic kit
The ErgoLite Luxating Elevator range is colour-coded by working-end size — yellow (1 mm), pink (2 mm), orange/black (3 mm), red (5 mm), green dual-edge (3-1.5 mm), dark grey dual-edge (5-3 mm) — making sequence selection visual.
Two sub-ranges:
- Standard ErgoLite — colour-anodised steel working end on the ErgoLite hollow handle.
- ErgoLite Gold — TiN gold-coated working end for additional surface hardness and a clear visual signal that the instrument is in the atraumatic range.
Layered with the classic Apexo (straight, 2.5/2.7/3 mm), Bein (Fig. 1/2/3) and Heidbrink (root tip scaler, left/right/straight, 1.5/2.5 mm) ranges, the full surgical kit covers everything from initial luxation to apical root tip removal.
Chapter 5Common mistakes to avoid
- Skipping the periotome step — the most common cause of buccal plate fracture. Even a single circumferential pass changes everything.
- Levering against the buccal plate — the lingual / palatal cortex is much stronger; use it as the fulcrum point, not the buccal.
- Wrong-size luxator — starting with a 5 mm luxator on a thin lower incisor will fracture the root. Always start with the smallest size that fits the PDL.
- Forcing rotation too early — if the tooth doesn't rotate easily, the PDL isn't fully cut yet. Go back to the luxator before applying more force.
- Dull luxator edges — a dull luxator becomes a wedge instead of a cutter. Sharpen routinely or use ErgoRazor® variants.

What is the difference between a luxator and an elevator?
A luxator is designed primarily to cut the periodontal ligament with a fine sharp blade — used at the start of an atraumatic extraction. A classic elevator is designed to lever the root once the PDL has already been cut. The luxator is a cutting tool first, the elevator is a mechanical advantage tool first.
When should I use a periotome instead of a luxator?
Use a periotome when the case calls for absolute minimum bone trauma — typically extractions in the aesthetic zone or sites planned for immediate implant placement. The periotome is finer (0.4–0.7 mm) than even the smallest luxator, so it slips into the PDL space without expanding the socket. The luxator follows once the periotome has cut the cervical PDL.
Which luxator size should I start with?
Always start with the smallest size that fits the PDL space — usually 1 mm or 2 mm. Escalate to 3 mm and 5 mm only as the socket expands. Starting too large fractures the root or buccal plate. The ErgoLite colour-coded sequence (yellow → pink → orange → red) reflects this size escalation.
Can I do atraumatic extraction without a periotome?
Yes — many practitioners use a fine 1 mm luxator as their first instrument and skip the dedicated periotome step. The principle is the same: cut the PDL before applying any rotational force. A dedicated periotome is finer and gives more control in aesthetic-zone cases, but a sharp 1 mm luxator achieves a similar result in most situations.
Does atraumatic extraction take longer than conventional?
It takes 2–5 minutes longer per extraction in average cases, but it dramatically reduces post-operative complications, preserves ridge volume for future implant placement, and reduces the need for socket grafting. For implant-driven practices, the time investment pays back in shortened overall treatment timelines.
What's the colour-coding on ErgoLite Luxating Elevators for?
Each working-end size has a unique colour at the ferrule: yellow (1 mm), pink (2 mm), black/orange (3 mm), red (5 mm), green (3-1.5 mm dual edge), dark grey (5-3 mm dual edge). The colour lets the surgeon and assistant identify the right instrument at a glance during the sequence.
How do I choose between standard ErgoLite and ErgoLite Gold luxators?
ErgoLite Gold has a TiN (titanium nitride) gold-coated working end that adds surface hardness and gives a clear visual signal that the instrument is the atraumatic version. Standard ErgoLite uses anodised colour-coded ferrules with a polished steel working end. Performance is comparable; the Gold variant is purely a hardness + visual upgrade.
Are Apexo elevators still relevant if I have luxators?
Yes — Apexo elevators (straight blade, 2.5/2.7/3 mm) are still the workhorse for elevating roots once the PDL has been cut. Luxators do the cutting; Apexo gives the controlled mechanical advantage to deliver the root. Most surgical kits include both because they serve different stages of the protocol.
What's a Heidbrink root tip scaler used for?
Heidbrink root tip scalers are designed for retrieval of small root fragments left in the socket after extraction. The thin angled blade slips into the socket and engages a fragment for elevation. Available straight, left and right curved in 1.5 mm and 2.5 mm sizes — keep at least one set in the surgical kit for unexpected fractures.
How do I keep luxators sharp?
Sharpen the cutting edge with a flat sharpening stone at a 15–20° angle to the blade — much shallower than a curette angle. Sharpen lightly and frequently rather than aggressively and rarely. ErgoRazor® variants use cryogenically treated 440C steel that holds the edge up to 3× longer; they're worth the upgrade for high-volume surgical practices.
