Implant Insertion & Abutment Torque Reference Guide

Section 01

Insertion Torque Guidelines

Recommended insertion torque values by implant system and bone quality (Lekholm & Zarb classification D1–D4). Minimum torque for immediate loading and maximum safe torque to avoid microfracture.

Implant System	Bone Quality	Min for Immediate Loading	Max Safe Torque	Clinical Notes
Neodent Helix GM	D1–D2	35 Ncm	70 Ncm	Dual taper, aggressive thread pitch
Neodent Helix GM	D3–D4	25 Ncm	50 Ncm	Use Acqua surface for D3–D4; underprepare
Neodent Drive GM	D1–D2	40 Ncm	80 Ncm	Designed for high initial stability
Neodent Drive GM	D3–D4	30 Ncm	60 Ncm	High torque retention even in poor bone density
Neodent Titamax GM	D1–D2	32 Ncm	60 Ncm	Cylindrical body; relies on cortical anchorage
Neodent Helix Short	D1–D2	35 Ncm	70 Ncm	Underprepare 1 drill size; bicortical anchorage ideal
Straumann BLT	D1–D2	35 Ncm	70 Ncm	SLA or SLActive surface; Loxim driver required
Straumann BLX	D1–D2	40 Ncm	80 Ncm	Self-tapping; excellent primary stability in all bone types
Straumann TLX	D1–D2	35 Ncm	70 Ncm	Tissue-level; shoulder at mucosal margin
SIN Epikut CM	D1–D2	30 Ncm	60 Ncm	Cone Morse connection; self-locking taper

Legend: Neodent GM Straumann SIN Min = Minimum for immediate loading Max = Maximum safe insertion torque

Section 02

Abutment & Prosthetic Component Torque

Final torque values for abutment screws, MUA screws, Ti-Base screws and prosthetic components. Always use a calibrated torque wrench and follow a re-torque protocol.

Component	System	Torque	Notes
MUA Screw	Neodent GM	32 Ncm	Grand Morse Connection; self-locking taper aids seating
MUA Screw	Straumann BLT/BLX	35 Ncm	CrossFit connection; use Loxim or direct driver
Ti-Base Screw	Neodent GM	20 Ncm	Prosthetic phase; cement or screw-retained crown
Ti-Base Screw	Straumann	35 Ncm	Prosthetic phase; verify screw access channel alignment
Cover Screw	Neodent GM	10 Ncm	Finger tight + 1/4 turn; do not overtighten
Healing Abutment	Neodent GM	15 Ncm	Check tissue contour at 2 weeks
Healing Abutment	Straumann	15 Ncm	SynOcta or RC; tissue shaping phase
Final Abutment	Neodent GM	32 Ncm	Grand Morse; apply cotton pellet over screw head
Final Prosthetic Screw	All Systems	15–20 Ncm	Per individual manufacturer specification; verify against IFU

Clinical Tips

Best practices to optimize insertion torque outcomes and protect bone and implant integrity.

🔧

Use a Calibrated Torque Wrench

Always use a factory-calibrated torque wrench. Uncalibrated devices can under- or over-torque by 20–30%, compromising primary stability and risking bone damage.

📐

Tilted Implants — Adjust Accordingly

Torque values are reference values for axially placed implants. Tilted or angulated implants (>15°) may require adjustment. Consult system IFU for angled placement protocols.

🦴

D4 Bone — Underprepare

In D4 (very low density) bone, stop one drill size short of the final diameter or use an osteotome technique. This compresses the bone rather than cutting it, increasing bone-to-implant contact.

⏱

Re-Torque Protocol

Check and re-torque abutment screws at the 10-minute mark after initial placement. Stress relaxation in the screw-implant interface is common and re-torquing restores optimal clamping force.

Clinical Disclaimer: These values are guidelines based on manufacturer recommendations and published literature. They are provided for reference purposes only. Always follow your implant system's specific Instructions for Use (IFU). Clinical judgment, patient anatomy and bone quality must guide the final protocol.
