WHEN TO USE NON-HEX (NON-ENGAGING) DENTIUM ABUTMENTS
Core Principle: Flexibility for angled implants or multi-unit prosthetics.
- Angled Implants (≥15°)
o Scenario: Tilted placements (e.g., posterior maxilla avoiding
sinus/nerves).
o Why: Bypasses hex-alignment conflicts; simplifies seating. - Multi-Unit Bridges/Full-Arch Restorations
o Scenario: Implants splinted via fixed prosthesis.
o Why: Prosthesis provides anti-rotation; hex redundancy reduces
complexity. - Cement-Retained Crowns
o Scenario: Final crown cemented to abutment.
o Why: Cement seals margins; hex offers no added benefit. - Thin Tissue Biotypes
o Scenario: Delicate gingiva (e.g., anterior aesthetics).
o Why: Low-profile non-hex designs minimize pressure on tissue.
⚖ KEY DECISION-MAKING FACTORS
Factor | Hex Preference | Non-Hex Preference |
---|---|---|
Implant Angle | Straight (0–10°) | Tilted (≥15°) |
Restoration Type | Single crown | Bridge/full arch |
Retention | Screw-retained | Cement-retained |
Tissue Thickness | Standard (≥3mm) | Thin (<2mm) |
Bone Density | Dense (Type I–II) | Soft (Type III–IV) |
⚠ PROFESSIONAL NOTES
- Torque Limits:
o Hex: Up to 35N·cm (check implant system specs).
o Non-Hex: Max 10N·cm (per Dentium guidelines). - Tissue Contouring: Non-hex often preferred for optimal emergence profile.
- Compatibility: Verify platform matching (e.g., Ø4.0/4.5/5.5mm).
SUMMARY
“Hex for stability, Non-Hex for flexibility.”
- Hex: Ideal for single straight implants needing anti-rotation.
- Non-Hex: First choice for angled implants, bridges, or cement-retained cases.
