WHEN TO USE NON-HEX (NON-ENGAGING) DENTIUM ABUTMENTS

Core Principle: Flexibility for angled implants or multi-unit prosthetics.

  1. Angled Implants (≥15°)
    o Scenario: Tilted placements (e.g., posterior maxilla avoiding
    sinus/nerves).
    o Why: Bypasses hex-alignment conflicts; simplifies seating.
  2. Multi-Unit Bridges/Full-Arch Restorations
    o Scenario: Implants splinted via fixed prosthesis.
    o Why: Prosthesis provides anti-rotation; hex redundancy reduces
    complexity.
  3. Cement-Retained Crowns
    o Scenario: Final crown cemented to abutment.
    o Why: Cement seals margins; hex offers no added benefit.
  4. 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

FactorHex PreferenceNon-Hex Preference
Implant AngleStraight (0–10°)Tilted (≥15°)
Restoration TypeSingle crownBridge/full arch
RetentionScrew-retainedCement-retained
Tissue ThicknessStandard (≥3mm)Thin (<2mm)
Bone DensityDense (Type I–II)Soft (Type III–IV)

⚠ PROFESSIONAL NOTES

  1. Torque Limits:
    o Hex: Up to 35N·cm (check implant system specs).
    o Non-Hex: Max 10N·cm (per Dentium guidelines).
  2. Tissue Contouring: Non-hex often preferred for optimal emergence profile.
  3. 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.
