CLEARFIL AP-X

• Accurate shade matching for aesthetic restorations.

• High polishability and smooth surface finish (important for both aesthetic and hygienic aspects).

• High wear resistance and fracture resistance, suited for posterior load-bearing areas.

• Low polymerization shrinkage (thanks to high filler loading) reducing stress and marginal leakage risk.

• Good radiopacity (filled with barium glass particles) for X-ray visibility.

• Easy handling: optimal viscosity, non-stickiness to instruments, good for sculpting in various cavity types.

⚙️ Technical Specifications

Here are some of the key specs from the manufacturer’s brochure:

• Filler loading: ~ 86 wt% (~70 vol %) in some versions.

• Compressive strength: ~ 449 MPa for CLEARFIL AP-X (in one test).

• Flexural strength: ~ 204 MPa in that same test.

• Toothbrush abrasion: around 0.33 mm³ in one test (indicating good wear resistance).

• Shrinkage: one listing reports polymerisation shrinkage of ~1.9%.

• Indications:

  • Class I, II, V restorations of posterior teeth.

  • Class III, IV, V restorations of anterior teeth.

  • Cervical cavities or defects involving root surfaces (wedge-shaped defects) in some cases.

• Shade range: available in many VITA® shades: A2, A3, A3.5, A4, B2, B3, B4, C2–C4, XL (transparent) etc.

📝 Clinical Notes / Usage Tips

• Because of its high filler content and low shrinkage, it is well suited for posterior restorations where wear and strength are key.

• The aesthetic polishability and shade matching make it also appropriate for anterior restorations, especially when you want a durable composite that also looks good.

• Handling is optimized (non-sticky, good sculptability) so you should find it comfortable for both build-up and contouring.

• Even though it is universal, always ensure proper isolation, bonding protocol, incremental placement especially in deeper cavities to ensure optimal polymerization and behaviour.

• Choose the appropriate shade and translucency depending on location (anterior vs posterior) and cavity depth; the XL transparent shade can be useful for layering or as a base.
