Description
Diamond ACI ACII FGM – Composite Finishing & Pre-Polishing Paste
Diamond ACI ACII FGM is a two-step diamond-based polishing paste system designed for finishing and pre-polishing composite restorations and other dental materials. The system combines high-hardness diamond abrasives with Carbowax lubricant to ensure controlled abrasion and smooth surface refinement.
It includes:
Diamond ACI – 80 microns (Medium Grit)
Diamond ACII – 30 microns (Fine Grit)
Diamond Polishing Paste Specifications
Abrasive Type: Diamond particles
Lubricant Base: Carbowax
ACI Particle Size: 80 µm (Medium)
ACII Particle Size: 30 µm (Fine)
Water Soluble: Yes
Consistency: Thixotropic
Two Grit System for Controlled Finishing
The combination of two grit levels allows progressive surface refinement:
ACI (80 µm): Used for finishing and contouring after composite placement.
ACII (30 µm): Used for pre-polishing to refine surface texture before final gloss.
This sequential system enhances surface smoothness and prepares restorations for high-luster polishing.
Thixotropic Formula for Easy Handling
The paste remains stable during application and does not run off the surface. Its thixotropic behavior improves control during polishing procedures.
Water-Soluble & Easy Cleanup
The formulation rinses off easily with water, allowing efficient cleaning after polishing without residue.
Clinical Indications
Finishing composite restorations
Pre-polishing anterior restorations
Surface refinement before final polishing
Adjustment of direct restorations
Refinement of indirect restorations
Step-by-Step Clinical Protocol
Prepare the restoration surface and ensure proper contouring.
Apply Diamond ACI (80 µm) using a felt disk to refine and smooth the surface.
Apply a small amount of Diamond ACII (30 µm) on a felt disk or directly on the tooth for pre-polishing.
Repeat polishing as needed until desired smoothness is achieved.
For final high-gloss finish, use Diamond Excel (FGM) or Diamond R (FGM).
Proper initial surface preparation significantly influences final brightness.
