Thinking about chairside milling as part of your same-day dentistry program? Join the practices set up to offer same-day restorations, reduce outsourcing costs, and improve patient satisfaction.
Among the leading contenders in this space are the Perfit Ovis, Dentsply Sirona PrimeMill, and Glidewell FastMill.io.
Let’s break down how these three systems compare across major categories.
1. General Overview
| Feature | Perfit Ovis | Dentsply Sirona PrimeMill | Glidewell FastMill.io |
|---|---|---|---|
| Axis | 4-axis | 4-axis | 4-axis |
| Workflow Type | Open | Semi-Closed | Closed |
| Materials | Fully sintered zirconia, lithium silicates, porcelains | Zirconia, lithium silicates, PMMA | Glidewell proprietary blocks |
2. Material Capabilities & Versatility
Perfit Ovis supports a wide range of materials—especially valuable for labs and dentists wanting to work with both fully sintered zirconia and lithium silicates.

Winner for Material Versatility: Perfit Ovis
PrimeMill expands on this with zirconia, lithium silicates, and PMMA—great for more complex cases but tied to the CEREC workflow unless unlocked at a cost.
FastMill.io is limited to Glidewell's own blocks (BruxZir, Obsidian, etc.), which simplifies workflow but limits flexibility.
3. Speed & Productivity
| Task | Perfit Ovis | PrimeMill | FastMill.io |
|---|---|---|---|
| Zirconia Mill Time | 13 minutes | 10 minutes | 40 minutes |
| Lithium Silicates Mill Time | 8–10 minutes | 5–10 minutes | 15–20 minutes |
PrimeMill is marginally faster, especially on lithium silicates, but Perfit Ovis performs exceptionally well with fully sintered zirconia, reducing post-processing time.

Winner for Zirconia Speed: PrimeMill

Winner for Balance of Speed & Openness: Perfit Ovis
4. Spindle, Tools, and Hardware Considerations
| Feature | Perfit Ovis | PrimeMill | FastMill.io |
|---|---|---|---|
| Dual Spindle | ✅ Yes | ✅ Yes | ❌ No |
| Spindle Type | Compressor-driven | Compressor-driven | Electric |
| Tool Changer | ✅ Yes, 5 tools | ❌ Holds 4 tools | ❌ Single tool |
| Bur Replacement | Manual by hand | Specialized wrench | Specialized wrench |
| Motor Type | Servo | Step w/ feedback | Step |
Perfit Ovis stands out for its automatic tool changer, servo motors, and dual spindle—all packed into a cost-effective, open system.
5. Software & Scanner Compatibility
| Feature | Perfit Ovis | PrimeMill | FastMill.io |
|---|---|---|---|
| IOS Scanner Compatibility | Any | Sirona IOS, 3Shape (limited) | iTero, Medit |
| CAD Software | Open (Exocad, etc.) | CEREC Software (closed) | FastMill.io Software (closed) |
Perfit Ovis gives users the most flexibility to integrate with any scanner and any CAD software, offering the greatest freedom for labs and practices wanting to stay nimble.
6. Cost Comparison
| Mill | Price Range |
|---|---|
| Perfit Ovis | $$ (Mid-tier) |
| PrimeMill | $$$$ (High-end) |
| FastMill.io | $$ (Mid-tier, but closed ecosystem) |
Perfit Ovis strikes an ideal balance between cost and capabilities. PrimeMill offers power and speed, but at a significantly higher price point. FastMill.io is affordable but limits users to Glidewell’s closed system.
Final Verdict
| Use Case | Best Option |
|---|---|
| Open Workflow Flexibility | Perfit Ovis |
| Fastest Milling Speeds | PrimeMill |
| Lowest Operational Complexity | FastMill.io |
| Best ROI per Restoration | Perfit Ovis |
