Three-step polishing system

Three-step polishing system kit is a material-specified professional finishing assembly designed for global dental prosthetic laboratories, fitted with standard 2.35mm HP stainless steel shanks fully compatible with mainstream low-speed straight micromotor handpieces. This three-gradient grit workflow realizes progressive surplus removal, contour smoothing and mirror high-gloss finish in sequence, eliminating messy polishing paste and water cooling procedures to streamline lab operation drastically.

TH0306 is customized exclusively for all-zirconia restorations, engineered for occlusal adjustment and full-surface polishing of zirconia veneers, inlays, crowns and bridges. Its matched graded abrasives deliver stable dry grinding performance without auxiliary polishing media or liquid cooling, avoiding water residue contamination on high-purity zirconia crystalline structures. TH0406 caters to full ceramic systems, covering lithium disilicate glass ceramic, cast porcelain and metal-bonded porcelain prostheses, suitable for both blank pre-finishing and post-glaze occlusal trimming with zero paste and water required.

Each kit contains 6 shaped polishing heads including flat disc, wide wheel and pointed bullet geometries, covering broad occlusal planes, tight marginal gaps and curved veneer contours uniformly. Every bur passes strict concentricity inspection before packaging to ensure low-vibration stable rotation during long batch production runs. The flexible elastic abrasive matrix evenly disperses grinding pressure, effectively preventing brittle ceramic edge chipping, surface scratches and hidden micro-cracks that lead to costly workpiece scrap loss.

Housed in a solid plastic holder tray, the kit keeps all 6 burs neatly organized for convenient storage, transport and quick access during daily technician workflows. Consistent abrasive particle bonding delivers long-lasting uniform polishing results, making this three-step set a high-efficiency staple consumable for small custom dental workshops and large-scale centralized prosthetic manufacturing facilities worldwide.

• Standard 2.35mm HP stainless steel shank, universal fit for all dental lab low-speed straight handpieces
• Two dedicated models: TH0306 (zirconia exclusive) & TH0406 (full ceramic & metal porcelain exclusive)
• 6 polishing burs per kit with multi-shape designs for full occlusal, marginal and curved surface coverage
• Complete three-stage coarse-medium-fine sequential polishing workflow
• Paste-free dry grinding design, no polishing cream or water cooling needed during operation
• Rigorous concentricity QC testing guarantees low-vibration stable rotation

1. Material-targeted abrasive formula optimizes cutting and polishing performance for zirconia vs ceramic separately
2. Three graded grits achieve flawless mirror gloss without switching scattered single burs repeatedly
3. No paste or water cooling cuts auxiliary material costs and post-workpiece cleaning labor
4. Flexible buffer substrate minimizes ceramic crack and edge breakage to lower scrap rates
5. Compact tray packaging organizes tools tidily, boosting daily lab working efficiency and inventory management

• Three-step occlusal adjustment and high-gloss polishing for zirconia veneers, inlays, full crowns and bridges
• Dry finishing for milled zirconia blanks, no polishing paste or water cooling required

• Lithium disilicate glass ceramic and cast porcelain crown/inlay/veneer sequential trimming & bright polishing
• Occlusal adjustment polishing for metal-bonded porcelain restorations
• Post-glaze correction finishing for glazed ceramic prostheses

1. Dual kit specifications cover mainstream all-ceramic restoration categories to satisfy full lab processing demands
2. Pre-matched multi-shape assortments remove technician guesswork for step-by-step progressive finishing
3. Factory-direct pricing with flexible bulk wholesale MOQ and OEM private label tray/box customization
4. Individual piece performance inspection ensures stable batch-to-batch gloss and wear resistance
5. Fast production lead time and dedicated cross-border after-sales technical support for independent store merchants
