New Product Launch
Dian Fong Abrasives introduces a 2-in-1 pre-sintered zirconia polisher series for dental laboratories. Designed for zirconia crowns, bridges, and frameworks before sintering, the series supports contour shaping, surface smoothing, and pre-polishing in CAD/CAM dental lab workflows.
Why Pre-sintered Zirconia Requires Controlled Finishing
Pre-sintered zirconia, also known as green-state zirconia, is easier to adjust than fully sintered zirconia. However, this stage also requires controlled pressure and suitable finishing instruments. Aggressive grinding or unsuitable tools may create uneven surfaces, over-reduced margins, or additional post-sintering correction work.
In a conventional zirconia workflow, technicians may use separate tools for material removal, contour adjustment, and surface preparation. For dental laboratories that process crowns, bridges, and frameworks repeatedly, these tool changes can slow down production and make the finishing process less efficient.
The Dian Fong 2-in-1 Pre-sintered Zirconia Polisher is designed to simplify this workflow by combining shaping and pre-polishing into one practical finishing solution for use before zirconia sintering.
Product Overview
The Dian Fong 2-in-1 Pre-sintered Zirconia Polisher is a silicone-bonded alumina abrasive polisher series developed for dental lab zirconia finishing applications. It is intended for use after milling and before final sintering, especially when technicians need to refine zirconia restorations efficiently and consistently.

Key Features
Two-in-one workflow for shaping and pre-polishing
The series is designed to help technicians complete contour adjustment and initial surface refinement in a simplified workflow. This reduces the need to switch between multiple finishing instruments during pre-sintered zirconia processing.
Silicone bond for flexible surface contact
The silicone-bonded structure provides flexible contact with zirconia surfaces. This is useful when working on crowns, bridges, frameworks, connectors, margins, and curved surfaces where controlled pressure is important.
Alumina abrasive for zirconia surface preparation
Alumina abrasive supports controlled grinding and surface smoothing on pre-sintered zirconia. It is suitable for surface preparation before final sintering and helps create a more manageable finishing condition for the next stage.
Medium and fine grit options
The dark grey medium grit option supports efficient material removal and contour adjustment. The white fine grit options support controlled finishing and pre-polishing for smoother surface preparation.
Workflow Benefits for Dental Laboratories
Fewer tool changes
By combining shaping and pre-polishing into a more efficient workflow, the series helps reduce the number of tool changes required during green-state zirconia finishing.
More consistent surface preparation
The flexible silicone bond and controlled abrasive action help technicians prepare zirconia surfaces more predictably before sintering.
Simplified inventory and operation
For laboratories and distributors, a focused zirconia finishing series can make product selection easier and reduce workflow complexity compared with using multiple unrelated tools.
Clear distributor positioning
The series has a direct commercial message: a zirconia-focused finishing solution for CAD/CAM dental laboratories that need practical tools for pre-sintering adjustment.
Recommended Applications
The Dian Fong 2-in-1 Pre-sintered Zirconia Polisher series is suitable for common dental lab zirconia finishing tasks before sintering.
- Pre-sintering adjustment of zirconia crowns
