2-in-1 Pre-sintered Zirconia Polisher for Dental Lab Finishing
Shape and pre-polish green-state zirconia restorations before sintering with Dian Fong’s silicone-bonded alumina polisher series.
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 helps simplify shaping, surface smoothing, and pre-polishing in CAD/CAM lab workflows.
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. The three models share the same abrasive concept and are differentiated by shape and size only.
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.
Three shape options for different working areas
The three models are offered to match different restoration shapes, surface areas, and access conditions. They share the same abrasive specification; the practical difference is external shape and size.
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
A focused series with shape-based model selection makes it easier for laboratories and distributors to match the tool to the working area.
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
- Surface preparation of zirconia bridges
- Framework contour refinement before sintering
- Post-milling support and sprue removal
- Margin and connector adjustment
- CAD/CAM dental laboratory zirconia workflow
Technical Specifications
The following models are available for pre-sintered zirconia finishing and pre-polishing. All models use a silicone bond with alumina abrasive and are recommended for operation at 4,000-7,000 rpm. Model selection is based on shape and size.
| Model | Size D x L / mm | Bond | Abrasive | Model Difference | Recommended Speed |
|---|---|---|---|---|---|
| BWG507-100MF | 10 x 26 | Silicone | Alumina | Larger external shape for broader surface contact | 4,000-7,000 rpm |
| BWG243-100MF | 7 x 19 | Silicone | Alumina | Standard external shape for general finishing access | 4,000-7,000 rpm |
| BWG243-060MF | 6 x 16 | Silicone | Alumina | Compact external shape for smaller or more detailed areas | 4,000-7,000 rpm |
Model Selection Guide
Different models can be selected according to restoration shape, access space, and surface area. The series should be presented as one abrasive specification with three external shape options.
| Model | Suggested Use |
|---|---|
| BWG507-100MF | Suitable for broader contour adjustment and larger surface areas where a larger contact shape is useful. |
| BWG243-100MF | Suitable for general zirconia finishing on crowns, bridges, and frameworks where a balanced working shape is preferred. |
| BWG243-060MF | Suitable for smaller access areas, detailed contour refinement, and more delicate surface preparation where a compact shape is required. |
