Dental CAD CAM PEEK Dental Disc

 

This PEEK disc is used in digital dental milling systems for implant abutments, frameworks, temporary bridges, custom trays, and night guards. It fits long-term temporary and semi-permanent restorations in modern dental labs.

 

Medical-grade PEEK (polyetheretherketone) is used as the base material. It is a high-performance polymer with stable physical and chemical properties.

High purity medical-grade resin

Stable performance under long-term oral conditions

Biologically inert material with low allergenic risk

Compatible with soft tissue and bone integration

Uniform molecular structure for consistent machining behavior

Key Material Characteristics
Density: lightweight compared with metal alloys
Elastic modulus: lower than metal, closer to natural dentin behavior
Wear resistance: similar to metal alloy performance
Radiolucent: allows X-ray penetration without image interference
Color stability: resistant to discoloration in oral environment
Biocompatibility: supports long-term intraoral use with low immune response risk
Processing Advantages
Easy milling with CAD/CAM systems
Stable cutting performance during CNC processing
Suitable for precise shaping of complex dental structures
Low internal stress reduces deformation during machining
Manufacturing Process

1. Raw material preparation
Medical-grade PEEK particles are selected and weighed under controlled conditions. Small amounts of stabilizers may be added to improve thermal and processing stability.

2. Melt extrusion forming
PEEK is melted at high temperature and extruded into flat sheets. Flow rate and temperature are controlled to keep the internal structure uniform.

3. Heat treatment / annealing
The formed sheets undergo heat treatment to release internal stress and improve crystallinity. This improves dimensional stability and mechanical strength.

4. CNC milling (CAD/CAM process)
After annealing, the sheets are cut and milled using CAD/CAM systems into disc shapes. Allowance is adjusted to compensate for processing shrinkage.

5. Surface finishing and inspection
The surface is polished to remove burrs and ensure smoothness. Each disc is checked for size accuracy, mechanical performance, and biocompatibility before packaging.
