Primary Function

This device is designed to ensure the homogeneous and precise mixing of two separate components, such as a base and catalyst, directly within a cartridge. By eliminating manual spatulation, it provides consistent material quality, reduces the risk of air entrapment, and improves the overall reliability of the mixed material.

Clinical Applications

The dispenser is widely used with a variety of dual-component dental materials, including:

• Impression materials, such as Polyvinyl Siloxane (PVS), for accurate impressions of crowns, bridges, and other prostheses

• Self-solidifying composite or compound resins

• Dental adhesives, cements, and luting materials

Operating Mechanism

The system operates as a manual, pistol-grip mixing gun. A dual-barrel cartridge is loaded into the dispenser, and a static mixing tip is attached. When the handle is squeezed, the internal plungers push both components simultaneously through the mixing tip, where they are thoroughly blended before being dispensed smoothly and evenly.

Mixing Ratios

TPC mixing guns are available in different ratio configurations to suit various material requirements, most commonly 1:1 and 1:2 (or 2:1). These ratios refer to the volumetric proportion of the two components, ensuring accurate mixing according to the manufacturer’s specifications.

Ergonomic Design and Usability

The dispenser typically features a lightweight and ergonomic design, allowing for comfortable one-handed operation and reducing hand fatigue during clinical procedures. Many models are also designed for easy cartridge loading, simple cleaning, and in some cases are autoclavable, supporting high standards of infection control.
