Delivery systems
The A-dec 300 Traditional and Continental delivery systems can seamlessly incorporate a quad-volt intraoral light source along with two clinical devices.

Dental lights
A-dec LED dental lights significantly enhance your practice by providing a clearer view of tooth surfaces, minimizing eyestrain, and reducing fatigue. Opt for either the A-dec 500 LED dental light or the A-dec 300 LED dental light to experience these benefits.

Monitor mounts
Monitor mounts are designed to pivot, allowing for optimal viewing from various patient positions. By integrating an intraoral camera with a chairside monitor, you can significantly boost case acceptance.
A cabinet-mounted monitor positioned at 12 o’clock is a superb option for managing patient records and practice administration. Monitors mounted on ceilings, walls, or central/side cabinets are perfect for delivering patient entertainment, whether they’re seated or lying down.

Assistant’s instrumentation
Position the assistant’s clinical devices exactly where they are most essential with the A-dec 300 assistant’s instrumentation.
Choose from adjustable 3- or 4-position holders that can be mounted on the chair, cuspidor, or telescoping arm for optimal convenience and accessibility.

Cuspidor
This glass bowl features a built-in screen and offers both manual and timed adjustable settings for cup filling and bowl rinsing. Support center assistance is required for optimal performance.

A-dec 300 Continental delivery system
The ergonomic Continental design minimizes the weight and strain of the tubing, providing exceptional comfort whenever you sit down to work.

A-dec 300 Traditional delivery system
Whether you choose a specific left/right delivery or the ambidextrous Radius configuration, the A-dec Traditional delivery system ensures that your handpieces and accessories are always easily accessible.
