Keystone Procure 300 Light Oven: Curing Custom Trays and Light-Cure Resins
The Keystone Procure 300 Light Oven is a lab curing unit that hardens light-cure custom trays, base plates and other light-cure resins with two halogen bulbs, a reflective chamber and a rotating glass platform. Chase Dental Supply carries the Procure 300 from Keystone Industries both on its own and with a sample pack, and this guide explains how it works and where it fits in your lab.
Quick Answer
The Keystone Procure 300 Light Oven is a third generation light curing unit for dental labs. Two halogen bulbs, a highly reflective chamber and a rotating glass platform give uniform light coverage and good depth of cure, while a built-in fan maintains temperature to eliminate warping. It is used to cure light-cure resins such as custom tray and base plate materials.
Key Takeaways
- The Procure 300 is a third generation light curing unit designed for high light intensity without negative heat build up.
- Two halogen bulbs provide intensity and depth of cure, and a highly reflective chamber spreads the light evenly.
- A rotating glass platform turns the appliance for uniform light exposure on every surface.
- A built-in fan maintains optimum temperature to eliminate warping.
- It is available on its own (#9634590) or with a sample pack (#9634600).
What Is the Keystone Procure 300 Light Oven?
The Keystone Procure 300 Light Oven is an advanced third generation light curing unit built to give superior lighting intensity and excellent depth of cure. Keystone designed it to deliver maximum light intensity without the negative heat build up that can distort appliances.
A light curing oven is an enclosed lab unit that polymerizes light-activated dental resins by exposing them to high-intensity light from all sides. It is different from a handheld chairside curing light, which cures small restorations in the mouth.
If you are comparing chairside units, our TPC LED curing lights guide covers cordless curing lights and radiometers for the operatory.
How Does the Procure 300 Cure Light-Cure Resins?
The Procure 300 cures resin by surrounding the appliance with intense halogen light while a rotating platform and reflective chamber keep exposure even. A built-in fan controls temperature so the appliance cures without warping.
Two halogen bulbs
Two powerful halogen bulbs provide excellent intensity and depth of cure. That matters for thicker light-cure tray and base plate resins, which need light to reach through the material.
Reflective chamber and rotating glass platform
The highly reflective chamber bounces light back onto the appliance for uniform coverage. A rotating glass platform turns the work during the cycle so light reaches the appliance evenly from all sides.
Built-in cooling fan
The built-in fan maintains an optimum temperature inside the unit. Keystone states that this temperature control eliminates warping, which protects the fit of custom trays and base plates.

Procure 300 vs Procure 300 with Sample Pack: Which Should I Buy?
Both listings describe the same Procure 300 curing unit and features. The difference is that #9634600 includes a sample pack, which is convenient for labs getting started with light-cure work.
| Listing | Item number | What you get | Best for |
|---|---|---|---|
| Keystone Procure 300 Light Oven | #9634590 | Procure 300 light curing unit | Labs that already stock their light-cure resins |
| Procure 300 Light Oven with Sample Pack | #9634600 | Procure 300 light curing unit plus a sample pack | Labs setting up light-cure work for the first time |
Availability on these units can change with the manufacturer. Call Chase Dental Supply at 888-548-7582 to confirm status before you plan around a delivery date.
Who Should Use a Light Curing Oven?
A light curing oven makes sense for any dental lab, dental school or in-house practice lab that works with light-cure resins on a regular basis. It keeps curing consistent from case to case instead of depending on a handheld light.
- Full-service dental labs that fabricate custom impression trays and record bases for dentists.
- Denture and removable labs that use light-cure base plate and tray resins in their daily workflow.
- Dental schools and teaching labs that want a predictable, enclosed curing process for students.
- Larger practices with an in-house lab that make their own custom trays.
Light-Cure Custom Trays vs Vacuum Formed Trays: What’s the Difference?
Light-cure trays are adapted by hand from resin and cured in a unit like the Procure 300, while vacuum formed trays are made by heating a thermoplastic sheet over the model. Both produce custom impression trays, so the choice usually comes down to workflow and equipment.
Light-cure tray workflow
With light-cure resin, the technician adapts the material over a model with relief, adds a handle, and cures it in the oven. Always follow the resin manufacturer’s instructions for cure time and compatibility with halogen light curing units.
Vacuum formed tray workflow
For thermoformed trays, Keystone Tray Material is pure, high impact styrene in .125 or .150 thickness, formed on a vacuum former such as the Keystone Machine III Vacuum Former. Our Keystone tray, retainer and spacer sheet guide explains which thickness to choose.
Keystone Spacer Foam works as reusable relief in either workflow, since one size works for all materials. For denture bases and wax bite plates, Keystone Base Plate Material offers .060, .080 and .100 high impact styrene with a low melt temperature.
Labs that do both often trim thermoformed trays with the Pro-Form Electric Knife. To compare forming machines, see our Keystone vacuum former buyer's guide.

Frequently Asked Questions
What is the Keystone Procure 300 Light Oven?
The Keystone Procure 300 is a third generation light curing unit for the dental lab. It uses two halogen bulbs, a highly reflective chamber and a rotating glass platform for uniform light coverage, plus a built-in fan that maintains temperature to eliminate warping.
What can I cure in the Procure 300?
The Procure 300 is built for light-cure dental resins, such as light-cure custom tray and base plate materials. Always confirm that the resin you use is compatible with halogen light curing and follow the resin manufacturer’s recommended cure times.
Why does the Procure 300 have a fan?
Keystone designed the Procure 300 to deliver maximum light intensity without negative heat build up. The built-in fan maintains an optimum temperature inside the chamber, which Keystone states eliminates warping of the appliance during curing.
What is the difference between the two Procure 300 listings?
Chase Dental Supply lists the Keystone Procure 300 Light Oven by itself (#9634590) and the Procure 300 Light Oven with Sample Pack (#9634600). Both describe the same curing unit and features. Call 888-548-7582 to confirm current availability and lead time before ordering.
Should I use light-cure trays or vacuum formed trays?
Both work well, and many labs use both. Light-cure tray resin is shaped by hand and cured in a unit like the Procure 300, while vacuum formed trays use Keystone Tray Material (.125 or .150 high impact styrene) on a vacuum former with spacer foam. Choose based on your workflow, equipment and the dentist’s preference.
