At Grishin Denture Specialist in Spokane, WA, every step of denture fabrication and adjustment is performed with uncompromising attention to safety and cleanliness. Behind every comfortable smile lies a meticulous sterilization process—one designed to protect patients from bacteria, cross-contamination, and infection, while ensuring a flawless final product.

Why Denture Lab Hygiene Matters

The quality of a denture is more than its aesthetics—it’s the result of disciplined lab practices. Every impression, model, and appliance passes through multiple hands and surfaces before completion. Without proper sterilization, these steps could introduce harmful microorganisms that survive in porous materials like acrylic, wax, or stone.

At Grishin Denture Specialist, we follow strict CDC and ADA sterilization guidelines using:

Autoclave sterilization for all reusable metal instruments
Cold sterilant for heat-sensitive tools
Ultrasonic cleaning units to remove micro-debris from burs, trays, and polishing equipment
Barrier techniques that prevent lab cross-contamination during fabrication and polishing

This multi-layered system keeps each patient’s case isolated, ensuring their dentures are built in a clean, safe environment from start to finish.

Disinfection of Impressions and Models

Impressions are the foundation of every successful denture. At our Spokane denture clinic, every alginate impression—taken using traditional methods for superior accuracy—is disinfected immediately before being poured into stone. This eliminates bacterial transfer while preserving surface detail.

Our lab uses EPA-approved disinfectants compatible with alginate, ensuring accuracy isn’t sacrificed for safety. Because we rely on traditional impression techniques rather than digital scans, our process maintains precise definition and allows hands-on control over every surface.

Safe Handling of Acrylic and Polishing Equipment

During finishing and polishing, denture bases are exposed to fine acrylic dust—a material that, if not contained, can affect air quality and contaminate tools. Our in-house lab uses high-filtration vacuums, dedicated work zones, and disposable pumice trays to prevent crossover between cases.

All polishing compounds are refreshed between patients, and final dentures undergo a secondary disinfection bath before delivery. These extra steps ensure the dentures you receive are not only comfortable and natural-looking but also microbiologically clean.

Protecting Patients and Staff Alike

Cleanliness in the lab goes hand in hand with safety for our staff and community. Each team member follows PPE protocols including masks, gloves, and eyewear, and every workstation is disinfected before and after case handling.

We also use biological spore testing to verify autoclave efficiency—ensuring sterilization cycles reach the required temperature and pressure to neutralize all microorganisms. These validation steps separate a precision lab from a basic one, guaranteeing Spokane patients receive safe, premium-quality dentures.

Why Traditional Methods Still Win in Quality Control

While some clinics rely on mass-produced or outsourced digital dentures, our Spokane denture lab maintains full control through traditional craftsmanship. Using alginate impressions and hand-layered acrylics allows us to inspect, disinfect, and perfect every denture personally. This attention to hygiene and precision creates results that are both safer and more natural-feeling than automated production can achieve.
