Why Proper Polishing Matters for Zirconia

A finely polished surface on Advance Zirconia Crowns not only delivers that “just-polished” shine patients love but also minimizes wear on opposing teeth, reduces plaque retention, and preserves margin integrity.

Inconsistent or inadequate polishing can introduce micro-scratches that harbor bacteria and accelerate wear — compromising both form and function in your dental lab restorations.

Risks of Inadequate Surface Finish

  • Increased Opposing-Tooth Wear
     Rough zirconia can abrade enamel, leading to sensitivity and unexpected remakes.
  • Plaque Accumulation
     Micro-grooves provide niches for bacterial adhesion, raising the risk of peri-margin inflammation.
  • Loss of Translucency
     Surface irregularities scatter light, dulling the natural translucency of multi-layered zirconia.

Step-by-Step Polishing Workflow

Coarse Rough-Out

  • Use a medium-grit (120–150 µm) zirconia polisher at 8,000–10,000 RPM to refine major adjustments.

Intermediate Smoothing

  • Switch to fine-grit (30–60 µm) polishers for 20–30 seconds per surface, maintaining light pressure.

High-Gloss Finishing

  • Employ diamond or silicone-based polishers (10–20 µm) at 12,000 RPM in a wet environment to achieve a mirror-like sheen.

Final Inspection

  • Under 10× magnification, verify no visible scratches and confirm uniform gloss across occlusal, axial, and margin areas.

Chairside vs. Lab Polishing Kits

Chairside Kits

  • Portable, with three-step burs and polishers for quick intraoral touch-ups after adjustments.

Lab Kits

  • Comprehensive handpiece-mounted wheels, pastes, and brushes for full-surface finishing before shipment.

Choose the kit that aligns with your workflow: immediate patient appointments versus pre-delivery lab finishing.

Checking Surface Roughness and Gloss

Surface Roughness (Ra)

  • Aim for an Ra of < 0.2 µm, measurable with simple test strips or profilometers.

Gloss Meter

  • A handheld gloss meter reading > 60 GU (gloss units) confirms a high-shine finish consistent with natural enamel.

These quick checks ensure every Advance Dental Export zirconia restoration leaves your lab ready for clinical success.

Frequently Asked Questions

Q: Can I repolish in-office after occlusal adjustments?
 A: Yes. Use a three-step chairside polishing kit immediately after adjustments to restore gloss and prevent surface damage.

Q: Which polisher works best on multi-layered zirconia?
 A: A diamond-impregnated, silicone-based polisher (10–20 µm) preserves color gradients while achieving high shine.

Key Takeaways

  • Proper Polishing extends crown longevity, protects opposing teeth, and maintains esthetic translucency.
  • Three-Step Workflow — coarse rough-out, intermediate smoothing, high-gloss finish — delivers consistent results.
  • Surface Metrics (Ra < 0.2 µm, gloss > 60 GU) provide objective quality control.
  • Right Kit Choice ensures efficient chairside touch-ups or lab-grade finishing.

How has medical cannabis helped your life?

  Medical cannabis has provided effective relief without the harsh side effects of opioids. People suffering from anxiety, PTSD, or depression have found cannabis especially CBD-rich formulations to help calm the mind, reduce intrusive thoughts, and promote emotional balance, often when traditional medications failed or caused adverse effects. Cancer patients have used cannabis to manage chemotherapy-induced nausea, stimulate appetite, and relieve pain, improving their strength and outlook during grueling treatments. Medical cannabis has shown remarkable results in reducing seizure frequency and severity. These improvements often lead to a greater sense of autonomy, peace, and hope. Medical cannabis empowers individuals to reclaim control over their health, blending nature with science in a way that respects both the body’s complexity and the power of plant-based healing offering more than just symptom relief, but a renewed sense of life.  Read more……

What’s the difference between CBD and medical marijuana?

  The difference between CBD and medical marijuana lies primarily in their composition, effects, and legal classification, and at   Greenlight Wellness Export , we help patients understand these distinctions to make informed health decisions. CBD , is a non-psychoactive compound found in the cannabis plant, meaning it does not produce the “high” commonly associated with marijuana. It is typically derived from  hemp , a variety of cannabis with low THC (tetrahydrocannabinol) content, and is used to manage conditions like anxiety, inflammation, epilepsy, and chronic pain without altering mental clarity. Medical marijuana , on the other hand, refers to the use of the whole cannabis plant or its extracts — including THC and CBD for therapeutic purposes. THC is the psychoactive component that can alter perception and mood, and in medical marijuana, the THC content is higher to treat conditions such as severe pain, nausea from chemotherapy, muscle spasms, and loss of appetite i...
