Why your oral appliance material matters
If you’re dealing with snoring, sleep apnoea, teeth grinding, or jaw pain, a custom night guard can make a real difference—repositioning your jaw, easing muscle tension, and protecting your teeth. The catch? Material matters. A lot.
For years, acrylic was the standard material for oral splints, but it came with major downsides—bulky designs, frequent breakage, and difficulty with cleaning. Today, 3D Sleep’s advanced 3D printed nylon splints have transformed oral appliance therapy, offering a stronger, thinner, and more comfortable solution. With vapour polishing, these nylon splints are even better—smoother to wear, highly resistant to staining, and far more hygienic than traditional options.
Vapour polishing
Vapour polishing, also known as vapour smoothing, is a surface refinement process that uses a controlled medical-grade vapour to gently melt and reflow the outer layer of high-performance nylon splints. This seals microscopic pores, resulting in a smooth, glossy, and non-porous finish.
This technology is widely used in advanced manufacturing globally, but when it comes to dental appliances, 3D Sleep is the only lab in Australia currently offering this process. It’s the result of more than 18 months of development and integration, and it’s transforming how we deliver high-quality oral splints.
Enhancing splint quality
Unlike manual polishing, vapour polishing improves the splint without compromising its fit or structure. In fact, it makes the material even better:
- Seals the surface to prevent fluid, stain, and bacterial absorption
- Reduces surface roughness by up to 71%, eliminating the need for manual polishing
- Increases tensile strength and flexibility, reducing the risk of fractures or fatigue
- Improves longevity, especially for patients who clench or grind their teeth
What this means for you
- Ultra-smooth feel in the mouth—especially helpful for those with sensitive cheeks, gums, or tongues
- Better hygiene, as the sealed surface resists plaque buildup and reduces the risk of bad breath or infection
- Stain resistance, even with regular coffee, tea, or red wine consumption
- Sleeker look, thanks to the polished, glossier finish
- Longer-lasting durability, saving you from frequent repairs or replacements

Nylon vs. acrylic material
🚫 Bulky and uncomfortable: Needs to be thick to avoid breaking
🚫 Brittle and prone to cracking: Can pose a choking hazard if it fractures
🚫 Stain and odour-prone: Absorbs bacteria and fluids over time
🚫 Hard to clean: Rough surfaces trap debris
✅ Ultra-thin yet tough: As thin as 0.5 mm without sacrificing strength
✅ Lightweight and flexible: Comfortable for all-night wear
✅ Highly durable: Less risk of cracking, breaking, or warping
✅ Hygienic and sealed: Smooth, bacteria-resistant surface
✅ Stain-resistant and fresh: Easier to clean, preserves its original appearance longer
