You know the drill: scan it, design it in CAD, mill it out. But there&rsquo;s a catch. Once that piece comes off the mill, it isn&rsquo;t actually &ldquo;finished.&rdquo; There&rsquo;s a gap between a milled blank and a restoration that&rsquo;s actually ready for a patient. That&rsquo;s where infrared (IR) light comes in. Think of it as the thermal glue that holds the whole process together.</p> <h2 id="why-uv-isnt-enough">Why UV isn&rsquo;t enough</h2> <p>Most of us are used to UV light for curing. It’s fine for the surface, but UV has a hard time getting deep into thick resin or ceramic. It just doesn&rsquo;t penetrate. IR is different. It uses longer wavelengths that actually sink into the core of the material. It’s not just about heat; it&rsquo;s about triggering that secondary polymerization and shaking out the internal stress left over from the milling process. It makes the piece feel solid, not just &ldquo;cured on the outside.&rdquo;</p>
