<strong>Glass PFM</strong> refers to <strong>dental crowns or bridges</strong> where <strong>a metal base is covered with glass-like porcelain</strong> (ceramic) to look like a real tooth. It combines <strong>strength (metal)</strong> with <strong>natural appearance (porcelain/glass)</strong>.</p><p>This product is mainly used in <strong>dental prosthetics</strong> (like artificial teeth), especially for patients needing <strong>tooth replacement</strong>.</p><hr><h2>⚙️ <strong>How is Glass PFM Made?</strong></h2><ol>

</ul>
</li>
<li>
<p><strong>Porcelain/Glass Layering</strong>:</p>
<ul>
<li>
<p>Over the metal frame, layers of <strong>glass-ceramic/porcelain</strong> are fused and baked at high temperatures.</p>
</li>
</ul>
</li>
<li>
<p><strong>Shaping and Coloring</strong>:</p>
<ul>
