It is generally made of cobalt-chromium alloy, titanium alloy, precious metals (such as gold alloy), etc. Metal substrates of different materials have different characteristics. For example, cobalt-chromium alloys have higher hardness and better biocompatibility than nickel-chromium alloys. Titanium alloys have good biocompatibility and high stability. Precious metals have excellent biocompatibility, are less likely to cause allergic reactions, and are friendly to gum health.

It can simulate the color of natural teeth, with a variety of tones available for selection, ranging from light yellow to dark yellow, from slightly white to slightly gray, etc. It can be matched with other teeth in the patient's mouth to achieve an overall harmonious and beautiful effect. Personalized customization can be carried out based on the patient's tooth shape, size, and occlusal relationship, etc., to restore the normal anatomical shape of the teeth, including the length, width, and convexity of the dental crown, making the restored teeth almost indistinguishable from natural teeth in appearance

The metal base provides strong support, enabling metal-porcelain teeth to withstand greater chewing pressure, be less prone to deformation or breakage, and be suitable for restoring back teeth and tooth defects that bear greater biting forces. Both the metal substrate and the porcelain-fused-to-metal layer have good corrosion resistance, capable of withstanding the erosion of saliva, food and other substances in the mouth, and are less likely to experience discoloration or deterioration. Except for some non-precious metal materials that may cause allergic reactions, most metal-ceramic teeth have good compatibility with human tissues and generally do not cause obvious irritation or damage to the gums, oral mucosa, etc.

It is applicable to partial tooth defects caused by dental caries, trauma, wear and tear, etc. Through metal-porcelain crowns, the shape and function of teeth can be restored.

For a few cases of missing teeth, a metal-ceramic dental bridge can be used for restoration. By using the healthy teeth on both sides of the missing teeth as abutment teeth to support the porcelain teeth in the middle, the continuity and chewing function of the teeth can be restored.
