The main materials used in dental implant kits are pure titanium, titanium alloy, and zirconia. Pure titanium is currently the most popular choice due to its excellent biocompatibility and mechanical strength, allowing for stable osseointegration with the jawbone.
1. Implants (Artificial Tooth Roots)
Pure Titanium: Grade IV pure titanium is the most commonly used material in clinical practice. It is corrosion-resistant, has moderate strength, and is suitable for most patients. Grade IV pure titanium systems manufactured in Germany (such as General Implants) demonstrate good stability.
Titanium Alloy: Adding elements such as aluminum and vanadium to pure titanium improves strength and wear resistance, making it suitable for situations where the posterior teeth bear greater occlusal forces.
Zirconium Oxide: A ceramic material with a natural color, suitable for aesthetic restorations of anterior teeth, but it is relatively brittle and prone to chipping.
2. Abutment (Connecting Part) Materials include pure titanium, titanium alloy, or all-ceramic: Titanium abutments offer high strength and are suitable for areas with high functional requirements; All-ceramic abutments offer good aesthetics and are often used in the anterior region to prevent the metallic color from showing through the gums.
3. Crown (Visible Part)
All-ceramic crowns: Made of zirconia or lithium disilicate, they offer excellent translucency and realistic color, making them the aesthetic first choice;
Porcelain-fused-to-metal crowns: The inner layer is metal (such as cobalt-chromium alloy), and the outer layer is sintered porcelain powder, balancing strength and aesthetics;
Metal crowns: Mostly used for posterior teeth, using gold-platinum alloy or cobalt-chromium alloy, they offer high wear resistance but poor aesthetics.
