The abutment is an auxiliary device for the implant in dental restoration. After the implant is implanted, the abutment will also be permanently attached to the implant through the operation.
The abutment extends to the outside of the gum to form a transgingival component, which is used to fix dentures and other orthodontics (restorations). The use of an abutment is not required if the implant itself contains a complete transgingival part.
Implant material:
Ceramic materials: including bio-inert ceramics, bio-active ceramics, bio-degradable ceramics, etc. It has the characteristics of high mechanical strength, corrosion resistance, no irritation and toxicity, and histocompatibility. It is also used clinically.
Carbon materials: including glassy carbon, low temperature isotropic carbon, etc. The advantage is that it has high stability in vivo and no biodegradation.
Metal and alloy materials: including gold, 316L stainless steel (iron-chromium-nickel alloy), cast cobalt-chromium alloy, titanium and alloys, etc. Its advantages are high strength and good rigidity, but poor biomechanical adaptability and tissue and bone adaptability.
