There are many dental implant materials, patients can choose the appropriate dental implant material according to their own situation, under the guidance of the doctor, and there is no such thing as a good dental implant. There are four types of dental implant materials commonly used in clinical practice. The first is metal and alloy materials, including gold, 316L stainless steel, cast cobalt-chromium alloy, titanium and alloys. The second is the category of carbon materials, including glassy carbon, low-temperature isotropic carbon, and so on. The third is the category of ceramic materials, including bio-inert ceramics, bio-active ceramics, biodegradable ceramics and so on. The fourth is the category of polymer materials, including acrylates, PTFE, etc. However, nowadays, more metal is used mainly pure titanium and titanium alloy, and ceramics include bioactive ceramics and some composite materials. Each patient’s specific situation is different, the material chosen will also be different.
