In fact, dental implant surgery is not complicated. The simple steps are incision of the breast, drilling of the alveolar bone, placement of the implant, installation of the prosthetic cap, cleaning of the prosthetic cap, installation of the prosthetic abutment, installation of dentures, and completion of dental implants. Dental implantation is a technical job, and only experienced dentists can perform the surgery. The development of oral digitization (CAD/CAM technology, oral scanning technology, CBCT digital means) gradually provides doctors with more technical support, and also provides doctors with more technical support. Providing more technical support provides patients with more comprehensive treatment plans and better treatment processes, which has become a new trend in the development of dental implant surgery.
Dental implants are divided into three parts: implant, abutment, and crown. The ideal implant material should have safety properties such as non-toxicity, non-allergenicity, non-carcinogenicity and teratogenicity, and should also have good biocompatibility, corrosion resistance, wear resistance, mechanical properties and other properties. Implants currently on the market are generally made of pure titanium and titanium alloy materials, including grade 4 pure titanium (Swiss ITI implants, Korean Denton implants, etc.), grade 5 titanium (American Jiemei implants, French Android implants, etc.) etc.), fourth-grade cold-worked titanium (Swedish Nobel, etc.), Ti-6Al-4V titanium alloy and titanium-zirconium alloy (Swiss ITI Rui-zirconium-titanium-zirconium alloy implant), etc. The clinical application time of titanium-zirconium alloy is short, and it is only used in a few imported products. Research on titanium metal replacing traditional precious metals as new implant materials can be traced back to the 1960s. Professor Brånemark created a new osseointegration theory (that is, a strong, durable and direct relationship between the living bone tissue of the human body and titanium implants. combination). The establishment of this theory set off revolutionary changes in the field of implants and laid the foundation for modern oral implantology. Brånemark subsequently introduced threaded screw implants made of pure titanium (99.7%) in the late 1970s. The use of titanium in implants is due to its high corrosion resistance, mainly due to the inert and tough titanium dioxide (TiO2) passivation film that covers the metal surface.
