The crown of a dental implant can be either porcelain or all-porcelain. A dental implant consists of three parts: the implant, the abutment and the crown, which is mainly a pure titanium implant nail placed into the jawbone to replace the missing tooth root, and then utilizes the abutment, which connects the implant to the crown. The type of crown can be either porcelain or all-ceramic. Dental implants are one of the preferred ways of restoring missing teeth, especially in patients with terminal loss. For the crowns of dental implants it is recommended that patients who are financially well off choose all-ceramic teeth, which are aesthetically pleasing and have no metal inner crowns to interfere with MRIs. Patients can choose according to their own financial situation. Maintenance of oral hygiene is one of the key factors in preventing tooth loss, it is recommended to brush teeth in the morning and evening, rinse after meals, and have regular cleanings every 6 to 12 months.
