ABSTRACT
Dental implant has been widely concerned “the third pair tooth” for patients with dentition defect because of its beautiful, comfortable, good chewing effect. In order to have a higher success rate of planting, how to make dental implants combined with bone better is most important [1]. The structure design of implant, manufacture, material and surface treatment are several key factors influencing the success rate [2]. However, the structure of implant is most important. It should have high strength and low damage to the surrounding bone tissues. With the rapid development of advanced material science and manufacturing technologies, numerous structure designs of the dental implants have been proposed and studied in order to resolve some remaining issues in the clinic.
