1.Healthy teeth can be completely preserved without grinding the neighboring healthy teeth. 2, solid artificial tooth roots (implant denture through the retention device on the abutment, the upper denture will be fixed, there is a good retention and stabilization effect) can increase the sense of comfort (implant denture abutment is small or no abutment), there is a very good masticatory force (wearing implant denture in the exercise of masticatory functions, the dental force through the implant directly to the jawbone or the jawbone, the force will soon be conduction and dispersed to the larger supporting bone), feel like their own natural teeth. When patients exercise chewing function, the force is transmitted directly to the jawbone or jawbone through the implant, and the force is quickly transmitted and dispersed to the larger supporting bone (which is able to withstand the larger dentition force), and the feeling is just like one’s own natural teeth. The stability of dental implants will not be like the ordinary movable dentures that may fall off during eating or talking, causing the danger of blocking the trachea or esophagus. 4, the artificial tooth root is deeply planted in the alveolar bone, there is functional stimulation of the alveolar bone, can protect the alveolar bone structure, to avoid its atrophy. 5, Artificial dental implants can have a long life. 6.Aesthetic appearance, just like natural teeth, facial expression when you speak is as natural as the original, increase your self-confidence.
