Compared with traditional restorative methods (movable trays and fixed bridges), implant dentures have the following advantages: 1) no need to wear down adjacent real teeth; 2) if more teeth are missing or even when the mouth is completely edentulous, dental implants can still provide you with comfortable and stable dentures; 3) effectively preventing the alveolar bone from continuing to atrophy after the loss of teeth; 4) excellent solidity; 5) maximizing the restoration of masticatory function; and 6) aesthetics and lifelike effect. Jaw bone tissue has a benign compensatory response to appropriate loads, while the stresses generated by excessive loads cause bone tissue resorption. After traditional dentures are put in, the burden on the abutment teeth and mucosal tissues is generated, and if this burden is too heavy, the abutment teeth will be fractured, loosened and the jawbone tissues will be resorbed. Oral implants are supported by the jawbone tissue in the missing tooth area, thus not burdening the remaining teeth and preventing the resorption of the jawbone tissue. In terms of chewing, swallowing, pronunciation and other functions, dental implants have strength and comfort comparable to natural teeth. Psychologically, young people are sometimes resistant to dental implants, and oral implants should be a better choice at this time.
