For the doctor, the posterior teeth are mainly to restore the patient’s chewing function, while the anterior teeth are mainly to restore the aesthetics. Since eating depends on the posterior teeth to chew, the posterior teeth are generally considered to be as thick as possible to restore the gingival papillae to prevent food ingrowth. In addition, because there is a difference between natural teeth and dental implants, that is, natural teeth have periodontal membrane while dental implants do not have periodontal membrane. After the restoration of the implant denture, the natural teeth will have a competing physiological process of movement, but the implant teeth do not, so the gap between the implant teeth and the natural teeth will easily appear and cause food impaction. For the anterior teeth, it is mainly related to the aesthetics, because the front teeth are the ones that are exposed when talking or eating. Therefore, we should pay special attention to the aesthetics when implanting anterior teeth, paying attention to the height of the patient’s smile line, the shape of the crown, the fullness of the upper lip, and the distance from the gum papilla to the crown root.
