Whether dental implants are necessary for 75-year-olds should be analyzed on a case-by-case basis, taking into account the patient’s needs and his or her own health condition. Whether it is necessary for 75-year-old people to have dental implants can not be generalized, first of all, we have to consider whether the patient has the indications for dental implants, such as whether there is a demand for biting hard objects, aesthetic needs, and comfort needs, etc.; in addition, we also have to consider whether the patient has contraindications to implantation of dental implants, such as whether the patient has high blood pressure, diabetes, and other systemic diseases, the bone condition of the missing teeth area, and so on. Therefore, only after a comprehensive assessment of the indications and contraindications for dental implants can a more accurate judgment be made. It is recommended that elderly patients with missing teeth and the intention of implantation should go to professional hospitals for consultation and treatment.
