Dental implants are a very popular procedure, but like many other procedures, they are not available to everyone. Dental implants are performed on people of all ages, so it can be performed on a 60-year-old or a 95-year-old. On the other hand, a fully formed jawbone is essential for dental implant placement, so other methods of restoring the teeth are suggested for those aged under 16 or 17 years. Dental implants are basically a minor operation, but in some cases they cannot be performed. Dental implants are also not threaded during pregnancy, when the patient has no dental cleanings, when the patient has oncological diseases and is undergoing chemotherapy or irradiation, or when he or she is taking a certain group of bisphosphonate drugs for osteoporosis, which of course can be implanted in most cases once the condition has passed. Immune system disorders, allergies to the materials used in the implantation process and poorly controlled diabetes mellitus may also be contraindications. Acute infectious and systemic diseases are also incompatible with implant placement, but can be treated with implant-supported dentures.
