Q.  My mother is nearly 90 but still quite bright and active.  She is frustrated because she can't eat with her lower denture.  Are mini implants a good alternative for her, or is she too old?

A.  Age or physical condition are not usually factors regarding the success of mini implants.  Your mother is probably a candidate for minis.  The short surgery, low cost and minimal post-op discomfort, as well as the ability to function against the new implants immediately, make this form of therapy ideal even for seniors with numerous physical ailments.  The only common age related factors that may interfere with these cases are dementia and severe osteoporosis.  Severe osteoporosis  may affect the bone density and reduce the likelihood that the implants will be successfully retained.  Dementia makes it difficult or impossible for the patient to cooperate during surgery, and may make it difficult for the patient to insert or remove the denture after surgery.
