The age of seniors varies depending on the government policy, international organizations, and businesses. Senior orthodontic patients have the characteristics that they want to treat malocclusion that has been neglected so that their natural teeth can maintain their function more stably for the rest of their lives, or they need multidisciplinary treatment to treat secondary malocclusion caused by partial tooth loss.

Oral application treatment for the decline in sleep quality due to aging is also an area that orthodontists should not miss as part of senior treatment.

The average life span of a prosthesis is known to be about 10 years. How many years of retention can we guarantee for patients who have completed orthodontic treatment? As my career as an orthodontist progresses, the patients I treated will also become seniors and continue with me. It is necessary to think about the retention that patients and orthodontists can provide benefits to each other.
