Where wrinkles, frown lines, and loss of skin tone are evidence of facial aging, aging of the dentition is characterized by generalized recession, loss of alveolar bone height and loss of tooth alignment.1,2 Approximately two-thirds of untreated adolescents with normal occlusions will develop incisor irregularity by early adulthood as a result of changes in the mandibular arch.2-4 Mandibular incisor crowding typically occurs into the fifth decade and potentially throughout life.5,6 Mandibular arch changes in an orthodontically treated dentition are dynamic and constantly changing; mandibular incisor crowding may reappear over time particularly in the absence of lifelong retention.7

There is a growing trend in anti-aging techniques. The increased prevalence of elective cosmetic techniques reflects the public's desire for an appearance of youth and a growing acceptance of the procedures associated with this trend. Since 1997, the prevalence of surgical procedures and nonsurgical procedures has increased 114% and 754% respectively.8

Dental treatment is arguably the most accepted method of basic cosmetic enhancement. Orthodontic treatment has been a long-standing solution to a compromised dentition. Once reserved mainly for children, more adults continue to seek treatment as they increase their presence in specialty practice.

Various options exist to address mandibular incisor crowding including metal or ceramic fixed labial appliances, spring retainers, and other traditional removable appliances, lingual fixed appliances, and clear removable aligners such as Invisalign™.
