End of articular process growth occurs in which age range?

• A. 10-12 years
• B. 12-14 years
• C. 18-21 years
• D. 6-8 years

Answer: (C)

Growth at the temporomandibular joint’s condyle drives most remaining mandibular development, and that growth continues through late adolescence. The activity of the condylar cartilage gradually tapers off and the growth center fuses as you move into adulthood. Because this process typically finishes in late teens to early twenties, the end of articular process growth is best matched to about 18–21 years. In contrast, the younger age ranges involve ongoing growth, so they’re not correct. While females often complete a bit earlier and males a bit later, the 18–21 window captures the general finishing point for most individuals.
