17: Prominent chin and TMJDS

17 Prominent chin and TMJDS


Jocelyn, aged 23, is referred by her general dental practitioner because of her prominent chin (Fig. 17.1) and pain in her left temporomandibular joint (TMJ). What are the causes and how would you manage these problems?


History of complaint

Jocelyn has been more aware of her prominent chin and her bite since she was in her last year at school. After consultation with an orthodontist at age 12, she had two upper teeth removed to provide space for the upper eye teeth (she had both lower first permanent molars extracted at age 8 because of decay.) She did not wear any braces on her teeth. She was advised to wait until she was in her late teens to have the bite of her front teeth reassessed. In the past 6 months she has become quite self-conscious about her facial appearance, although she feels that her chin does not appear to have become more prominent in the past 4 years.


Intraoral examination

The intraoral views are shown in Figure 17.2.
