Which size range has a posterior condylar thickness of 11.5 mm?

Which size range has a posterior condylar thickness of 11.5 mm?

• A. 2-6
• B. 5-7
• C. 7-8
• D. 8-9

Answer: (C)

Posterior condylar thickness increases with size, so you use the reference chart to map a measurement to the corresponding size range. An 11.5 mm thickness sits in the middle portion of that chart, which matches the middle option among the four given. The smallest size ranges yield thinner values than 11.5 mm, while the largest size ranges yield thicker values, so they wouldn’t equal 11.5 mm.
