Until what age does the palatal suture contribute to maxillary growth?

• A. 12 years
• B. 15 years
• C. 18 years
• D. 21 years

Answer: (D)

The palatal (midpalatal) suture acts as a growth site that allows transverse widening of the maxilla during development. Its capacity to contribute to skeletal expansion fades as the suture gradually fuses with age. By about 21 years, fusion is typically complete, so further maxillary growth from sutural widening becomes unlikely. In younger patients, rapid maxillary expansion can achieve skeletal changes through this suture, but in someone around 21, the sutural contribution is largely exhausted, and any additional changes would rely more on dental movement or surgical-assisted approaches if expansion is still needed. Individual variation exists, but 21 years is the period when the sutural growth contribution is generally considered to end.
