When does midpalatal suture close ?
Upon searching the web , I found some useful articles answering this question.
It has been stated that there is quite wide variation among individuals that it ossifies at different age groups.
The amount of ossification increases in the growth spurt ( approximately 12-13 years in females , 14-15 years in males) leading to some obliteration at the suture.
There is evidence of continuous ossification in later ages upto 20s (young adults) and even to later age in other studies reaching 32 years! showing marked degree of closure.
The importance of this point lies in whether we can use rapid palatal expansion in adults or not to achieve an opening in the midpalatal suture.Several papers showed clinical cases that palatal sutures were opened in late teens and early twenties.
The following links are of valuable articles I found useful for our discussion.
