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.

Here are some important excerpts from these articles.

General Guidelines for Orthodontic Retention Protocol

As a continuation of the discussion we had today, I looked up some papers related to retention and it appears that no solid evidence is available up to date. The reason I believe is ofcourse the lack of well conducted trials and the huge variability in selecting the protocols among orthodontists.

Surgery First Approach

Surgery First Approach

Dear all,

I wanted to share this article discussing this approach which is a systematic review.

In summary:

As we are all aware of its limitations and of the importance of case selection, the two major advantages for this approach are:

1- The immediate facial and esthetic improvement which is reflected on the patient’s psychological status.

2- The accelerated postoperative tooth movement as explained by the “RAP” phenomenon.

I also wanted to add some selection criteria for this approach which were mentioned by the maxillofacial team in our school:

1- Class III

2- No crowding

3- Flat curve of Spee

Have a great weekend!
