In some people this change is so strong that they noticed a marked change in their bite, Lars Bonde, Mark explains the University of Malmo. "It's good to know that this is quite normal," said the researcher. Dentists should consider this process in the treatment planning.

 

The Swedish study began in 1949. At that time, was taken in 30 young dentists and dentists a denture impression. The procedure was repeated every ten years, most recently in 1989 with at least another 18 participants. None of them had temporarily lost teeth or had been treated orthodontically. Regardless of the movement, there was – particularly in the lower jaw.

 

Over the decades, the length of the arch took a corner from the rearmost molar and incisors to the molars on the other side by up to 0.9 millimeters, the researchers estimated. By the jaw was narrow, revolved mainly the front teeth or moved forward or backward out of the ideal range.

 

The change was manifested irrespective of the presence of wisdom teeth, Bonde, Mark continues. Probably it is determined by a variety of factors. For dentists stems from the fact a real challenge, going around when it comes to dentures. "We are working against nature. Therefore, it is difficult to design something completely stable. "
