| Research Abstract |
The main aim was to evaluate the influence on occlusal contact area (OCA), maximum bite force (MBF), center of occlusal load (COL) and tooth pain after the nocturnal use of different mandibular advance appliances (MAAs) for obstructive sleep apnea therapy.
Significant difference in COL compared to baseline was disappeared more quickly with two-piece MAAs than with one-piece MAAs, after 5 and 30minutes, respectively. Comparing two MAAs, VAS score was higher in one-piece MAAs than in two-piece MAAs until 30minutes and significance was found 30minutes after removing the appliance.
In conclusion, it is shown that two-piece MPA is superior to the one-piece one in terms of the degree side effect on occlusal function.
