This study aimed to evaluate the duration of a reduced maximal voluntary bite force after a botulinum toxin intervention. Methods: In an intervention group, 25 units of Xeomin® (Merz Pharma GmbH & Co KGaA, Frankfurt am Main, Germany) botulinum neurotoxin type A were injected into the masseter muscles bilaterally (to a total of 50 units).
This study aimed to evaluate the duration of a reduced maximal voluntary bite force (MVBF) after a botulinum toxin intervention. Methods: In an intervention group, 25 units of Xeomin® (Merz Pharma GmbH & Co KGaA, Frankfurt am Main, Germany) botulinum neurotoxin type A were injected into the masseter muscles bilaterally (to a total of 50 units). A control group did not receive any intervention. MVBF was measured in Newtons using a strain gauge meter at the incisors and first molars. The intervention group was comprised of individuals seeking aesthetic treatment for masseter reduction (n = 20), and the control group (n = 12) comprised of volunteers.
