The study aimed to observe changes in MyHC-I expression in the masseter muscle of Beagle dogs receiving functional appliance therapy and to investigate muscular adaptation.
Eight male Beagle dogs were divided into experimental and control groups, with samples taken at various treatment intervals and analyzed for MyHC-I expression using statistical software.
Results indicated a significant increase in MyHC-I expression in the experimental group at 4 weeks, peaking at 8 weeks, before leveling off after 16 weeks, suggesting that functional appliances can enhance muscle remodeling in the masticatory system.
