ABSTRACT
BACKGROUND:
Maxil ofacial malformation limits the function of the mandible, produces the overload of the temporalmandibular joint leading to oral diseases.OBJECTIVE:
To measure the characteristics of mandibular movement in populations with various types of dental occlusion.METHODS:
Thirty-three volunteers (1 male and 32 females, mean age 21.71 years) meeting the inclusion criteria were enrol ed from Dalian Medical University, China and divided into four groupsnormal control (n=10), Angle’s class I, II, III malocclusion (n=10, 8, 5). The protrusion, lateral, opening motion trace of mandibular central incisor and the right mandibular first molar, and the trace from mandibular postural position to intercuspal position were measured using the mandibular kinesiograph. The features of different occlusal patterns were analyzed using SPSS 17.0 software. RESULTS ANDCONCLUSION:
In the trace of protrusion, lateral, opening and closing motion, there were significant differences in the trace of the right mandibular first molar’s Max.Slant between Angle’s class II malocclusion group and the other three groups (P0.05). These results indicate that there are differences in the trace of mandibular central incisor and the trace of the right mandibular first molar in range and speed between different occlusal patterns. We can draw a conclusion that malocclusion has effects on the direction, range and speed of mandibular movement.
