摘要
本文对51例颅颌功能紊乱(CMD)患者及10名正常人作了咀嚼运动轨迹研究。结果,正常人咀嚼环偏向于咀嚼侧,(牙合)期轨迹阳性;CMD 患者咀嚼环可以不偏向于咀嚼侧,而偏向于症状侧,疼痛较重者失去正常咀嚼环形态,(牙合)期轨迹出现率明显降低。咀嚼环形态与咬合、TMJ 和肌肉功能状况有关,检查咀嚼运动轨迹可指导临床医生作相应的治疗。
51 CMD patients and 10 normal controls have been studied for their chewing cycle by SGG.The result showedthat the normal cycle had its direction to chewing side as wellas the clear occlusal-phase.But for the patients withCMD the cycle directed to the symptom side and coincide with open-type.The occlusal-phase lost.Patients with sevi-ous pain of CMD had no repeated cycle.It is considered that occlusion,muscles and TMJ influence and control thechewing movement.Checking the chewing cycle is benifitial for the dentists to make proper treatments.
