生理性咬合应是肌位与牙位一致,工作侧咀嚼时,非工作侧应无接触,前伸咬合时,后牙应无接触,若肌位与牙位不调,则说明有咬合高点存在:若非工作侧有接触,则形成咬合干扰,成为口颌系统的有害因素,常是颞颌关节紊乱症的潜在病因。只有进行咬合调改才能去除这种有害因素。一、咬合调改的适应范围咬合干扰在人群中普遍存在,但并非所有的咬合干扰都应调改。而所需调改的咬合干扰是由于不正常咬合力引起了组织损伤,其中包括牙周的损伤、肌功能异常、颞颌关节紊乱。牙的功能接触(包括咀嚼和吞咽),在24小时内仅有17.5分钟,因
Physiological occlusion should be the same muscle position and teeth, the working side of chewing, the non-working side should be no contact, stretching the bite, the back teeth should be no contact, if the muscle position and the tooth position is not adjusted, indicating a high bite Existence: If the non-working side of the contact, the formation of occlusal interference, a harmful factor in the oral jaw system is often the underlying cause of temporomandibular joint disorders. Only a bite adjustment can remove this harmful factor. First, the adaptation of bite adjustment Bite interference is widespread in the population, but not all bite interference should be changed. The need to modify the bite interference is due to abnormal bite force caused tissue damage, including periodontal injury, abnormal muscle function, temporomandibular joint disorders. Tooth functional contact (including chewing and swallowing) was only 17.5 minutes in 24 hours due to
