过度磨耗引起咬合过低的修复治疗

Prosthodontic treatment of lower occlusal contact induced by excess abrasion

重度、不均匀的磨耗导致的咬合关系异常是咬合病最常见的一种形式。过度磨耗引起咬合过低的病例在临床中很多见,尤其是年龄较大的中老年患者居多。往往由于延误治疗时机及患者本身的不重视,就诊患者均伴有面型改变、牙体牙髓组织病变,甚至颞下颌关节异常等症状。在临床工作中,对此种病例采用咬合重建的治疗方法,达到了理想的治疗效果。所建立的新型的咬合接触关系不仅改善了面型及牙齿的美观,并且恢复了咀嚼系统的功能、牙周支持组织和颞下颌关节的组织结构功能。
