改良咬合重建治疗严重交错咬合的临床研究

A clinical study of improved occlusal reconstructions to partial denture arches with seriously interlaced occlusion

目的探讨治疗严重交错咬合的上下牙列缺损病例有效实用并且价格较低廉的治疗方法。方法对严重交错咬合患者进行固定与铸造颌垫式可摘局部义齿联合修复咬合重建，在治疗前后分别进行咀嚼效率的检测和颞颌关节功能检查。结果治疗后，患者咀嚼功能显著提高，颞颌关节功能有了明显的改善。结论固定与铸造颌垫式局部义齿联合修复咬合重建是治疗严重交错咬合患者有效的方法之一。

Objective To investigate the effective and inexpensive therapy to partial denture arches with seriously interlaced occlusion. Methods Occlusal reconstructions with fixed and removable prosthesis were taken to cure partial denture arches with seriously interlaced occlusion. Masticatory efficiency was measured and X-rays of Sehillers position were taken before and after therapy. Results After therapy masticatory efficiency was raised. And the function of TMJ was better. Conclusion Occlusal reconstruction with fixed and removable prosthesis is an effective way to eure partial denture arches with seriously interlaced occlusion.
