【摘要】 目的:通过对咬合丧失或低位咬合患者咬合重建修复后的临床检查和咀嚼效率测量分析,讨论分析咬合重建修复治疗的临床和实验室效果,并从中总结经验,以指导咬合重建的临床操作,进一步提高口腔修复治疗的水平。 方法:从就诊患者中选取12名需行咬合重建修复者作为实验组,修复前进行必要的基础治疗,并检查记录TMD及其相关症状,然后进行合理的咬合重建修复。治疗完成1个月后,将修复后的TMD及其相关症状与修复前相比较,并对其咀嚼效率和咀嚼次数进行测量,与正常对照组之间进行比较,对相关数据进行统计分析。 结果: ①、修复后12名患者均感满意且咀嚼有力,其中4例感觉非常满意。其TMD症状得到改善,修复前后的统计学比较存在差别(p<0.05)。 ②、实验组与对照组之间的咀嚼效率(p<0.01)和咀嚼次数(p<0.01)均存在统计学差别,实验组的咀嚼效率约为对照组的66.39%—86.31%,平均为75.94%。 ③、固定组与活动组之间的咀嚼效率存在统计学差别(p<0.01),固定组优于活动组:固定组、活动组与对照组之间的咀嚼效率存在统计学差别(p<0.01)。 ④、对照组男女之间的咀嚼效率存在统计学差别,但其咀嚼次数不存在统计学差别。 ⑤、固定组与活动组之间咀嚼次数不存在统计学差别(p>0.01)。更多还原

【Abstract】 Objective: By way of checking the clinical symptom and determining the masticatory efficiency, to discuss and analyze the clinical and laboratory effect in those who were treated with occlusal reconstruction, to summarize experience, guide the clinical operation of occlusal reconstruction, further enhances the level of the oral rehabilitation.Methods: After necessary foundational treatment and recording the TMD and its correlated symptom, 12 patients were picked out from those who needed to be treated with occlusal reconstruction,then reasonable treatment was carried out with them. One month later, the TMD and its correlated symptom were recorded again. The masticatory efficiency and frequency were determinated and compared with the normal control group. The correlated data were statistical analysised.Results:① After treatment, 12 patients all felt satisfied and chewing powerfully, 4 examples felt satisfied extremely. Its TMD symptom is improved, statistics comparison existence difference (p <0.05).② Between the experimental group and the normal control group, the masticatory efficiency and frequency have statistics difference (p <0.01), themasticatory efficiency of the experimental group is approximately 66.39% -86.31% to the normal control, average is 75.94%.③ Between the fixed denture group and the removable denture group, the masticatory efficiency have statistics difference. The former is superior to the latter. There was also statistics difference (p <0.01) among the three groups of fixed denture, removable denture and normal control.④ Between the men and the women, There was statistics difference (p <0.01) in masticatory efficiency, but no statistics difference (p>0.01) in masticatory frequency.⑤ Between the fixed denture group and the removable denture group the masticatory frequency have no statistics difference (p>0.01).⑥ The masticatory efficiency and masticatory frequency have no linear correlation relations (r=0.1998, p>0.01) in the normal control group. Conclusions: After treated with occlusal reconstruction, the patient’s degree of satisfaction is high, its TMD symptom has the certain improvement; The patient’s masticatory efficiency although has difference from the normal control group, but it may reach to 66.39% -86.31% of the normal control group , the effect is ideal. The masticatory efficiency of occlusal reconstruction with fixed denture is obviously superior to with removabal denture. The masticatory efficiency is not totally dependent on the masticatory frequency, The difference between them is possibly the result which patient’s compatibility causes.更多还原
