摘要:

目的 探讨全口无牙颌患者应用固定种植修复后的咬合特点。方法 选取30例全口无牙颌种植固定修复患者作为试验组,30例天然牙列受试者作为对照组,使用Teetester数字化咬合分析系统分析二者在牙尖交错位、前伸颌位、侧方颌位等不同位的咬合时间及咬合力分布等特点。结果 牙尖交错位时,试验组的咬合接触时间、最大咬合力均小于对照组(P<0.05),而最大咬合力时左右侧咬合力平衡度则相反;前伸颌位时,试验组的咬合分离时间小于对照组(P<0.05);侧方颌位时,试验组的咬合接触时间小于对照组(P<0.05)。二者的平均咬合压力、前牙区总受力百分比、侧方颌的颌型均无统计学差异。结论 全口无牙颌种植固定修复患者牙尖交错位时的最大咬合力会降低,但与天然牙列相似的是,前伸颌位时咬合力量均集中在前牙区,侧方颌位时均以组牙功能为主。

Abstract:

Objective This study aims to evaluate the occlusal characteristics of full edentulous patients with implant-supported prostheses and to provide a reference with the occlusal situation for clinicians.Methods A Teetester occlusal analysis system was used with 30 full edentulous patients of implant-supported fixed denture (test group) in comparison with 30 natural dentition (control group). The percentage of occlusal force distribution were measured, as well as the occlusal time at the intercuspal, protrusion, and left and right lateral positions.Results Compared with control group, the occlusion time, maximum occlusal force in intercuspal of test group significantly reduced (P<0.05); while control group was obviously supe-rior to test group in the left and right bit force degree. Disclusion time in protrusion, occlusion times in lateral positions of test group also significantly reduced (P<0.05). There were no significant differences in average occlusion force, percentage of total force in anterior teeth, and lateral occlusion between test group and control group.Conclusion The maximum occlusal force in intercuspal of full edentulous patients with implant-supported prostheses reduce. The occlusal force in protrusive occlusion is concentrated in the front teeth, and the group function occlusion is the main lateral occlusal pattern.
