舌侧集中和解剖式双侧平衡咀嚼能力的对比研究

Comparison of Chewing Ability between Complete Dentures with Lingualized Occlusion and Complete Dentures with Anatomic Bilateral Balanced Occlusion

目的比较舌侧集中和解剖式双侧平衡这2种型总义齿患者之间咀嚼能力的差异。方法以问卷的形式,采用VAS量化义齿咀嚼面包、豆腐干、胡萝卜、苹果、硬香肠、牛肉干和蛋炒饭7种不同食物的能力。在10例无牙颌患者依次戴用舌侧集中和解剖式双侧平衡总义齿8周后,比较2种型总义齿患者之间咀嚼能力(VAS评分)的差异。结果在咀嚼胡萝卜和苹果这2种食物时,舌侧集中总义齿VAS评分高于解剖式双侧平衡总义齿(均P<0.05);对其余食物,2种型总义齿VAS评分差异无统计学意义(均P>0.05)。结论舌侧集中总义齿患者在咀嚼较脆、较硬食物时比解剖式双侧平衡具有优越性。

Objective To compare the difference in chewing ability between complete dentures with lingualized occlusion and complete dentures with anatomic bilateral balanced occlusion.Methods The abilities to chew bread,dried tofu,carrots,apples,hard sausages,dried beef and egg fried rice were investigated and assessed using questionnaires and visual analogue scale（VAS） in 10 edentulous patients.The patients were treated successively with complete dentures with lingualized occlusion and complete dentures with anatomic bilateral balanced occlusion for 8 weeks.VAS scores were compared between the two treatments.Results The abilities to chew carrots and apples in patients with lingualized occlusion were significantly better than those in patients with anatomic bilateral balanced occlusion（P0.05）.There were no statistically significant differences in abilities to chew other foods between the two treatments（P0.05）.Conclusion Complete dentures with lingualized occlusion offers a superior level of masticatory performance for chewing hard and friable foods,compared with complete dentures with anatomic bilateral balanced occlusion.
