治疗性义齿对无牙颌患者义齿空间的影响及临床效果评估

目的探究治疗性义齿对无牙颌患者义齿空间变化的影响,并对其临床疗效进行系统性评估。方法对20例接受治疗性义齿治疗的患者进行治疗前后满意度问卷调查,填写口腔健康影响程度量表(oral health impact profile,OHIP?14),收集义齿空间、义齿组织面、咬合印迹、哥特式弓描记图像、黏膜状态、偏侧咬合状态、咬合力、固位稳定、患者咀嚼能力、义齿满意度及OHIP?14评分等数据进行统计分析。结果本研究中受试者通过治疗性义齿的治疗,义齿空间得到改善,义齿的组织面的组织调理剂逐渐分布均匀,咬合印迹逐渐对称、均匀,哥特式弓描记图像显示关节、神经和肌肉逐渐稳定,口腔黏膜转变为健康状态,偏侧咬合情况有所改善,咬合力、固位稳定性和主、客观咀嚼能力也较治疗前有显著提高,在治疗前后的患者满意度及OHIP?14评分均有明显改善,差异有统计学意义(P<0.05)。客观咀嚼能力与义齿的固位稳定性、主观咀嚼能力和义齿满意度呈正相关;而与OHIP?14评分呈负相关。结论治疗性义齿有助于恢复理想的无牙颌义齿的空间,并且能改善患者的口腔健康状况,提高义齿的固位与稳定和咀嚼能力,从而提高患者的满意度,有临床应用的价值与推广的潜力。

Effect of treatment dentures on denture space in edentulous patients and its clinical evaluation

Objective To investigate the effect of treatment dentures on changes in denture space in edentulous patients and to evaluate its clinical effect.Methods Twenty patients with treatment dentures were investigated with a questionnaire and Oral Health Impact Profile(OHIP?14)before and after treatment.The denture space,denture tis?sue surface,occlusal points,Gothic arch images,mucosal condition,lateral occlusal condition,bite force,retention and stability,patient mastication ability,denture satisfaction,and OHIP?14 score were collected for statistical analy?sis.Results After wearing treatment dentures,the denture space significantly improved,the tissue conditioners on the treatment denture gradually began to be distributed,and the occlusal points gradually became symmetrical.The gothic arch images showed that the joints,nerves,and muscles gradually stabilized.The mucosal condition changed to a healthy state.The lateral occlusal conditions were improved.There were also significant differences in the bite force,retention and stability,subjective and objective chewing ability,satisfaction with the denture and OHIP?14 score before and after treatment(P<0.05).The objective chewing ability was positively correlated with the retention stability of the denture,the subjective chewing ability and the satisfaction of the denture,and it was negatively corre?lated with OHIP?14.Conclusion Treatment dentures could help to restore denture space to an ideal condition and improve the oral health of patients.This treatment could also improve the retention and stability of the denture and the chewing ability to improve patient satisfaction.This treatment has clinical application value and promotion poten?tial.
