牙槽嵴条件对全口义齿修复影响的临床研究

探讨无牙颌牙槽嵴条件,特别是下颌牙槽嵴条件对全口义齿修复效果的影响。方法无牙颌患者６２人,条件好组３０人,条件差组３２人,测试上下总义齿和固位力,咀嚼效率,和第一月,第三月的全口义齿满意度。结果不同牙槽嵴条件两组间的固位力,咀嚼效率,和第一月,第三月的总满意度及各单项满意虽略有差别。

A CLINICAL STUDY ON THE EFFECT OF RESIDUAL RIDGE ON THE COMPLETE DENTURES

Objective:To investigate the effect of residual ridge,especially mandibular residual ridge of edentulous patients on the complete dentures.Methods:Sixty two edentulous patients were included in this study,Thirty patients had good condition of mandibular residual ridge,other 32 were in bad condition.The retention of maxillary and mandibular complete dentures,and mastication efficiency were tested.One month and three months after having dentures, Patient Denture Satisfaction (PDS)was evaluated in all patients.Results:There was no statistically difference between two groups in the retention of complete dentures,mastication efficiency,general and every aspect PDS tested either in one month or three months,although slight difference existed in some aspects.Conclusion The clinical effect of complete dentures are influenced by multiple factors.The residual ridge is the base of prostheses,but not the only determining one.With nice design and fine manufacture,the edentulous patients with bad condition of residual ridge may get good restoration treatment.
