摘要
目的 比较热凝树脂基托全口义齿与注塑基托全口义齿修复低平牙槽嵴患者的咀嚼效率.方法 选择无牙合且牙槽嵴低平的患者共30例,按随机数字表法均分为两组,每组各15例.其中一组患者第1个月首先佩戴热凝树脂基托全口义齿,1个月后测量咀嚼效率,然后停止佩戴任何义齿1周,再佩戴注塑基托全口义齿1个月,1个月后测量咀嚼效率;另一组患者第1个月首先佩戴注塑基托全口义齿,1个月后测量咀嚼效率,然后停止佩戴任何义齿1周,再佩戴热凝树脂基托全口义齿1个月,1个月后测量咀嚼效率.以吸光度法测定患者咀嚼效率（OD值）.结果 患者佩戴1个月热凝树脂基托全口义齿的咀嚼效率（OD值）为（0.608±0.124）,佩戴1个月注塑基托全口义齿的咀嚼效率（OD值）为（0.885 ±0.071）,经检验,注塑基托全口义齿的咀嚼效率明显高于热凝树脂基托全口义齿（t=14.845,P＜0.05）.所有患者在试验期间均未出现明显不良反应.热凝树脂基托全口义齿修复后咀嚼效率明显提高者共13例,提高率43.33％,注塑基托全口义齿修复后咀嚼效率明显提高者共24例,提高率80.00％,注塑基托全口义齿修复后的咀嚼效率提高率明显高于热凝树脂基托全口义齿（χ2 =31.582,P＜0.05）.所有患者在研究期间未出现明显不良反应.结论 注塑基托全口义齿的制作精确度较高,咀嚼效率优于热凝树脂基托全口义齿,修复效果更加,值得临床推广.
Objective To compare the masticatory efficiency of alveolar ridge restored by thermosetting resin full denture base and cast resin full denture base.Methods 30 patients with alveolar ridge were selected and divided intothe two groups by random number table and 15 cases in each group.Full denture with thermosetting resin base was worn in the first month in one group,and masticatory efficiency was measured.Then no false tooth was worn for a week,then full denture with cast resin base for a month,then masticatory efficiency was measured.In the other group,full denture with cast resin base was worn in the first month,and then masticatory efficiency was measured.Then no false tooth was worn for a week,then full denture with thermosetting resin base was worn for a month,then masticatory efficiency was measured.OD value as masticatory efficiency was measured by absorption spectrophotometry.Results The masticatory efficiency（OD value） of full denture with thermosetting resin base was （0.608 ± 0.124）,and full denture with cast resin base was （0.885 ± 0.071）.The masticatory efficiency of full denture with cast resin base was higher than that with thermosetting resin base （t =14.845,P 〈 0.05）.There was 13 cases of increased masticatory efficiency with hot coagulation resin base denture repair,the improved rate was 43.33 %,while 24 cases with injection molding denture base denture repair,and the improved rate was 80.00%.The rate with injection molding denture base denture repair was higher than that with hot coagulation resin base denture repair（χ2 =31.582,P 〈 0.05）.There was no significant adverse reaction in duration of test among all the patients.Conclusion The definition of full denture with cast resin base manufacture was high,and the masticatory efficiency of full denture with cast resin base is higher than that with thermosetting resin base,and the repair effects is better.It is worth of clinical application.
