摘　　要：目的:探讨第二磨牙游离缺失、对颌磨牙间垂直型食物嵌塞的不同修复方法与效果。方法:选择198例垂直型食物嵌塞患者分2组,每组99例,一组嵌塞间隙远中牙齿只做全冠修复,另一组嵌塞间隙远中牙齿全冠修复后对颌缺失处再行可摘局部义齿修复。1年后复查嵌塞情况,并行统计学分析。结果:99例全冠修复的患者中43例治愈,8例明显改善,48例失败。99例全冠修复后对颌缺失处行可摘局部义齿联合治疗的患者中治愈97例,明显改善1例,失败1例。两种方法差异有统计学意义(x2=59.91,P<0.05)。结论:全冠修复加可摘局部义齿修复的联合运用对于治疗第二磨牙游离缺失、对颌磨牙间食物嵌塞的病例可取得良好的临床效果。Objective： To investigate clinical effects of different repair methods for second molar distal-extension edentulous combined with vertical food impaction of opposite teeth. Methods： 198 cases were divided into two groups. Patients were restored with full crowns for the second distal molars which were involved in vertical food impaction with or without removable partial dentures for the opposite second molar distal-extension edentulous in control group and experimental group respectively. All cases were followed up for one year. Results： In the control groups, 48 patients （48.4%） were failed. In the experimental group, 97 patients （98.0%） were cured with only one （1.01%） failed. The differences were statistically significant. Conclusion： Full crown restoration combined with removable partial denture was confirmed as a efficient clinical method for restoring the vertical food impaction with opposite second molar distal-extension edentulous.
