摘　　要：目的:评价重度牙周炎患者行All-on-4即刻负重种植义齿的临床效果。方法:对25例重度牙周炎致牙列缺失的患者行"All-on-4"即刻负重种植义齿修复。于永久修复3个月、6个月、12个月对种植体的菌斑指数、牙龈出血指数、探诊深度进行检查;并且对12个月时的种植体成功率、咀嚼效率、患者满意度进行评价。结果:永久修复1年后,种植体成功率为99%,咀嚼效率为(0.701±0.056)。永久修复3个月、6个月、12个月的菌斑指数无统计学差异;12个月时出血指数最高,差异有统计学意义(P<0.05);探诊深度6个月时最高,3个月时最低,差异有统计学意义(P<0.05)。患者对义齿的稳定性、发音满意度100%,美观性满意度92%,咀嚼功能满意度96%,舒适度满意度为88%。结论:"All-on-4"即刻负重种植义齿无论在牙周方面,还是在种植体成功率及咀嚼效率方面都有较理想的表现,患者满意度也较高,短期疗效可靠,长期疗效需进一步观察。Objective： To investigate the clinical results of all-on-4 for edentulous patients caused by severe periodontitis. Methods： Twenty-five patients were performed with all-on-4 at immediate implantation and immediate loading. Plaque index, sulcular bleeding index, and probing depth were measured at 3, 6, and 12 months after permanent restoration. The satisfied degree, masticatory efficiency, and success rate were calculated. Results： Success rate and masticatory efficiency were 99% and 69.97%, respectively at 12 months after permanent restoration. There was no significant difference in plaque index at 3, 6, and 12 months after permanent restoration. Sulcular bleeding index at 12 month was the highest （P＜0.05）. Probing depth after 6 months was higher than that after 3 months （P＜0.05）. The satisfied degrees for stability and articulation of denture were both 100%, for aesthetics was 92%, for masticatory efficiency was 96%, and for comfortability was 88%. Conclusion： All-on-4 showed good performance in the success rate and masticatory efficiency in short-term.
