摘　　要：目的比较中老年患者在分别完成无牙颌种植固定义齿(ISFP)或种植覆盖义齿(IOD)1~3年后种植体周围软硬组织、患者满意度和义齿并发症情况。方法选取2019年3月—2021年3月在南京大学医学院附属口腔医院就诊的43例中老年全口或半口无牙颌患者(50~80岁),根据患者的治疗情况分为2组,一组为种植固定义齿修复(ISFP组,28例),另一组为种植覆盖义齿修复(IOD组,15例),完成最终修复治疗后1~3年进行随访。对2组患者的修复后软硬组织变化等进行评估和对比。结果ISFP和IOD组患者在最终修复后1~3年种植体周围的软硬组织指标差异无统计学意义。ISFP组患者在修复后1~3年对义齿的固位力、咀嚼功能和语音功能的满意度显著高于IOD组,ISFP组分别为(9.179±0.700)分、(8.464±0.793)分、(8.179±0.772)分,而IOD组仅为(6.733±0.961)分、(6.467±0.915)分、(6.800±1.265)分,差异有统计学意义(均P<0.05),而对义齿的美观度和舒适度的评价2组差异无统计学意义。2组的机械并发症发生率差异无统计学意义。但是在机械并发症中,IOD组配件脱落或磨损发生率高于ISFP组,2组差异有统计学意义,2组的生物学并发症发生率差异无统计学意义。结论使用种植体支持的固定义齿和种植体支持的覆盖义齿均能够在一定范围内对无牙颌患者进行修复治疗,临床上要根据患者曾经的治疗情况和实际需要进行选择,同时也要考虑使用种植体支持的覆盖义齿可能存在后期较多并发症的可能。Objective To compare the soft and hard tissues around implants,patient satisfaction and denture complications of middle-aged and elderly edentulous patients after completing the implant supported fixed denture(ISFP)or implant supported overdenture(IOD)for 1-3 years respectively.Methods This study selected 43 middle-aged to elderly complete or partial edentulous jaws patients(between 50 and 80 years old)who were admitted in Nanjing Stomatological Hospital from March 2019 to March 2021.They were divided into two groups according to the clinical method of prosthesis.One group received implant supported fixed prosthesis(ISFP group,28 cases),another group was treated with implant supported overdenture(IOD group,15 cases),and the patients were followed up for 1-3 years after final restoration.The soft and hard tissue changes after repair were evaluated and compared between the two groups.Results There was no significant difference in the soft and hard tissue changes around the implants between the ISFP and IOD groups after treatment for 1-3 years.The ISFP group patients had achieved better denture retention,masticatory function,voice function and patients'satisfaction compared to the IOD group 1-3 years after the treatments,the ISFP group was(9.179±0.700)points,(8.464±0.793)points,(8.179±0.772)points,while IOD group was only(6.733±0.961)points,(6.467±0.915)points,(6.800±1.265)points,and the difference was statistically significant(all P<0.05),but there was no significant difference in the evaluation of the aesthetics and comfort level of dentures between the two groups.There was no significant difference in the incidence of mechanical complications between the two groups.However,in terms of mechanical complications,the incidence of parts shedding or wear in IOD group was higher than that in ISFP group,and the difference between the two groups was statistically significant,while the incidence of biological complications between the two groups was not statistically significant.Conclusion The application of implant-
