摘要
目的评价微型种植体用于种植修复前牙牙列缺损的效果，并与传统活动义齿和传统固定义齿进行比较。方法选取2012年1月至2014年12月在贵阳市口腔医院种植科行种植修复的患者26例为试验组，患者缺牙间隙3．5～5mm，采用微型种植体2．3～2．8mm30枚进行种植修复，术后3个月，进行氧化锆全瓷冠修复。修复后3、6、12、24个月进行临床和x线片的检查。另选取同期在该院修复科进行修复的患者48例为对照组，24例患者单个前牙缺失采用活动义齿修复，24例患者单个前牙缺失采用金属烤瓷桥修复。对种植义齿、活动义齿、固定义齿进行患者自我评分，在美观度、咀嚼功能、固位力、舒适度方面进行比较。结果2枚种植体发生松动后取出，其余种植体均成功进行了冠修复。种植体周围骨高度稳定，修复体外形美观、效果良好，患者对修复效果满意。种植义齿和传统固定义齿在各方面评分均远高于活动义齿（均P〈0．05）；种植义齿在舒适度方面优于传统固定义齿，其余方面二者相近；活动义齿在美观度方面评分高于其余3项。结论3．5～5mm缺牙间隙采用微型种植体种植修复可以取得良好的临床效果。
Objective To evaluate clinical effects of restorations in anterior teeth area with the microimplants and compare the effects between microimplant supported fixed dentures, removable partial dentures and poreelain-fused-to-metal（PFM） fixed bridges. Methods From January 2012 to December 2014, 26 eases of patients were selected as the experimental group in Guiyang Stomatologieal Hospital. Experiment group：The sample consisted of 26 consecutively treated partially edentulous patients who had a total of 30 mieroimplants, which were 2.3mm or 2.8mm in diameter and placed in 3.5-5mm edentulous space.The final restorations were fabricated with zireonia all ceramic crow 3 months later.All implants were examined clinically and radiologically in 3 months, 6 months,12 months and 24 months respectively.Another 48 cases of patients were selected as control group in the same period in the rehabilitation department of the hospital.Control group： A sample consisted of 48 patients who had a single missing tooth in the anterio teeth area.24 patients were treated with removable partial dentures（RPDs）. 24 patients were treated with PFM fixed bridges. After the denture completion, the satisfaction survey to the patients was made about the aesthetic resuhs, mastication, retention and comfort. Results Two loosing implants were removed, the remaining implants were successfully fabricated with crows.Bone level surrounding the implant is highly stable. Appearance of restorations had a good effect.The patients were satisfied with the mieroimplant supported fixed dentures.The satisfaction of patients with implant fixed dentures and PFM fixed bridges were higher than the patients with RPDs in aesthetic results, mastication, retention and comfort（P〈0.05）. The satisfaction of patients with implant fixed dentures was higher than the patients treated with PFM bridges in the comfort. No ohvious differences were observed about aesthetic results, mastication, retention satisfaction among implant fixed denture group and PFM fixed den
