上颌后牙缺失原位植入并上颌窦内提升同期种植治疗的短、中期效果研究

Short - term and mid - term follow - up study of 34 cases of maxillary posterior teeth deletion treated by orthotopic implantation combined with maxillary sinus floor elevation at the same time

目的 探讨原位植入并上颌窦内提升同期种植治疗上颌后牙缺失的应用价值及短、中期预后效果.方法 选取山西省中西医结合医院口腔科2014年6月至2016年6月收治的上颌后牙缺失患者68例为研究对象,采用随机数字表法分为对照组（n=34）与研究组（n=34）.对照组采取种植牙技术实施修复治疗,研究组采取原位植入并上颌窦内提升同期种植治疗,术后随访3～12个月.统计两组术后疼痛程度、并发症发生率、治疗满意度、术后12个月预后情况（种植体有无脱落及种植体松动）.结果 研究组疼痛程度优良率[97.06％（33/34）]高于对照组[76.47％（26/34）]（P〈0.05）;研究组并发症发生率[5.88％（2/34）]与对照组[8.82％（3/34）]比较差异无统计学意义（P〉0.05）;研究组治疗满意度[97.06％（33/34）]高于对照组[70.59％（24/34）]（χ2=8.758,P〈0.05）;研究组不良预后情况发生率[2.94％（1/34）]低于对照组[23.53％（8/34）]（χ2=4.610,P〈0.05）.结论 采取原位植入并上颌窦内提升同期种植治疗上颌后牙缺失,术后疼痛感较轻,治疗满意度较高,且并发症及术后12个月种植体脱落及松动发生率较低.

Objective To investigate the application value and short-term and mid-term prognosis of orthotopic implantation combined with maxillary sinus floor elevation in the treatment of patients with maxillary posterior teeth deletion at the same time.Methods A total of 68 patients with maxillary posterior teeth deletion in the Integrated Traditional Chinese and Western Medicine Hospital of Shanxi Province from June 2014 to June 2016 were selected and randomly divided into the control group（n=34）and the study group（n=34）according to the digital table.The control group was treated with dental implant technology to repair,and the study group was treated with implanted orthotopic implantation combined with maxillary sinus floor elevation at the same time.The follow-up was continued for 3-12 months after operation.The degree of postoperative pain,the incidence of complications,the satisfaction of the treatment,and the prognosis of the two groups after 12 months of operation（the exfoliation of implant and the loosening of the implant）were statistically analyzed.Results The good rate of pain in the study group was 97.06%（33/34）,which was higher than that of the control group [76.47%（26/34）]（P〈0.05）.There was no statistically significant difference in the incidence rate of complications between the study group [5.88%（2/34）]and control group[8.82%（3/34）]（P〉0.05）.The treatment satisfaction of the study group [97.06%（33/34）] was higher than that of the control group [70.59%（24/34）]（χ2 =8.758,P〈0.05）.The incidence rate of poor prognosis of the study group[2.94%（1/34）]was lower than that of the control group [23.53%（8/34）]（χ2 =4.610,P 〈0.05）.Conclusion Orthotopic implantation combined with maxillary sinus floor elevation in the treatment of patients with maxillary posterior teeth deletion at the same time has less postoperative pain and high treatment satisfaction.And the complications and incidence of exfoliation and loosening of implants are low after 12 months of operation.
