ABSTRACT
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.
