There was no significant difference of early failure among four implant locations, which were anterior maxilla, posterior maxilla, anterior mandibular and posterior mandibula (P=0.709). The failure rate of smokers (1.3%) was higher significantly than that of non-smokers(0.3%,P<0.01). The failure rate of the patients ≥40 years old (1.0%) was higher significantly than that of the patients <40 years old(0.4%, P=0.033). There was no significant difference in gender between the failed implants and success implants (P=0.692). The rate of early dental implant failure was 0.8% at individual level and 0.5% at implant level.
There were 36 patients with 36 early failed implants and 4 381 patients with 6 564 success implants.
#Ibm spss statistics 19.0 software
Statistical analysis software was IBM SPSS Statistics 19.0.
Statistical methods were χ 2 test and descriptive analysis, P<0.05 had statistical significance. The general conditions of early failure patients, the early failure occurrence time, treatment and prognosis were recorded. The differences of gender,age,smoking,location of implants, healing abutments and bone graft were compared between early failed implants and success implants. To analyze the risk factors of early dental implant failure,treatment and prognosis.Ĭases of dental implants in the first clinical division from January 2000 to December 2016 were selected according to inclusion criteria.
