Abstract：AIM:To observe the implant survival rate and prosthetic complication of mandibular overden-ture retained by ERA mini dental implants.METHODS:This retrospective clinical study was conducted on a group of mandibular edentulous patients (n =20)treated with overdenture retained by ERA mini dental implants via clinical ex-aminations and clinical data.Implant survival rate,prosthetic complications and maintenance were recorded.The relat-ed risk factors were also analyzed.RESULTS:During the observation time of 4.3 ±0.6 years,4 of the 71 ERA mini -implants were removed,the survival rates was 94.4%.One implant was removed because of periimplantitis,the other three failed due to lack of osseointegration.The most common prosthetic complications were detachment of abut-ments which had been bonded to implants(n =19),followed by wear/damage of patrix(n =14),relines of overden-tures(n =10),pain(n =11),occlusal adjustments(n =7)and fracture of mandibular overdenture(n =3).CONCLU-SION:In this clinical study,the survival rate of ERA mini dental implants is similar to that of the standard implants. Requiresregular prosthetic maintenance is required for the control of prosthetic complication.
