Abstract:
Objective The lack of observation on domestic BLB implant affect its longterm maintenance. The long-term clinical effect of domestic BLB implant system was evaluated by a 10-year follow-up.Methods A total of 179 implants were placed in 120 patients from January 2004 to December 2005 in Nanjing Stomatological Hospital. Patients accepted implant pattern of stage Ⅰ implantation and stage Ⅱ delayed exposure and prostheses were completed. Upper crowns were either screw-retained or cemented. Follow-up observation includes post-operation immediately, pre-secondary operation, 3 months and annually.Results Until December 2017, the rate of loss of follow-up was 6% and the overall survival rate was 95.2%. Implant failures were mainly due to the looseing of implant system caused by bone resorption and infection. Prosthetic complications include abutment loose, central screw loose, food impaction and porcelain fracture. There were no significant differences of failure cases comparing maxillary and mandible (P>0.05); neither comparing anterior teeth, pre-molars and molars (P>0.05)Conclusion When clinical indication is strictly controlled, BLB implant system is suitable for partially edentulous patients.
