Purpose: The aim of this study was to evaluate the survival rate of sintered porous-surfaced implants placed in the edentulous posterior mandibles, in relation to implant length and diameter, crown-to-implant ratio, and types of prostheses, for a maximum of eight years of functioning.
Material and Methods: The study group consisted of 43 partially edentulous patients who visited Catholic University Hospital of Daegu and one private dental clinic. A total of 122 sintered porous-surfaced implants - Endopore<SUP>R</SUP> (Innova Life Sciences, Toronto, Ontario, Canada) - were placed in the edentulous posterior mandibles. Two diameter sizes (4.1 ㎜ and 5.0㎜) and four lengths (5.0㎜, 7.0㎜, 9.0㎜, and 12.0㎜) were used. One hundred and three implants were splinted and 21 implants were non-splinted. The survival rates of the implants in relation to length, diameter, crown-to-implant ratio, and types of prostheses were investigated. Statistical data were analyzed using SPSS Win. Ver 14.0 software with the Chi-square test.
Results: The survival rate of the 4.1㎜ diameter implants was 100% and 91.2%) for the 5.0㎜ diameter implants. The survival rates of the implants of differing diameters were found to be statistically different (p=0.005). The survival rates of both the 5.0㎜ and 7.0㎜ length implants were 100%. The survival rate of the 9.0㎜ length implants was 97.9% and for the 12.0㎜ length implants was 95.1%. There was no statistical difference in survival rates for the differing lengths of implants. Of the 103 prostheses that were splinted, the survival rate was 98.0%. The survival rate of splinted prostheses was higher than that of the non-splinted prostheses, but was found to be not statistically different. There were no failed cases when the crown-to-implant ratio was under 1.0. When the crown-to-implant ratio was between 1.0 and 1.5, the failure rate of the implants was 6.7%. No failure was recorded with the ratio range of 1.5 to 2.0. Relative to the crown-to-implant ratio of 1.0, the failure rates were statistically different (p=0.048).
Discussion and Conclusion: The cumulative survival rate of the porous-surfaced implants placed in the edentulous posterior mandibles was 97.5%. Short porous-surfaced implants showed satisfactory results after a maximum of nine years of functioning in the edentulous posterior mandibles.
