A Retrospective Study of Sintered Porous-Surfaced Dental Implants in Restoring the Posterior Maxilla

ABSTRACT

PURPOSE: The purpose of this retrospective report was to analyze long-term survival rate of sintered porous-surfaced dental implant (Endopore(R) Dental Implant system, Innova Corporation, Toronto, ON, Canada). METHODS: 61 partially edentulous patients were received a total of 127 Endopore dental implants in the maxilla. Of the 127 implants, 24 implants were restored with individual (ie, non-splinted) crowns, while 103 implants were splinted to other implants. Medical records and radiographs were evaluated and analyzed by the cumulative survival rate, location of implants, implants length and diameter, crown/implant ratio and whether the implant was splinted. Chi squire test was used statistically. RESULT: Of the 127 implants, 8 implants (6.3%) were removed and and cumulative survival rate was 93.7%. CONCLUSION: Endopore implants showed satisfactory results after up to 8 years function periods in the edentulous posterior maxilla.
