Abstract:
The aim of this ongoing prospective study was to determine the 36-month survival rate of short porous implants in the posterior maxilla with 2 to 7 mm of initial bone height in 48 patients. Forty-eight implants were placed; 35 were in sites with a bone height of 5 mm or less and 13 patients required sinus elevation with osteotomes in addition to a xenograft. All implants were loaded with single crowns. At the end of the follow-up period the survival rate was 97.92%. The use of short porous implants showed good predictability in the treatment of the posterior maxilla in this interim 3-year report.
