NCT00318487

Brief Summary

Fifteen (15) patients completely edentulous in the maxilla will be treated with 8 dental implants. The total treatment will be done in 2 stages to allow, within the same group, a study of two different approaches. Miniscrews that can be functionally loaded will be provided by 3i with the design and surface textures as wanted by the study sponsor.

Outcome Measures

Primary Outcomes (6)

  • Comparison of 3i dental implants installed simultaneously with a sinus lift procedure and immediately loaded

    4 months

  • Comparison of sinus lift with autogenous iliac crest bone + Bio-Oss and sinus lift with an autogenous calvarial skull bone + Bio-Oss

    4 months

  • Installation of implants Prevail and Certain in sinus lift area and naturally healed (non-lifted) bone

    4 months

  • Histological comparison between immediately loaded implants in sinus lifted bone versus normal bone

    4 months

  • Histological comparison at various time intervals

    4 months

  • Histologic findings: integration of the graft, amount of new bone formation, survival and success of the implant, and osseointegration of implant

    4 months
