Comparing Conventional Dental Implants and Trabecular Metal™ Dental Implants After Sinus Floor Elevation

Specific Aims Primary Outcome Measures: • The objective of this study is to allow a preliminary analysis of the resonance frequency values over the 12 month period, which will be the primary outcome Secondary Outcome Measures: • To assess Crestal bone level maintenance Study Arms Bone Augmentation: Placement of two dental implants in Sinus augmented with Puros Cortico-Cancellous Particulate Allograft (70% Cortico and 30% Cancelleous) (Zimmer Dental- Carlsbad, CA, USA)- one implant will be TMDI (Zimmer Dental- Carlsbad, CA, USA) and the second will be Tapered Screw-Vent TSV-MTX (Zimmer Dental- Carlsbad, CA,USA). Implant stability will be determined by the initial insertion torque and RFV values at time of implant placement and after 1 month of healing on a monthly basis up until 12 months post implant placement. Sinus Elevation only: Placement of two dental implants as mentioned above in sinus augmented by sinus elevation procedure, blood clot and CopiOs Pericardium Membrane (Zimmer Dental- Carlsbad, CA, USA) only. One implant will be TMDI (Zimmer Dental- Carlsbad, CA, USA) and the second will be Tapered Screw-Vent TSV-MTX (Zimmer Dental- Carlsbad, CA,USA). Implant stability will be determined by the insertion torque and RFV values at time of implant placement and after 1 month of healing on a monthly basis up until 12 months post implant placement.
