Trial Outcomes & Findings for Comparing Conventional Dental Implants and Trabecular Metal™ Dental Implants After Sinus Floor Elevation (NCT NCT02404649)

NCT ID: NCT02404649

Last Updated: 2020-07-22

Results Overview

Implant stability quotient (ISQ) is the value on a scale that indicates the level of stability and osseointegration in dental implants. The scale ranges from 1 to 100 and is measured by implant stability meters instruments using resonance frequency analysis (RFA) technique. The acceptable stability range lies between 55-85 ISQ. Lower initial stability will normally increase with time due to the lower mechanical stability being enforced by the bone remodeling process (osseointegration). The overall average ISQ value of all implants over time is approximately 70. A significant decrease in ISQ indicates a potential problem and should be considered an early warning. For each time period three measurements were taken from three different positions on the dental implant and the measurements were averaged for each time period.

Participant Flow

Recruitment of patients were fulfilled in a timely manner. Patients were were down from the existing patient pool at the Harvard School of Dental medicine.

Three participants were excluded from the trial due to early dental implant failures. These three events were caused by local infections and thus subsequent readings were not taken.

Measure
Bone Augmention
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. Thickness of bone surrounding implant body positioned in the sinus will be measured.

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).
