    The study will attempt to show that the Ponto 4.5mm Wide Diameter implant has similar or better outcomes in terms of Quality of Life (QoL) benefit; implant extrusion and revision surgery when compared to the 3.75mm diameter implant.

  • To determine that Ponto 4.5mm Wide Diameter implant has similar or better outcomes in terms of Quality of Life (QoL) benefit when compared to the 3.75mm diameter implant [ Time Frame: 3 months ] [ Designated as safety issue: No ]
    The study will attempt to show that the Ponto 4.5mm Wide Diameter implant has similar or better outcomes in terms of Quality of Life (QoL) benefit; implant extrusion and revision surgery when compared to the 3.75mm diameter implant.

  • To determine that Ponto 4.5mm Wide Diameter implant has similar or better outcomes in terms of Quality of Life (QoL) benefit when compared to the 3.75mm diameter implant [ Time Frame: 6 months ] [ Designated as safety issue: No ]
    The study will attempt to show that the Ponto 4.5mm Wide Diameter implant has similar or better outcomes in terms of Quality of Life (QoL) benefit; implant extrusion and revision surgery when compared to the 3.75mm diameter implant.

  • To determine that Ponto 4.5mm Wide Diameter implant has similar or better outcomes in terms of Quality of Life (QoL) benefit; implant extrusion and revision surgery when compared to the 3.75mm diameter implant [ Time Frame: 12 months ] [ Designated as safety issue: No ]
    The study will attempt to show that the Ponto 4.5mm Wide Diameter implant has similar or better outcomes in terms of Quality of Life (QoL) benefit; implant extrusion and revision surgery when compared to the 3.75mm diameter implant.


Secondary Outcome Measures:
  • Determine if the 4.5 mm implant is sufificiently stable in the temporal bone to load the sound processor at 3 weeks postoperatively [ Time Frame: 3 weeks ] [ Designated as safety issue: No ]
    Presently, the recommendations to load the sound processor on a bone anchored implant is 3 months (for adults). Using outcome measures, i.e., OSTELL ISQ data is one method to determine implant stability at different intervals

  • Implant Stability Quotient [ Time Frame: At surgery ] [ Designated as safety issue: No ]
    Implant Stability Quotient (ISQ 26) is a measurement scale used for Resonance Frequency Analysis (RFA) when evaluating implant stability. The measurement is performed by utilizing the Osstell® ISQ and Osstell Mentor stability meters provided by Osstell. The ISQ values range from 1-100. The more stable the implant, the higher the ISQ value.
