Study summary

This will be a prospective, randomized multicenter study to determine the safety and efficacy of the T3 Certain Tapered with DCD as compared to T3 Certain Tapered without DCD. All implants will be placed in the maxilla or mandible in a single stage manner and loaded with prosthesis after 6 weeks of healing. Final restorations will take place no later than 4 months following implant placement surgery. The implants will be evaluated yearly for 2 years.

Read the detailed description

This is a multicenter, prospective, randomized study that will assess the the safety and efficacy of the implant systems with:

  • Resistance to countertorque testing (mobility)
  • Implant Stability Quotient (ISQ)
  • Changes in peri-implant crestal bone levels
  • Confirmation of clinical benefits

A total of 60 implants, 30 per treatment group will be placed across all participating sites. One patient may contribute more than 1 implant. All implants/ patients will be followed for up to 2 years.

Study arms

  • Experimental
    T3 Certain Tapered implant with DCD

    Implant will be placed in the maxilla or mandible in a single stage manner and loaded with prosthesis after 6 weeks of healing. Final restorations will take place no later than 4 months following implant placement surgery. The implants will be evaluated yearly for 2 years.

    Device: T3 Certain Tapered Implant

  • Active comparator
    T3 Certain Tapered implant without DCD

    Implant will be placed in the maxilla or mandible in a single stage manner and loaded with prosthesis after 6 weeks of healing. Final restorations will take place no later than 4 months following implant placement surgery. The implants will be evaluated yearly for 2 years.

    Device: T3 Certain Tapered Implant

Interventions

  • DeviceT3 Certain Tapered Implant

    Patients will be randomized to receive either the T3 Certain Tapered with DCD (Test) or the T3 Certain Tapered without DCD (control/active comparator). Both types of implants will be rehabilitated in the same manner (early loading)

What researchers measure

Primary outcomes

  1. Implant survival

    Assessed by lack of mobility, resistance to countertorque testing, implant stability measurement

    Time frame: 2 years

Secondary outcomes

  1. Peri-implant crestal bone levels

    Assessed by radiographic measurements of serial crestal bone levels

    Time frame: 2 years
